Dear group,

One of the most recognized pulsating variable stars is RR Lyrae. Discovered

in 1901, it is used as a "standard candle" for studies involving globular

clusters amongst others.

It fluctuates by almost a full magnitude every 13.60 hours. However, being a

summertime object, it is impossible to pursue a light curve during one

session. With some strategic planning, we can do something over two

all-nighters:

================================================== ==

Perhaps you should record it from both Athens and Anchorage

continuously for a month with some strategic planning. Only

cloud will prevent it, Your colleague in Anchorage can overlap

every 12 hours.

There are no astronomers,there are a lot of astrophotographers who
imagine themselves to be astronomers but in an era where they assert
they can account for a wandering analemma Sun and stellar circumpolar
motion using planetary dynamics,this absolutely excludes the
possibility that astronomers exist presently as a coherent group.There
are a lot of theorists flailing around dumping junk into the celestial
arena and those unfortunate people who follow them but most are
phonies like yourself who imagine that looking through a piece of
magnifying glass qualifies you as an astronomer.

Go buy yourself a microscope where you can do less damage as the last
thing the Greek people need is an idiot undermining their astronomical
heritage -

"Due to the earth's tilt about its axis (23.45°) and its elliptical
orbit about the sun, the location of the sun is not constant from day
to day when observed at the same time on each day over the course of a
full year. Furthermore, this loop will be inclined at different angles
depending on one's geographical latitude. "

http://www.perseus.gr/Astro-Solar-Analemma.htm

You had ample time to correct this stupidity when set off against the
Greek astronomers who defined and distinguished planets from the Sun
and the moon as clearly expressed by Copernicus -

" Moreover, we see the other five planets also retrograde at times,
and stationary at either end [of the regression]. And whereas the sun
always advances along its
own direct path, they wander in various ways, straying sometimes to
the south and sometimes to the north; that is why they are called
"planets" [wanderers]. " Copernicus

Perhaps there are those in the Greek nation who still value their
sovereignty and their heritage but unfortunately you are not one of
them.

Anthony here equates Armstrong's achievement and those who made it
possible with photographing the Sun at clock noon and imagining there
is a sequence of reasoning which explains the figure 8 - there isn't
and some enterprising individuals took it a step further by
discovering the origins of that unfortunate assertion -

"At the end of the article, there is a link to "The Use of the
Analemma — from an inset from Bowles's New and Accurate Map of the
World (1780)". This refers to the (English) meaning of "analemma" in
the 18th century. At that point in time an analemma was an
orthographic projection of the sphere --an entirely distinct
definition (so the link probably doesn't belong here). This "analemma"
could be a carefully drafted drawing or, in fact, a device for
calculation, like a graphical slide rule. These "analemmas" were used
to get approximate solutions to the various problems of spherical
trigonometry. Only after c.1800, globe makers began placing charts of
the Sun's declination on globes and labeling these as analemmas. These
are the origin of the modern usage of the word analemma. Also many of
these early analemmas did not include the graphing of the equation of
time hence they were oval instead of "figure 8" shaped. This is
described well in most early 19th century guides to the "use of
globes". For example in Keith's "New Treatise on the Use of Globes"
published in New York in 1819, you will find
"The analemma is properly an orthographic projection of the sphere on
the plane of the meridian; but what is called the analemma on the
globe, is a narrow slip of paper, the length of which is equal to the
breadth of the torrid zone. It is pasted on some vacant place on the
globe in the torrid zone, and is divided into months, and days of the
months, correspondent to the sun's declination for every day in the
year. It is divided into two parts; the right hand part begins at the
winter solstice, or December 21st, and is reckoned upwards towards the
summer solstice, or June 21st, where the left hand part begins, which
is reckoned downwards in a similar manner, or towards the winter
solstice. On Cary's globes the Analemma somewhat resembles the figure
8. It appears to have been drawn in this shape for the convenience of
showing the equation of time, by means of a straight line which passes
through the middle of it. The equation of time is placed on the
horizon of Rardin's globes."

http://en.wikipedia.org/wiki/Talk:Analemma

It is these silly analemmas which are preventing the reasons why the
equation of time is necessary and what it refers to or perhaps closer
to the truth,the lack of genuine astronomers who can put the
variations in natural noon in context of a moving Earth and none of it
requires declination,it requires only the assumption that daily and
orbital motions are distinct with their own properties.Maybe Anthony
represents his nation in losing their astronomical heritage but I
assume there are Greek people who actually value the clear
distinctions the Greek astronomers once made between the wandering
planets and the non-wandering Sun.

What's your story ?.

Well, M57 is certainly a nebulous object, but M56, being a globular cluster, is not at all nebulous, unless viewed through a very small instrument.

All astronomical objects are best viewed when directly overhead, and with Vega and other delights in the Lyre being located at about 38 to 39 degrees north declination, Alaska would NOT be a superior location from which to view them. Athens, after all is at about 38 degrees north latitude, and Lyra passes essentially directly overhead for Anthony. His problem is that the nights are too short there in the summer to view an entire cycle in one night. In Alaska, the summer nights would be even shorter and RR Lyra would be even farther from Zenith...

Actually something that I am thinking about is the Blazhko effect which is really a propos with RR Lyrae. Any thoughts as to whether it is worth the time to pursue further data surrounding the Blazhko effect? It is not fully understood and, as such, there should be no harm done with additional data.

As for the kind offer involving the use of the remote facilities at Arizona, there is no question it is something I plan to follow-up with very keen interest.

Anthony.
