We observed the location of the candidate OT of GRB020305
on 2002  March  13.43  and  14.39  in the K' filter
with the NASA IRTF + NSFCam.
A source is found at the location of the afterglow reported by
Price et al. (GCN 1267) with estimated magnitudes K' = 19.7 and K'=19.8
on March 13.43 and March 14.39 respectively.
The photometric uncertainty is estimated to be 0.2 mag.
For the  star  U0750_07926230 located  7.5 arcsec South  and 12.1 arcsec
East
of the OT we measure a  magnitude K'= 13.53 +/- 0.04.
