Johnston report:\n\nWe have observed the improved HETE error circle for GRB020127 (= H1902)\n(GCN 1229) using the ARC 3.5-m telescope at APO under excellent seeing\nconditions but a very bright moon on 2002 January 28 beginning at UT\n01:38 (4.43 hours after the GRB).  A series of images covering an area\nsomewhat larger than the entire improved HETE error circle was acquired\nin SDSS r' and i' filters.\n\nVisual inspection of the series of r' and i' images reveals no new\nobject brighter than the DSS limiting magnitude for this field (R ~\n19.5).\n\nThis message is quotable.\n\n[GCN OPS NOTE (28Jan02):  See errata notice in GCN# 1231.]",
