IOTA: Best May occ'n in N.America May 17; many other good events

I received the following update from David Dunham of the International
Occultation and Timing Association, and want to pass it along for your
information.

Ed Flaspoehler, AAAA
www.AstroMax.org

1. We need help to observe the occultation of an 8.4-mag. star by
the large 166-km asteroid (54) Alexandra Tuesday morning, May 17,
from the central USA, western Texas, and northwestern Mexico, the
best asteroidal occultation in North America this month.

2. The best May occultation worldwide will be of an 8.3-mag. star
by the 200-km asteroid (7) Iris on the 22nd, visible from w. & s.e.
Europe, the Middle East, and southern Asia. Other good events will
occur in Latin America, Ontario, and the northeastern USA.
Information about many other asteroidal occultations around the
world to May 22, and a summary of the best events for the rest of
2005, are listed.

3. First station list for the May 17th Alexandra occultation.
__________________________________________________ _____

1. Observers in Nebraska, Kansas, western Oklahoma, western Texas,
and northwestern Mexico are strongly encouraged to monitor 8.4-mag.
SAO 210301, spectral type A0, only about 5' northeast of 5th-mag.
kappa Coronae Australis. I plan to observe the event from s. Baja
Calif. with some other observers, but we can only cover the northern
4/10ths of the path; mobile observers in the USA are encouraged to
cover more the southern half of the path, unless the weather
forecast turns out to be poor for Baja. Please let me know your
plans so we can try to coordinate coverage of this bright event; I
will distribute an updated station list sometime Saturday. A first
version of the station list is below, at the end of this message,
from Dave Herald, including probabilities and altitude of the star
above the s. horizon. I will be travelling starting early on May
15th, so from then until my return the evening of May 18th, I might
not be able to get e-mail here; during that time, copy all messages
for me to Kerry Coughlin in La Paz at
.

The occultation starts at 8:12 UT = 3:12 am CDT in North
Dakota, but altitude will be only 2-3 deg. above the southern
horizon. The altitude increases as the shadow moves south; Omaha is
just inside the southern 1-sigma limit at 8:13 UT and the path
sweeps across Kansas stating a minute later. At 8:15 UT, Oklahoma
City might have an occultation, also just inside the 1-sigma s.
limit. The path reaches the Big Bend/Ft. Davis region of w. Texas
at 8:20 UT. The path then sweeps across n.w. Mexico (Chihuahua at
8:22 UT = 2:22 am MDT) and goes over the southern end of Baja
California at 8:26 UT (2:26 am MDT).

If an occultation occurs, there will be a 3-mag. drop lasting a
long 87 seconds for a central occultation. The star is at J2000
RA 18h 33m 39.6s, Dec -38 deg. 39' 07", only about 5' northeast of
5th-mag. kappa Coronae Australis. There are other 5th-mag. stars to
use to star-hop to it from 3rd-mag. eta Sagittarii about 4 deg.
northwest of the target, and from 2nd-mag. Kaus Australis (epsilon
Sagittarii) about 5 deg. north and a little west of the target.
You can see the path map, and detailed finder charts at different
scales if you click in the right-hand box for the event in the list
on Steve Preston's Web site at http://www.asteroidoccultation.com .

2. The best May occultation worldwide will be of an 8.3-mag. star
by the 200-km asteroid (7) Iris on the 22nd, visible from w. & s.e.
Europe, the Middle East, and southern Asia. Dozens of observers in
at least ten countries are making plans to cover the path of this
event; if the weather cooperates, it could be the best-observed
asteroidal occultation this year. On May 17th, (146) Lucina, which
likely has a small satellite based on an early video observation of
another occultation by this asteroid, wil occult a 9th-mag. star in
Hispaniola and Nicaragua, and then on the 30th it will cover an 8th-
mag. star in southern South America. On May 30th, a 9th-mag. star
will be occulted by (786) Bredichina across central N. America.

