We observed the field of GRB 100213B detected by Swift
(trigger #412220; Vetere et al., GCN Circ. 10412) with the 14-inch
Goddard Robotic Telescope (GRT) located at the Goddard Geophysical
and Astronomical Observatory (http://cddisa.gsfc.nasa.gov/ggao/).
Total 59 images of 60 sec exposures were taken in the R filter
starting from February 13 23:55:15 (UT) about 0.94 hours after
the trigger and stopped on February 14 01:50:46 (UT). We do
not detect the optical afterglow both in the individual images
and the combined image inside the XRT position (Evans, GCN #10423).
The estimated three sigma upper limit of the combined image
(total exposure of 3540 sec) is ~18.7 mag using the USNO-B1 catalog.
