- Аннотация: MASTER-OAFA robotic telescope (Global MASTER-Net http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy,vol. 2010, 30L) located in Argentina (OAFA observatory of San Juan National University) started inspect of IceCube 190331A error-box (GCN #24028, ATel #12616 (error box center RA,Dec=337.68deg, -20.70deg, Ttrig=2019-03-31 06:55:43.44 UT), also analyzed by Fermi-LAT in GCN #24040, ATel #12619, ATel #12624 and by AGILE in ATel #12623) at 2019-04-01 09:04:32UT with mlim=19.1 (Lipunov et al. GCN #24034). Error-box was reobserved at MASTER-SAAO at 2019-04-02 03:45:33UT with unfiltered mlim=19.2 (observation conditions: error-box_altitude=27 deg, sun_alt=-14deg., Distance to Moon=8 deg!) and at MASTER-OAFA at 2019-04-02 08:32:20UT with unfiltered mlim=19.3m (error-box_altitude=12 deg, Distance to Moon=9 deg!) There are the following sources (Simbad) inside error-box: 4 X-ray sources: 2E 2228.4-2041, [TSA98] J222939.80-205009.91, 1RXS J223015.7-202303, 2E 2229.2-2107; Radio sources: NVSS J223134-203532, PMN J2229-2049, EQ J2229-2054, etc. and Galaxies (without significant current brightness variability): RA,Dec(2000), magnitude, name 22h 31m 38.77s -20d 32m 22.02s 16.37 PGC069066 22h 30m 38.08s -20d 55m 27.17s 16.81 PGC835085 22h 32m 22.83s -20d 30m 17.88s 16.81 PGC069093 22h 30m 23.36s -20d 43m 08.54s 16.87 2MASS22302334-2043081 22h 30m 36.08s -20d 31m 42.76s 16.88 PGC840458 22h 30m 08.90s -20d 45m 06.26s 17.28 PGC837430 22h 31m 04.40s -20d 26m 46.71s 17.47 2MASS22310439-2026465 22h 29m 09.79s -20d 47m 19.16s 17.54 2MASS22290968-2047179 22h 29m 09.53s -20d 47m 14.34s 17.55 2MASS22290968-2047179 22h 31m 03.82s -20d 39m 24.36s 17.65 PGC838697 22h 30m 30.01s -20d 58m 16.05s 17.70 PGC834421 22h 30m 45.20s -20d 41m 18.22s 17.73 PGC838266 22h 31m 13.25s -21d 3m 33.60s 17.77 PGC833229 22h 31m 53.08s -20d 18m 56.56s 17.82 PGC843412 22h 31m 56.78s -20d 29m 41.88s 17.82 PGC840955 22h 32m 34.03s -20d 52m 20.45s 17.82 PGC835844 22h 32m 23.34s -20d 46m 49.29s 17.86 PGC837064 22h 29m 27.14s -20d 27m 27.83s 17.87 PGC841495 22h 32m 12.76s -20d 29m 17.51s 17.90 PGC841050 22h 31m 21.57s -20d 21m 01.18s 18.09 PGC842958 There is NGC 7293 (Helix Nebula) inside IC error-box with 10^4 yrs age http://master.sai.msu.ru/static/IC/MASTERIceCube-190331A.jpg MASTER covermap is available at http://master.sai.msu.ru/static/IC/MASTERIC190331A_cmap.jpg There is no OT, connected with IC alert was found from preliminary analysys, but reduction will be continued. http://www.astronomerstelegram.org/?read=12627
