Exoplanet XO-1b in CrB

Dear group ... and oriel,

Good weather and very good seeing are finally here and represent an
opportunity to brush off a serious amount of rust accumulated during
winter and spring due to inactivity thanks to clouds, clouds and more
clouds.

I was somewhat apprehensive in pursuing XO-1b due to the rich presence
of the twelve-day old moon. As was the case with other occasions
involving rich lunar light, I used my Baader IR-Pass filter for the
pursuit of this 180-min transit and the resulting light curve exceeded
my expectations.

The exoplanet XO-1b is very similar to Jupiter with respect to its
mass and radius. Similarly, the host star is also very similar to our
sun with respect to its spectral type, mass and radius.

For the result based on five hours total time and which includes 60
minutes pre-ingress, 180 minutes for the transit itself as well as 65
minutes post-ingress, I kindly direct you to
http://www.perseus.gr/Astro-Photomet...1-20090604.htm and where the
17 mmag drop in the magnitude of the parent star (11.19 pre-ingress)
is beautifully documented.

I would like to thank my two faithful assistants - my AP160 and AP1200
- whose efforts make all of this possible!

Anthony.

Amid great devastation,and the loss visited on astronomy is among the
greatest, there are no proper words to convey it -

I have used 'ground zero' to describe the loss of 3 planetary facts
contained within the 24 hours/360 degrees longitude meridians and the
loss of the retrograde resolution ,losses which makes anything
productive ,where planetary dynamics are involved,impossible and now
you know it.Unlike other times and other human endeavors when great
destruction occurs,there is no authority at the moment to deal with
the magnitude of the astrological errors pouring in over astronomy.

You would find it difficult to feel the loss of the structures such as
timekeeping and structural astronomy in much the same way as some
people feel the hairs on the back of their neck stand up when they see
the twin towers,that type of loss can only come when people have risen
above mediocrity and have seen something that was once a symbol of
pride for our race.

I hardly know what to say anymore,even these few words will be set
upon by people who hardly know what was lost and take dignity and
sometimes sorrow as a weakness.

No need to attach my name anymore,I already told you that in a
previous post.
