P. B. Cameron (Caltech) and S. R. Kulkarni (Caltech) report:
"We observed the position of SGR 1806-20 with the Very Large Array (VLA)
in
A-configuration on 2005
Jan 3.81 UT (t ~ 6.9 days after the giant flare, GCN #2920). We detect a
radio source coincident with the X-ray position reported by
Kaplan et al. (2002, ApJ, 564, 935) at the approximate freqeucnies
and flux densities
listed below.
Freq (GHz) Flux density (mJy)
--------------------------------
4.86 73
8.46 41
This is a factor of brighter of 100 times brighter at 8.46 GHz than SGR
1900+14 at peak. Further observations are planned.
