- Teegardens Star - attempt (failed due to cloud)
- Evening session (2.4 hrs duration). - Session operated under semi-automated control, with remote monitoring from indoors computer. - Ambient Temperature: +3.0 degC minimum - CCD operation -25 degC (at 68% average cooling). - main objectives of the session were to acquire images selected project stars for ongoing photometric and astrometric analysis. and take follow up image of Nova Delphini 2013 -
| Nova Delphini 2013 (Delphinus) Nova Delphini was discovered on 14th August 2013 by Japanese observer Koichi Itagaki at magnitude +6.8. Koichi had imaged the same field the day before and nothing was visible at the same location. The progenitor star was identified from archive images as being magnitude +16.9 The image below was taken 59 days after discovery when
nova had faded to around +9.5 |