Updated information about the events mentioned above and other
asteroidal occultations visible from North and South America,
Europe, Asia, Australia and other areas to 2005 May 22nd, and
preliminary updates for a few later events, are summarized
according to calculations by Steve Preston (comprehensive here only
for North America; occultations of brighter stars given for other
areas) and Jan Manek and Jean Schwaenen (for Europe) in the tables
for asteroidal occultations below. Updated path maps, finder
charts, and other detailed information about these events can be
found at the Web sites at the end of this message; Steve Preston's
Web site also has path updates for South America, Australia, New
Zealand, Japan, and often other areas, while Jan Manek's site covers
Europe and southern Africa (but some European events are instead on
Preston's site, especially trans-Atlantic events, and many others
are on the EAON site by Schwaenen); you should consult them since I
mainly list the better foreign and North American events here.
Also, those Web sites now have information covering most of the rest
of March; I will distribute summaries of those events soon. Under
"Approx. location", places are spelled out when they can be, but
usually it is necessary to use the standard two-letter postal
abbreviations for the States of the USA and provinces of Canada (for
example, AB = Alberta, NB = New Brunswick, NE = Nebraska) or the
two-letter country abbreviations used in Web and e-mail addresses
(FR = France, DE = Germany, NZ = New Zealand, etc.). A complete
list of these codes is at
http://www.nwhealth.edu/it/employs/abbrev.html . "cen." or "c"
means central, and small letters, with or without ".", indicate the
part of the State, Province, or country, such as sCA = southern
California, nON = northern Ontario, sTX = southern Texas, etc.
Rarely, 3-letter airport abbreviations are used, and I use "Sib" for
Siberia, NN for New England, and CS for the Canary Islands (rather
than just "ES" to distinguish them from mainland Spain; can't use CI
because that's Cote d'Ivoire (Ivory Coast). Often, not every place
crossed by a path is mentioned, so if you are between two listed
states or countries, the event may occur in your location; also, due
to remaining path errors, if you are in adjacent areas, you should
also watch since the actual path might occur at your location.
Unless otherwise specified in the notes, the magnitude drop in case
of an occultation is 1.0 or more. Those especially in the Americas
are reminded that the dates and times below are U.T., and that local
dates may be a day earlier. NOTE that the times are U.T.;
especially in the Americas, events often occur the evening of the
PREVIOUSLY-LISTED date, local time.

Notes for Individual Events:

May 14, Honda: The star is PPM 292574, spec. type G0. The path misses
the Earth's surface by a few hundred km, but the uncertainty is large
enough that an occultation is possible at low altitude in Virginia,
West
Virginia, and surrounding States.

May 15: This is the asteroid, not the Galilean satellite of Jupiter.
The weather forecast is good for most of the path and several in this
wide path are planning to observe it.

May 16, Sylvania: The star is SAO 190044, spectral type F5.

May 16, 1989 BQ: Trojan asteroid. The path is very uncertain.

May 16, 2005 AB: This near-Earth asteroid may be larger, based on a
long visual occultation timed at an earlier occultation.

May 16, Pythia: The star is SAO 140577, spectral type G0.

May 16, Xosa: The star is SAO 160986 = HIP 88193, sped. type B3.

May 17: Lucina ang. diam. 0.113" is suspected of having a small
satellite a few hundred km away, so observers throughout the Caribbean,
Florida, s. Mexico, Central America, and Venezuela are encouraged to
monitor the star for a possible event. The predicted central dur. is
15.3 seconds. The star is SAO 160597 = HIP 85690, spectral type F5.

May 17, Panopaea: This is a nice wide path, but the star is faint,
fainter than the asteroid, so only a 0.6-mag. drop is expected, easy
with video but difficult visually. If you live, or can travel, a
little
farther northwest, you can be in the much better Alexandra event path.

May 17: Alexandra ang. diam. 0.162"; occ. dur. 87s.
The star is SAO 210301, spectral type A0, only about 5' northeast of
5th-mag. kappa Coronae Australis; see much more in item 1 above.

May 18, Brigitta: The star is SAO 58506, spectral type A2.

May 18, Adams: The star is SAO 206637 = HIP 75558, spectral type A0.

May 20, Koranna: The star is SAO 127680, spectral type K2.

May 21: Kassandra ang. 0.055". The star is PPM 125592, sp. type F5.

May 21, Adriana: The star is SAO 139884, spectral type G5.

May 22: Iris ang. diam. 0.148". The path also passes over s.Pakistan,
s. Iran, part of United Arab Emirates, Kuwait,nwSA,sIraq,and sUK (low).
The star is SAO 184864 = HIP 83097, spectral type A8/A9V.

May 24: Several more events from May 24 to June 10 have been updated
and posted by Steve Preston, and some others are on the EAON Astrosurf
Web site (Schwaenen) with links given below.

May 30: Lucina ang. diam. 0.117"; see May 17th Lucina note. The star
is SAO 160464 = HIP 84809, spectral type F5V.

