MASTER II robotic telescope (MASTER-Net: http://observ.pereplet.ru)
located in Kislovodsk was pointed to the GRB131024B 27 sec s after notice
time and 36 sec after GRB time at 2013-10-24T21-36-07.864 UT. On our first
(10s exposure) set we haven`t found optical transient within SWIFT
error-box (Krimm et. al GCN15371).
The 5-sigma upper limit has been about 17.2 mag.
This is the prompt observations becaus GRB duration time T_90 = 64+-22 sec
(Baumgartner et al., GCN Baumgartner).
Such long circular delay was due to with daily power cut on observatory.
The message may be cited.
