Neutral Hydrogen Observations of GRB 030329

Target of opp ortunity observations are requested to measure the neutral hydrogen sp ectrum in absorption against the Gamma-Ray Burst (GRB) 030329. At the redshifted HI frequency of 1215 MHz, the GRB afterglow has a flux density of 3.5 mJy as of Octob er 2003, but is fading. Detection of HI in absorption would provide imp ortant information on the fileball mo del of GRBs. We intend to also observe the mainlines of the OH molecule to lo ok for the presence of absorption or maser emission.

1209-1229 MHz 1423-1435 MHz We request Punta Salinas to operate in their MODE C

This proposal requires coordination with Punta Salinas radar within the band 1222-1381 MHz.. This proposal requires coordination with GPS L3 at 1381 MHz.
