GCN Circular 1246

GRB020127, WSRT radio observations

Evert Rol, Paul Vreeswijk, Lex Kaper, (University of Amsterdam), Richard
Strom (ASTRON, UoA) report, on behalf of a larger collaboration:

"We have performed observations of the HETE error circle of GRB020127
(Ricker et al, GCN 1229
Not found
 
 
) with the Westerbork Synthesis Radio
Telescope. We observed at 2.3 GHz at two epochs, Jan 28.72-29.22 and
Feb 3.71-4.21, and at 1.4 GHz at one epoch, Jan 28.72-29.22.

At 2.3 GHz, we detect six sources within the combined HETE/IPN error
circle (Hurley et al., GCN 1232
Not found
 
 
) to a limit of 0.62 mJy (3 sigma). No
sources show variability between the two observations. The 1.4 GHz
observation also contains these six sources, none of which has a
positive spectral index.

We do not find any radio counterparts to the Chandra X-ray sources
(Fox, GCN 1241
