Axelrod (Arizona) report:\n\nWe have re-observed the error box of GRB 020418 (GCN #1376) with the\nrobotic MSO 50-inch telescope + MACHO imager at 2002 Apr 20.41 UT to\nsearch for variable sources that might be the afterglow.  On PSF-matched\nimage subtraction from our first epoch image (GCN #1377), we do not find\nany afterglow candidate to the limiting magnitude of our first epoch\nimages (R ~ 21.2 mag).\n\nThis message may be cited.",
