The 5-sigma upper limit on our first (180s exposure) set is about 18.73mag MASTER II robotic telescope located in Kislovodsk was starting survey on the FERMI GRB140825.33 error-box (ra=22 51 21 dec=+31 05 24 r=2.660000) 29715 sec after notice time and 33543 sec after trigger time at 2014-08-25 17:11:49 UT. The 5-sigma upper limit on our first (180s exposure) set is about 18.86mag MASTER-Tunka auto-detection system discovered MASTER OT J230448.20+324534.1 at (RA, Dec) = 23h 04m 48.20s +32d 45m 34.1s on 2014-08-25.62245 UT. The OT unfiltered magnitude is 18.6m (limit 19.9m). The OT is seen in 2 images. There is no minor planet at this place. THere is SDSS9 J230447.99+324540.9 galaxy (Rmag = 22) with 7.3 arcsec offset. We have reference image without OT on 2013-08-30.62251 UT with unfiltered magnitude limit 19.9m. Spectral observations are required.
