- Evening session (5.6 hrs), clear, cold with light frost
- Session operated under semi-automated control, with remote monitoring from indoors computer. 
- Ambient Temperature:  -2 deg C  (minimum)
- CCD operation -25 degC (at 55% average cooling).  
- main objectives of the session was to acquire images of selected project stars for ongoing photometric and astrometric analysis
- opportunity taken to acquire several deep sky targets
- Flats Frame sets through different filters taken on 2010-03-10 using new Light Board (-20 degC CCD Temp)
- Notes from 2010-03-09

GK Per - Variable Star, Nova (1901) : Outburst Mar 2010 

GK Per (Perseus) 
GK Per is star (NA + XP) which had a nova eruption in 1901, and  undergoes occasional 
minor outbursts since then,  for example the outburst in Sept 2008.

New outburst in Mar 2010 is noted to have occurred between observations 
at 2010-03-01 01:00h UT and 2010-03-09 20:00h UT
