Source position is RA= 01 48 25.4 DEC= -77 04 38,\nJ2000, error radius 1' and is consistent with the radio source\nAT J014832.6-770412 reported by Subrahmanyan et al.(GCN 357). \nThis source shows a fading behaviour strongly suggesting we detected the\nX-ray afterglow of GRB990627. \n\nThis message may be cited.\"",
