- Аннотация: MASTER-Kislovodsk (Russia) robotic telescope (MASTER-Net: http://observ.pereplet.ru) located in Kislovodsk was pointed to the GRB180224.93 21 sec after notice time and 37 sec after trigger time at 2018-02-24 22:21:44 UT. On our unfiltered polarizing exposures set we found 1 bright optical transient within SWIFT error-box (ra=202.658 dec=38.0878 r=0.05) brighter then 18.1. RA,DEC = 13h 30m 44.057s , +38d 04m 44.55 s Error = 0.1 arcsec maximal magnitute ~ 16.7 The 5-sigma upper limit has been about 18.1mag The message may be cited. ==================================================================== The observations made on zenit distance = 23 degrees, galaxy latitude b = 76 degree. The moon (68 % bright part) is 16 degrees above the horizon. The distance between moon and object is 97 degrees. The sun altitude is -53.0 degree. The object can be observed till sunrise at 2018-02-25 03:53:29 UT. MASTER-SAAO robotic telescope (MASTER-Net: http://observ.pereplet.ru) located in SAAO was pointed to the GRB180224.94 92 sec after notice time and 176 sec after trigger time at 2018-02-24 22:24:12 UT. On our first set we not found optical transient within SWIFT error-box (ra=202.638 dec=38.0819 r=0.1) brighter then 15.8. The 5-sigma upper limit has been about 15.8 mag The message may be cited. The observations made on high zenit distance = 82 degrees, galaxy latitude b = 76 degree. The moon (68 % bright part) is 6 degrees above the horizon. The distance between moon and object is 97 The sun altitude is -48.3 degree. The object can be observed till sunrise at 2018-02-25 04:21:26.
