D. A. Perley and J. S. Bloom report on behalf of the GRAASP collaboration:
Using Gemini-South (+GMOS), we obtained 2x60 seconds of imaging in g and
and 1x60 seconds in r of NGC 2770 as acquisition images in preparation
for later spectroscopic observations. The sequence started at UT 05:33
2008-01-11, 40.00 hours after the trigger time derived by Modjaz et al.
(GCN 7175). Calibrating relative to the Sloan Digital Sky Survey, we
measure the following magnitudes for XRF 080109 / SN 2008D (Berger &
Soderberg, GCN 7159; Kong & Marcone, ATEL 1355) at this time:
g = 18.72 +/- 0.15
r = 18.10 +/- 0.07
For SN 2007uy, we derive g = 16.31 +/- 0.15, r = 15.86 +/- 0.07.
