larger GRB follow up collaboration report:
We observed the error box of GRB060714 (Krimm et al., GCN5311) with 1.5 m
telescope of Maidanak Astronomical Observatory (MAO) on July 14, (UT)
16:14 - 17:29. A set of 120 s exposures were taken in R and B bands. The
afterglow (Krimm et al., GCN5311) is clearly detected in single R-images and
marginally detected in single images in B. A photometry of the afterglow
based on USNO A2.0 is following:
Mid time T0+ (d), Exposure (s), Filter, Mag.
0.0446676 1x120 R 18.70 0.07
0.0484408 1x120 R 18.63 0.06
0.0522834 1x120 R 18.77 0.07
0.0560218 1x120 R 18.88 0.07
0.0598528 1x120 R 18.91 0.07
0.0655589 2x120 R 18.86 0.06
0.0762707 3x120 R 18.87 0.07
0.0896677 3x120 R 18.82 0.07
0.0708077 14x120 B 19.87 0.04
Taking into account early Swift/UVOT observations (Boyd et al., GCN5357)
one can suggest that during our observations the afterglow re-brightening
took place.
