P. A. Milne (Steward Observatory) and G. G. Williams (MMTO), on behalf
of the Super-LOTIS Collaboration, report:
The robotic 0.6-m Super-LOTIS telescope began observing the error box
of GRB 080319B (Swift Trigger 306757, Racusin et al. GCN 7427) at
06:27:00.3 UT, 851 seconds after the trigger. We identify a bright
source consistent within the UVOT candidate.
Using the USNO-B1.0 star (1263-0223138) at RA=14:31:39.66,
Dec=+36:18:54.5 with R2MAG=14.98 as a reference, we estimate the
following R-band magnitude for the transient:
t_start (UT) exp t (s) t_start-t_0 (s) R Mag
----------------------------------------------------------------
06:27:00.3 60 851 R = 13.52 +/- 0.01
Additional observations and analysis are ongoing.
