Upon request of Gary Poyner and Jeremy Shears, I
carried out time series (unfiltered) photometry of
CG Dra (UG), on May 28/29, 2005. The session lasted
for 4.5 hours, and started under good sky
conditions, later followed by cloud fields. CG Dra
was aroud mag 16.0 during most of the run, with
small amplitude modulations of up to 0.15 mag. I
used several period analysis methods of Peranso to
look for periodicities in the data, but could not
identify a stable signal. Hence, I can not confirm
Jeremy Shears' finding of May 27/28
(cvnet-discussion), where he reported a periodic
signal near 91 min.
My CG Dra light curve is depicted below.
