R. Ricci (U Rome), E. Troja (U Rome) report on behalf of a larger collaboration:

We observed the GRB 250221A discovered by Swift/BAT (Caputo et al. GCN 39396) with 
the Very Large Array at the centre frequency of 10 GHz (X-band) with a bandwidth of 4 GHz 
at a mid time of 1.95 days after the trigger. 

A weak source is detected at the target position with a flux density of 63 +/- 9 microJy. 

Further observations are planned to assess its variability. 

We thank the VLA staff for promptly executing the observations.
