- Day Time Session, 0.5 hr 
- CCD operation of -5 degC (at 72% average cooling). .
- main objective was to acquire images of sunspot group 956
-  
- Night Time Session, 5.0 hr
- CCD operation of -20 degC (at 78% average cooling). .
- main objective was to acquire test new scripts for monitoring star position & S/N and for performing a guide operation in between image frames, and collect to acquire further baseline images of the exosolar planet host star HAT-P-2
- secondary objective was to acquire images of selected variable stars and nearby stars for photometric and astrometric  monitoring.
- opportunity was taken to take a acquire gallery images of M53, M85, M90, and images of Venus & New Moon.
