D. A. Kann (TLS Tautenburg) reports:
At the position of the possible X-ray afterglow (Troja, Page &
McBreen, GCN 6255) of the short GRB 070406 (Cummings et
al., GCN 6247), there is a bright galaxy (at least, it is flagged as
such) detected in the SDSS at position (J2000):
RA = 13:15:51.6
Dec = +16:30:48.31
This is 3".75 away in RA and 1".41 in Dec. and thus within the
error circle.
The (model) magnitudes are:
u' = 20.017 +/- 0.050
b' = 19.775 +/- 0.016
v' = 19.720 +/- 0.019
r' = 19.630 +/- 0.025
i' = 19.510 +/- 0.078
It is thus quite blue. Further X-ray observations should show if
this is possibly only an AGN.
Spectroscopy of this galaxy is strongly encouraged.