May 30: Bredichina ang. diam. 0.070". This path also
passes over western lower Michigan, se Wisc. (Milwaukee), & nw
Arkansas. The predicted n. limit passes over Tulsa, Oklahoma City,
and Hermosilo, Sonora, MX while St. Louis and Dallas-Ft. Worth are
near the s. limit. With a 1-sigma shift, Kansas City and El Paso
could have an occultation, while a 1.5-sigma shift to the south
would put Indianapolis and Austin, TX in the path, which passes over
central Baja California. The star is SAO 186978, spectral type B9.
I will be at a business meeting in Orange County, Calif. a few days
before this event and have arranged to stop over in El Paso on my
return home so I can observe this occultation from western Texas;
hope others can put this good event in their holiday plans.

June 2: Doris ang. diam. 0.109". The star is SAO 145585, sp. type K0.

June 4: Seppina ang. diam. 0.039".

June 6: Elpis ang. diam. 0.069". The star =SAO145585 =HIP44831,sp.K5.

Steve Preston's maps and data for events after June 10 can be found at
http://iota.jhuapl.edu/mpearly.htm .

June 13: Pallas ang.diam. 0.30". The star =SAO 82277 =HIP60368,sp.K2.

June 27: Francette ang. diam. 0.035". The star is SAO 140606, sp. K2.

July 7: Lamberta ang. diam. 0.114". The star is SAO 212801 = HIP
104753, sp. K0. Duluth, Minneapolis, Omaha, & Lubbock are in the path.

July 12: Kallisto ang. diam. 0.044". The star is SAO 127194 = HIP
108428, sp. K0. Also in path: sNY-LI,NYC;sON,Detroit,neIA,SD,sMT.

July 15, Irene: The star is omicron Librae = ZC 2193 = SAO 159191 =
HIP 75118, sp. F5. It has an 8th-mag. companion 24" away in PA 349
deg. that will not be occulted. The path is shown on my map on p.
70 of the March issue of S&T, and there is a note about the event,
but it was inadvertantly left out of the table on p. 72.

July 24: Armenia ang. diam. 0.061". The star is SAO 146999 = HIP
118132, sp. G5. Also in path: swIN,wKY,wGA,wFL,ePeru,neArgentina.

July 30: The star is SAO 160427, spectral type A0.

Aug. 11: Scheila ang. diam. 0.038". The star is Pollux = HIP 37826,
the brightest star predicted to be occulted by an asteroid this year,
but in broad daylight at rather low altitude, so it will be a difficult
observation. Map and information about it are on Denissenko's Web site
at http://hea.iki.rssi.ru/~denis/pic/20050811Sch.gif .

Aug. 13: Julia ang. diam. 0.132". This is the best asteroidal
occultation in North America during 2005, the brightest star
occulted by a large asteroid on the continent. Montana and Sask.
probably have the best chance for clear skies due to the monsoon
that affects the more southern areas in the path in August. The
star is SAO 74880 = HIP 7948, spectral type A2.

Aug. 24: Doris ang. diam. 0.137". The star is SAO 145155, sp. K2.

Aug. 30: Pompeja ang. diam. 0.076"; central duration 65 seconds.

Oct. 19: Rhodope ang. diam. 0.016". The star is Regulus = HIP 49669,
the brightest star to be occulted at night until 2014 March 20, when
Regulus will be occulted by 163 Erigone in Ontario and the n.e. USA.
This year's path is at night in a dark sky over Iberia; with moderate
twilight in s. Italy and strong twilight in Greece; at sunrise in
western Turkey, and in broad daylight east of there. The daylight path
also crosses ne Syria, n. Iraq, Iran, Pakistan, Bengladesh, Myanmar,
Laos, Vietnam, possibly Hainan (se China), and the Philippines.
Observers in the daylight area might set their telescope on a star with
the same declination as Regulus before sunrise, at the right time so
that Regulus will be in the center of the field of view at the time of
the occultation; specific stars and time offsets will be distributed
later. I hope to observe this from Spain with 3 or more recording
systems.

Oct. 31: Euphrosyne ang. diam. 0.165". The star is SAO 147125 = HIP
851, spectral type F5.

Nov. 15: Tercidina ang. diam. 0.068". The 3rd-best-observed
asteroidal occultation was by Tercidina on 2002 Sept. 17, so it
would be good to determine the profile of the asteroid from this
event to help determine its 3-dimensional shape. The star is SAO
145911, spectral type F8.

Nov. 24: The star is SAO 94476 = HIP 24959, spectral type B9.

Dec. 3: Europa ang. diam. 0.113". Strong morning twilight in
Texas. The star is SAO 139619, spectral type G5.

