Abstract (from CDS):

GRB 110328A/ Swift J164449.3+573451 (GCNs #11823, #11824) was observed on 31 March 2011 (UT) with the Owens Valley Radio Observatory (OVRO) 40-meter radio telescope (15 GHz center frequency; 3.0 GHz bandwidth; 2.5 GHz noise-equivalent reception bandwidth), at the location of the EVLA counterpart (GCNs #11836, #11848). Two observations were carried out:

<br/> (1) UT 08:48 to 09:10 hours, mean flux density: 2.45 ± 1.14 mJy <br/>

(2) UT 16:02 to 16:59 hours, mean flux density: 5.14 ± 0.84 mJy. <br/><br/>

The 40-meter telescope at OVRO has a Dicke switched receiver; two beams (primary and reference) are used to reduce atmospheric and ground pickup. Possible sources of error are: (i) contaminating radio emission in the reference beam; this will reduce the observed flux density, and (ii) atmospheric transparency variations. Note that during the observations, the weather conditions were favorable.

<br/><br/> More observations of this source with the 40-meter telescope are planned.
