TITLE:   GCN CIRCULAR
NUMBER:  6893
SUBJECT: GRB 071010B: Super-LOTIS upper limit
DATE:    07/10/11 20:35:13 GMT
FROM:    Adria C. Updike at Clemson U  <aupdike at clemson.edu>

A. C. Updike (Clemson), P. A. Milne (Steward Observatory), G. G. Williams
(MMTO), and D. H. Hartmann (Clemson) report on behalf
of the Super-LOTIS Collaboration:

The robotic 0.6m Super-LOTIS telescope observed the field of GRB 071010B
(GCN 6871, Markwardt et al.) beginning at 10:24 UT on Oct 11, 13.6 hours
 after the trigger.  We obtained 59 minutes in the R band
and 19 minutes in the V band.  We do not detect the OT (Oksanen GCN
6873, Kann et al. GCN 6884) in the stacked exposures.  Limiting
magnitudes were determined using 10 field stars calibrated to the USNO
B1.0 catalog.
