Jha (CfA)\nreport:\n\nGiven the microlensing interpretation of GRB000301C (Garnavich, Loeb &\nStanek 2000b: astro-ph/0008049) and the importance of any additional\ndata for this burst, we reduced several additional frames of the\noptical counterpart of GRB000301C obtained with the FLWO 1.2m\ntelescope and UBVI filters on 2000 Mar. 4 (UT).\n\nOur measurements are based on the comparison star A of Garnavich et\nal. (2000a: GCN 573), calibrated by Henden (2000: GCN 583) (magnitudes\ngiven by Jensen et al. 2000: astro-ph/0005609). We obtain the\nfollowing values:\n\n\t  Mar. 4.5097 UT   U=20.89 \\pm 0.13\n\t  Mar. 4.499  UT   B=21.49 \\pm 0.05\n\t  Mar. 4.478  UT   V=20.98 \\pm 0.05\n\t  Mar. 4.485  UT   I=20.28 \\pm 0.07\n\nAs discussed by Garnavich et al. (2000b), to take full advantage of\nthis unique burst a uniform reduction of all CCD data available would\nbe most desired. To encourage such an endeavor, we make all our CCD\ndata (seven 1kx1k frames; see also GCN 573 and 581) publicly available\nthrough the anonymous ftp at\n\nftp://cfa-ftp.harvard.edu/pub/kstanek/GRB000301C/\n\nPlease contact K. Z. Stanek (kstanek@cfa.harvard.edu) if you have any\nquestions concerning the data.\n\nThis message can be cited.",
