Ramaprakash (CIT) report on behalf of the\nCaltech GRB collaboration:  \"We have obtained a series R- and I-band\nimages of the SAX localization (IAUC 6787) of GRB 971214 using the LRIS\ninstrument on the Keck II 10-m telescope on the nights of Dec 16 and\nDec 17, 1997 UT.  The OT reported by Halpern et al. (IAUC 6788) appears\nto have faded by about 0.5 magnitude with respect to two nearby faint\nstars over a 24-hour interval between UT Dec 16, 1997 and UT Dec 17,\n1997. We note that Diercks et al. (GCN email) report a faster fading\nrate but in the R-band.  We caution our results are preliminary.\nPending a more thorough analysis of the photometry we request that\nthe above photometric information not be cited.\n\nThe OT is very well detected on Dec 16, 1997. The photometric precision\nis 0.7%. The seeing during the first epoch I-band images was ~0.65\narcsec (FWHM) and the OT appears completely consistent with a point\nsource (similar to that of GRB 970508).  Two extended galaxies are\nfound within a radius of 5-arcsecond of the OT. The seeing during the\nsecond epoch is comparbly good.\"",
