- Аннотация: MASTER-SAAO auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L )discovered OT source at (RA, Dec) = 04h 19m 34.57s -54d 59m 03.4s on 2022-08-23.14338 UT.The OT unfiltered magnitude is 18.0m (mlim=18.2).The OT is seen in 3 images. There is no minor planet at this place.We have >6000 reference unfiltered images in the same photometrical system (MASTER has identical equipment) since 2014-12-27 without previous outbursts registration, for ex.:Date,time(UT) m_lim2022-08-17 04:02:14 17.52022-08-06 03:47:55 18.32018-07-30 02:41:05 20.3(in B filter)2017-01-17 19:32:01 20.02016-12-25 22:24:24 19.92016-09-28 21:24:27 20.02015-02-14 21:32:43 20.0We reobserved it at MASTER-OAFA at 2022-08-23 06:42:28UT (in 3 hours) with mOT=17.9.There is a source with gmag=24.6,rmag=24.2 in VIZIER database (DES data release). This OT is in 222.3"W, 167.3"S from the center of NGC 1566.Spectral observations and photometry are required.The discovery and reference images are available at:http://master.sai.msu.ru/static/OT/041934.57-545903.4.png
