LIGO/Virgo/KAGRA S230521k: MASTER new OT discovery
Abstract
MASTER OT J071612.28-415537.5 discovery During LVC S230521k https://gcn.gsfc.nasa.gov/notices_l/S230521k.lvc inspection survey (Lipunov et al. GCN 33849) MASTER-SAAO auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L ) discovered OT source at (R.A.,Dec.2000) = 07h 16m 12.28s -41d 55m 37.5s on 2023-05-23.71558 UT. The OT unfiltered magnitude is 18.2m (mlim=19.0). The OT is seen in 4 images. There is no minor planet at this place. We have reference images on 2021-02-16 02:18:16UT with mlim=19.5, on 2014-12-24.97843 UT with unfiltered mlim=19.7m and other, there is no outbursts at automatic light curve, but analysis of archive images will be continued. Spectral observations and deep photometry are required. Observations and analysis will be continued.
