collaboration:

"We observed GRB 240825A (Gupta et al., GCN 37274
Not found
 
 
) with the Atacama Large
Millimeter/Submillimeter Array (ALMA) at 97.5 GHz beginning on 2024 August
27 03:22 UT (35.5 h after the burst). ALMA observations of this burst were
delayed due to uninterruptible scheduled Cycle 11 software validation at
the Observatory.

Preliminary analysis reveals a mm source with flux density of ~ 0.3 mJy at
position:
RA (J2000) = 22:58:17.27
Dec (J2000) = +01:01:36.73

with uncertainty ~ 0.07" in each coordinate, consistent with the X-ray
position (Evans et al., GCN 37290
Not found
 
 
) and optical position (Gupta et al., GCN
37274
Not found
 
 
; Jiang et al., GCN 37275

; Dutton et al., GCN 37276

). Further observations are planned.

We thank the JAO staff, AoD, P2G, and the entire ALMA team for their help
with these observations."