Steve Preston's maps and data for events after May 13 can be found at
http://iota.jhuapl.edu/mpearly.htm , which also includes advance
information for other good events that will occur on July 7, 12, 15,
24,
& 30; Aug. 13, 24, & 30; Oct. 6, 19, & 31; Nov. 15 & 24; and Dec. 3;
summary information and notes about those events will be added in a
future message. For more about the events before May 14, see Steve
Preston's site at http://www.asteroidoccultation.com for updated path
maps, finder charts of different scales, and other details. Also, see
the asteroidal occultation section of the main IOTA site at
http://www.lunar-occultations.com/io...ds/astrndx.htm for
annotated versions of E. Goffin's good finder charts for North American
events and links to sites covering other areas. For Europe, see also
L.
Vasta & J. Manek's site at http://mpocc.astro.cz/mp and J. Schwaenen's
site at http://www.astrosurf.com/eaon (go to his MONTHLY links, for
May and June). New observers can get basic information on timing
occultations at http://iota.jhu/timng920.htm and at
http:/astrosurf.com/eaon/video%20observations.htm .
______

I just list the events in the table above; see the Web sites for
the updated maps to see the closest approach time for your
location, and more accurate coordinates of the star and its
designation. You must display this message with a fixed-space
font such as Courier for the columns of the table to line up.
The U.T. time range is given, with only the minutes of the
hour given for the end time (subtract 60 and add 1 to the hour
for end minutes greater than 59).

Good luck with YOUR observations of asteroidal occultations.
__________________________________________________ _____

3. Below is a first version of the station list for the
occultation by (54) Alexandra on May 17th indicating possible
coverage of the event. If I don't have your station, please
send your location information so that I can include you in another
update either late tonight (Friday night), or tomorrow (Sat.).
Let me know if you plan to observe and aren't so indicated
in the station table below, so I can include you in the next update
to help mobile observers from duplicating your chord. You can
suggest a station from the list, or you can send me your planned
location, if it's not in the list.

Stations for the Alexandra occultation of 2005 May 17

Below is a list of observer stations sorted by distance from
Steve Preston's central line, updated on 2005 May 2. Distances are
given in km measured perpendicularly from the central line. The
time gives the updated time (U.T.) of closest approach (the U.T.
date and local date is 2005 May 17), when the occultation should
occur, within an accuracy of about +/-0.3 minute, at the location.
You only need to monitor the star for an occultation within a
2-minute period centered on the time of closest approach for your
location (to check for occultations by possible satellites of
Alexandra). You can search for your city or name with a word
processor to find your time and distance from the predicted central
line. If your station is not in the list, send me the coordinates
of the place where you plan to observe (in the USA, you can just
specify an address or highway intersection) and I'll add that
station for a later message. Please let me know if you plan to
monitor the star for an occultation, and I will send out a new
version of this list with your track marked as occupied. This will
help for positioning mobile observers. I will put items in the "C"
(code) column, to indicate commitments to observe from fixed sites
and weather probabilities.

NOTE: The table needs to be displayed and/or printed with a fixed-
space font such as Courier for the columns to line up properly, and
with a small font, possibly 8 or 9 point, to prevent line wrapping.
In the e-mail message, the lines are long enough that some (or many)
of the lines will wrap; I will place a .txt (plain ASCII text)
version of this during the afternoon on my Web site at
http://iota.jhuapl.edu . As can be seen from the list, observers
some distance from the path have a chance to see the occultation,
and observers at least within the +/-2-sigma range (distance +320 km
to -320 km S.) are strongly encouraged to attempt observation.
Under C, in the next list I will put * for a committed fixed-site
observer, V = * with video, and m = tentative location for mobile
observer, and M = tentative location for mobile video observer. W =
V or M that will probably be clouded out, while w = * or m that will
probably be clouded out; for these, don't count on their coverage,
but if mobile, try not to set up right at their chord just in case
they get a lucky break in the clouds.

Occultation of SAO 210301 by 54 Alexandra on 2005 May 17;
Distance from center of occultation path - in km
P is the predicted probability that an occultation will occur;
even if it is zero, an occultation by a satellite is possible
U.T. is the time of the occultation predicted for your station;
remember that the disappearance will likely occur at least 0.7 min.
early and that in addition there could be an overall time error of
even 0.5 min. (so start observing at least 1.5 minutes before the
predicted time). The Sun is more than 25 deg. below the horizon at
the time for all observers so the Sun altitude is not given.
