- Аннотация: MASTER Global Robotic Net (http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) started Fermi GRB 220315A (Fermi GBM team GCN 31758, Ttrigger= 2022-03-15 02:25:56 UT) alert observations at MASTER-OAFA robotic telescope, located in Argentina (OAFA observatory of San Juan National University) 518 sec after notice time (549 sec after trigger time) at 2022-03-15 02:35:05 UT, with upper limit up to 17.8 mag. The observations began at zenith distance = 61 deg. The sun altitude was -44.7 deg. The galactic latitude b = -18 deg.,longitude l = 313 deg. MASTER-SAAO started observations just after sunset at 2022-03-15 17:39:36UT with upper limits 17.0 mag at first image. The observations began at 23deg altitude, the sun altitude was -10deg. Real time updated cover map and OT, that can be discovered, will be available here: https://master.sai.msu.ru/site/master2/observ.php?id=1911047 We obtained the following upper limits at first images Tmid-T0 | Date Time | Site | Coord (J2000) |Filt.| Expt. | Limit| Comment |_ |_ _|_ __| 619 | 2022-03-15 02:35:05 | MASTER-OAFA | (15h 42m 55.34s , -77d 27m 34.1s) | C | 140 | 17.7 | 814 | 2022-03-15 02:38:05 | MASTER-OAFA | (15h 43m 03.16s , -77d 27m 05.3s) | C | 170 | 17.8 | Filter C is a clear (unfiltred) band.
