Swift Trigger AXP CXOU J164710.2-455216: MASTER-OAFA observations
Abstract
MASTER robotic telescope ( http://200.123.254.238:49001/ ) located in OAFA was pointed to the GRB170516.3 24 sec after notice time and 34 sec after trigger time at 2017-05-16 07:09:40 UT. On our first (10s exposure) set we haven`t found optical transient within SWIFT error-box (ra=251.825 dec=-45.8942 r=0.05). The 5-sigma upper limit has been about 16.8 mag The observations made on zenit distance = 21 degrees, galaxy latitude b = -1 degree. The moon (76 % bright part) is 65 degrees above the horizon. The distance between moon and object is 45 The sun altitude is -52.6 degree. The object can be observed till sunrise at 2017-05-16 11:18:43 The message may be cited.
