Berger (Harvard University), R. Chornock (UC Berkeley), W. Fong (Northwestern University), R. Margutti (UC Berkeley), and P. Schady (University of Bath) report on behalf of a larger collaboration:

“We observed GRB 240825A (Gupta et al., GCN 37274
Not found
 
 
) with the Very Large Array (VLA) at multiple frequencies beginning on 2024 August 27 at 07:10 UT (39.3 hours post burst). 

In preliminary analysis, we detect the radio counterpart (Laskar et al., GCN 37314
Not found
 
 
) at 8.6 GHz with a flux density of F ~ 0.3mJy at the position:
RA(J2000) = 22:58:17.27 +/- 0.01”
Dec(J2000) = +01:01:36.78 +/- 0.02”

This is consistent with the X-ray position (Evans et al., GCN 37290
Not found
 
 
), optical position (Gupta et al., GCN 37274

; Jiang et al., GCN 37275

), and radio position (Laskar et al., GCN 37314

). Further observations are planned. 

We thank the VLA staff for scheduling and executing these observations.”
