Suarez-Andres The Instituto de Astrofisica de Canarias MASTER II robotic telescope (MASTER-Net: http://observ.pereplet.ru) located in OAFA was pointed to the possible grb's Swift Trigger 748858 17 sec after notice time and 93 sec after trigger time at 2017-04-19 07:45:09 UT. On our first (20s exposure) set we haven`t found optical transient within SWIFT error-box (ra=199.85 dec=15.4703 r=0.05) (M. H. Siegel et al. GCN 21011). The 5-sigma upper limit has been about 18.7 mag Maximal limit of coadded images starting at 2017-04-19 07:45:09 (93 s after trigger time, 5000s exposure) is 19.7 mag. The observations made on zenit distance = 71 degrees, galaxy latitude b = 76 degree. The moon (51 % bright part) is 47 degrees above the horizon. The distance between moon and object is 104 The sun altitude is -41.8 degree. The object observed till 2017-04-19 09:29:17 The message may be cited.
