Petro report for a larger collaboration:\n\nThe field of GRB 000301c was reobserved by the Hubble Space Telescope\nusing the STIS camera in open (50CCD) mode on the 19 April 2000.  The\noptical transient is still visible with an R magnitude of 27.9 +/-\n0.15, where the error is dominated by uncertainties in the calibration\nof STIS and the need to assume the shape of the spectrum across the\nwide bandpass of the detector.   The OT therefore is continuing the\nsteep decline reported in the previous GCN and remains consistent with\nthe late-time power-law reported in Rhoads and Fruchter\n(astro-ph/0004057).\n\nWe find no evidence of a host galaxy underlying the GRB, to a magnitude\nof at least 28.5.   We believe the apparently extended emission\nreported in our previous GCN is due to substantial, and larger than\nexpected, variability in the PSF.   Although we have not yet been able\nto fully reproduce the emission about the point source in our 3\nApril 2000 observations, we suspect this is due to very rapid variability\nin the PSF.  Further analysis of our data has now shown residuals in PSF\nsubtraction comparable in magnitude to that seen in the 3 April observation,\neven when using PSFs from the same star taken in quick succession.",
