Astrometric Monitoring - Nearby Stars - None
- Evening session (3.5 hrs duration). - Session operated under semi-automated control, with remote monitoring from indoors computer.
(Power-Line networking)- Ambient Temperature: -1.0 deg C (minimum) . Dew inside corrector plate. - CCD operation -25 degC (at 59% average cooling). - main objectives of the session were to acquire images of a number of comets and selected project stars for ongoing photometric analysis. -

An attempt to image the Comet P/1998 U3 (Jager) was unsuccessful. Comet was expected at mag+15.9 but there was no sign on comet down to mag +18) . Image did however capture the galaxy PGC 1675230 at estimated mag +16.
