GRB 210619B: ALMA detection
Abstract
"We observed GRB 210619B (D'Avanzo et al. GCN 30261) with the Atacama Large Millimeter/Submillimeter Array (ALMA) at 97.5 GHz beginning on 2021 June 25 06:53:48 UT (5.29 days after the burst). ALMA observations of this burst were delayed due to a major snowstorm at the array. Preliminary analysis reveals a mm source with flux density of ~ 0.1 mJy at position: RA (J2000) = 21:18:52.349 (+/- 0.002) Dec (J2000) = +33:51:01.40 (+/- 0.04) consistent with the X-ray position (Beardmore et al. GCN 30267) and optical position (D'Avanzo et al., GCN 30261; Kuin et al. GCN 30278). We thank the JAO staff, AoD, P2G, and the entire ALMA team for their help with these observations."
