GRB 970228
Near-Infrared follow-up Observations
In IAU Circular 6611 we write:
"The error box of GRB 970228 was surveyed with
the Calar Alto 3.5-m telescope (f/10) on Mar. 17.8 UT using the
near-infrared camera MAGIC (0".81 pixels, seeing < 1".5,
photometric sky). At the position of the optical transient
reported on IAUC 6584, a source is detected (5 sigma) in the J band
(magnitudes J = 21.0, H > 20.0, K > 19.5). We cannot decide,
however, whether this is the reported underlying galaxy (Groot et
al. and Metzger et al., IAUC 6588) or the fading infrared
counterpart of the optical transient (or both)."
The following figure supplements this message.
Figure 1: GRB 970228 error box. J-band image taken on 1997, March 17.8 UT.
Calar Alto, DSAZ, Spain. 3.5-m telescope.
MAGIC, wide-field mode (f/10). The image size is approximately 2 arcmin x 2 arcmin.
North is up, east is left.
The marked area approximately corresponds to the published
HST image.
