Axelrod (Arizona) report:\n\nWe have observed the error box of GRB 020418 (GCN #1376) with the robotic\nMSO 50-inch telescope + MACHO imager at 2002 Apr 19.42 UT (approximately\n25.5 hours after the GRB) with 3 x 300 sec exposures.  The combined image\ncovers the entire error box down to a limiting magnitude of R ~ 21.1 mag,\nbased on comparison with USNO-A2.0 magnitudes.  We do not find any\nconvincing afterglow candidate upon visual comparison with the second\nDigitised Sky Survey down to the plate limit, R ~ 20.5 mag.\n\nFurther observations are planned.\n\nThis message may be cited.",
