Source A is at R.A.(2000)= 10h17m53s Dec.(2000)= +71d27'24" Source B is at R.A.(2000)= 10h18m04s Dec.(2000)= +71d33'30" The error radius is 50". Source B does not show substantial variability. Source A shows a rather strong decay during the observation, and is very likely the X-ray afterglow of GB980613 Luigi Piro BeppoSAX Mission Scientist #----------------------------------#------------------------------------------# Luigi Piro | E-mail: Istituto Astrofisica Spaziale | piro@alpha1.ias.rm.cnr.it C.N.R. | SAX program: saxsci@alpha1.ias.rm.cnr.it Via Fosso del Cavaliere | phone: -39-6-4993-4007 I-00133 Roma | phone BeppoSAX center: -39-6-4079-6393 Italy | fax(CNR) : -39-6-20660188 #__________________________________#___________________________________________#
