NUMBER:  16723
SUBJECT: Fermi 430148973/MASTER candidate: LCO-Sutherland observations

S. Dichiara, C. Guidorzi (U. Ferrara), D. Kopac (U. Ljubljana)
on behalf of a large collaboration report:

We observed the MASTER OT candidate (Lipunov et al. GCN Circ
16720; Espartero et al. GCN Circ. 16722) with one of the Las
Cumbres Observatory 1-m telescopes in Sutherland (South Africa)
on August 19 at 17:43:02 UT, i.e. ~3.9 hours after the trigger
time (GCN Circ. 16720) with the r',i',z', and Y filters.

At the position of the MASTER OT candidate we found nothing
down to the following limits:

Mid time from  Total Exp   Filter    Magnitude
trigger (hr)   (s)
-------------------------------------------------
4.51           1080        r'        > 20.4
4.57            960        i'        > 19.6

calibrated against nearby USNOB1 stars.
