MASTER II  robotic telescope (MASTER-Net: http://observ.pereplet.ru) 
located in Tunka was starting survey on the FERMI  GRB140824.61 error-box 
(ra=01 13 19 dec=+58 38 24 r=1.490000)  7913 sec after notice time and 
9534 sec after trigger time at 2014-08-24 17:12:06 UT. The 5-sigma upper 
limit on our first (180s exposure)  set is about 19.1 mag (unfiltered)

MASTER-Tunka auto-detection system discovered
MASTER OT JR011101.13+603337.5 source at:

  (RA, Dec) = 01h 11m 01.13s +60d 33m 37.5s on 2014-08-24.71962 UT.
The OT unfiltered magnitude is 17.0m (limit 19.5m).

The OT is seen in 16 images. There is no minor planet at this place.

We have reference image without OT on 2013-06-18.75418 UT with unfiltered 
magnitude limit 19.1m.
Follow up observations  are required.

The discovery and reference images are available at:
