AAVSO Special Notice #149 asks for observation of a suspected eclipsing
polar,  see

<http://www.aavso.org/publications/specialnotice/149.shtml>

so I thought I would try it.  Last night on a three hour run of 20 second,
unfiltered images I was watching the images pop in every 25 seconds or so.
Suddenly I noticed the target star was fading and over about 8-10 exposures,
it faded out of sight (at least at the display settings in my computer at
the time).  I was looking forward to watching it re-emerge but from one
image where it wasn't visible to the next it reappeared at "full" strength.
Checking my measurements later, the star brightened just over 3 mags in
under 25 seconds.  I found it very exciting.  There is also a repeatable dip
of about 1 mag just before the big dip (>5 mags)(also visible in Arto's
data).  I got two of the eclipses in my three hour run.  Interesting star!
