- Night Session (3.5 hrs duration). Clear skies, low wind - Session conducted as a Fully Automated Run, in which the Observatory Control Program opened the  Observatory,  built and executed an optimised Observing Plan before finally closing the Observatory at the end of the night (Session was monitored remotely for part of the session just to check that things were proceeding ok and intervene if necessary) - Main aim of the session was to test the Clair 3 Observatory running in Fully Automated Mode for an entire night.  Secondary aim was to acquire images of a selection of targets. - 12" LX200 + ST-10XME for imaging - Ambient Temperature:  12.5°C (minimum) - CCD Temperature:  -15°C (92% av. power) - Notes from 2018-07-25 >>

UV Per - detail Initial thought was that the star was again in outburst based on the catalog position for UV Per in TheSky, but more detailed examination suggest that UV Per is in its normal dim (non-outburst) state (mag +17 or so)

UV Per - Earlier Image, UV Per in Outburst (2014)

CVnet reports that this star is in outburst GCVS Catalog :  Type UGSS, Mag Range +11.0 to +17.5 My original interpretation of the image below "The approximate magnitude in the image below is +9.9 (C) which suggests an outburst". This assumed however that the catalog position for UV Per was correct in TheSky ! (see reassessment below)

Annotated CCD Image (100% size, cropped) 3 x 15 sec exposure (average combine), 3x3 binning, C Filter 2014-11-23 19:46hUT (#571023-29) 12" LX200R  (at f/10.4) + ST-10XME

UV Per - Earlier Image (2014) with Later Re-Assessment

After seeing the recent 2018 image the earlier 2014 image is believed to indeed show UV Per but at outburst at position marked by white indicator, rather than at the catalog position indicated by TheSky6 [ Detailed AAVSO Star Chart for UV Per confirms this correct position]
