MASTER II robotic telescope\n(MASTER-Net: http://observ.pereplet.ru) located in Blagoveschensk was\npointed to GRB140629A 15 sec after notice time and 33 sec after\ntrigger time at 2014-06-29 14:18:03.188 UT and found OT in SWIFT\nerror-box. MASTER II Tunka was pointed to GRB140629A 78 sec after\ntrigger time at 2014-06-29 14:18:48.102 UT on the evening twilight sky\n(Sun ~5 d. below horizon) with dark sky observations starting ~ 50 min\nafter trigger time. MASTER II Kislovodsk was pointed to GRB140629A\n~3.2 hours after the trigger directly after the Sun set and weather\nconditions became suitable.\n\nThe preliminary light curve is available here:\nhttp://master.sai.msu.ru/static/GRB/GRB140629A_slope2.png\n\nThe optical transient (Lien et al., GCN 16477; Yurkov et al., GCN\n16478; Moskvitin et al., GCN 16489; Bikmaev et al., GCN 16482; Masi,\nGCN 16483; Maehara, GCN 16484; Malesani et al., GCN 16485; Sonbas et\nal., GCN 16486 etc.) has a maximum at ~ 150 sec. after the burst,\nreaching 13.8 mag, after which it shows a power law decay. The power\nlaw index (alpha) from 200 to 10000 seconds after the trigger is 1.12\n+- 0.1  (F ~ t^-alpha).\n\nThere was no polarization more than 3% discovered on afterglow \nstage.",
