(Berkeley), C. G. Mundell (University of Bath), and P. Schady (University
of Bath) report on behalf of a larger collaboration:
"We observed GRB 210905A (Sonbas et al. GCN 30765) with the Atacama Large
Millimeter/Submillimeter Array (ALMA) at 97.5 GHz beginning on 2021
September 05 23:41 UT (0.98 days after the burst).
Preliminary analysis reveals a mm source with flux density of ~ 0.1 mJy at
position:
RA (J2000) = 20:36:11.5685 (+/- 0.0002)
Dec (J2000) = -44:26:24.840 (+/- 0.002)
consistent with the X-ray position (Beardmore et al., GCN 30768) and
optical position (Strausbaugh & Cucchiara, GCN 30769).
We thank the JAO staff, AoD, P2G, and the entire ALMA team for their help
with these observations."
