The robotic 60-cm REM telescope located at La Silla (Chile) observed the 
field of the GRB 080130 (Copete et al., GCN 7242). Observations were 
performed in the H-band on Jan 31.3041 (about 0.8 days after the burst ) .

We detect two objects inside the XRT error box (Starling & Stamatikos, 
GCN 7243), both present in the 2MASS catalogue, at the following 
coordinates (J2000):

A) R.A. = 17:26:27.71, Dec. = -53:11:20.3
B) R.A. = 17:26:29.22, Dec. = -53:11:20.3

with an uncertainty of 0.4". The magnitude of both objects seems to be 
consistent with the value reported in the 2MASS catalogue. We note that 
a third 2MASS object is present inside the XRT error box at the 
coordinates (J2000):

C) R.A. = 17:26:28.76, Dec. = -53:11:14.4

but it is below our detection limit. No other sources are visible within 
the XRT error box down to a limiting magnitude of H > 16.1 (3sigma c.l. 
, calibrated against the 2MASS catalogue).

Sources A, B and C are also visible in the DSS image catalogue and seem 
to have a stellar-like profile.
