Session Notes

NGC 381 - Open Cluster (Herschel VIII-64) NGC 7790 - Open Cluster (Herschel VII-56)     UGC 7534, w/ SN 2018hna - Irregular Galaxy with Type II Supernova     Photometric Monitoring - Variables    - CI Cyg, BL Lac     Astrometric Monitoring - Nearby Stars   - EV Lac, Ross 248 (HH And), Groombridge 34

- Night Session (0.9 hours duration) . Brief clear period within a night of clouds/showers rolling in from North Sea on south-easterly winds. - Main aim of the session was to test routines for inserting a Target of Opportunity into an actively running job queue.      - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature:  4°C (minimum)  - CCD Temperature:  -20°C (78% av. power) - Notes from 2018-10-28 >>

UGC 7534, w/ SN 2018hna  - Irregular Galaxy with Type II Supernova

UGC 7534  w/ SN 2018hna (Ursa Major) Image was acquired as a test of new routines to pick up a 'Target of Opportunity' and insert it into the actively running job queue. A bug prevented the acquisition of the intended image set (3x180s)  but a preceding Locate Frame,  used for centering the target, has however captured the supernova (shown below) The host galaxy (catalog mag +13.8, PGC 40645 ) is too faint to see in this short 10s exposure however the targeted supernova is just visible (shown by the white cross hairs) The bright star in the image is the mag +10.7 star GSC 3840:974 SN 2018hna  (Type II) was discovered  2018/10/22.815 by Koichi Itagaki  Mag at discovery was +16.3 (Rochester Supernova site | Discovery Image | Reference Image | TNS Info ) Image below (2018-10-29.003) was taken 6.2 days after supernova discovery.

Annotated CCD Image (100% size, cropped) 10s exposure (single frame), 3x3 binning, C Filter 2018-10-29 00:04h UT (#634032) 12" LX200R  (at f/10.4) + ST-10XME
