Dear group,
Finally an opportunity this past Monday for some work following a
three-month hiatus due to bad weather. I used the opportunity to
pursue the exoplanet transit for HAT-P-22b in UMa. This discovery was
announced about 18 months ago and involves a somewhat massive hot
Jupiter.
Humidity was significant and especially during the latter portion of
the session where it became grotesque (my AP RHA was soaked). For the
result from the 4.6-hr session, please see

Also in the same field of view is the pulsating variable CzeV218 and
which I had originally failed to identify in various databases
(including AAVSO), thus leading me to think that I may have
accidently stumbled upon a new discovery. However, once the radius
was (properly) expanded for possible variables around HAT-P-22, this
delta Scuti was picked up in the AAVSO database. It seems to have
been discovered just after the announcement for HAT-P-22 eighteen
months ago and probably represents an accidental find during
photometry analysis of HAT-P-22 (similar to my case on Monday). For a
result based on 5.2 hrs of data for this pulsating variable whose
magnitude changes by 0.04 mag over 119.52 minutes, please see

Thank you, Anthony! Hope your weather continues to improve.
