Klingler (PSU)\nreport on behalf of the Neil Gehrels Swift Observatory Team:\n\nSwift BAT triggered on GRB 210410A, previously reported by Fermi/GBM (GCN #29777). \nDue to a telemetry drop-out, no prompt BAT data are available, however XRT has \nlocalized the source. \n\nUsing promptly downlinked data we find an uncatalogued X-ray source\nlocated at RA, Dec 269.75417, 45.36339 which is equivalent to:\n   RA(J2000)  = 17h 59m 01.00s\n   Dec(J2000) = +45d 21' 48.2\"\nwith an uncertainty of 6.1 arcseconds (radius, 90% containment). This\nposition may be improved as more data are received; the latest position\nis available at https://www.swift.ac.uk/sper. No spectrum from the\npromptly downlinked event data is yet available to determine the column\ndensity. \n\nBurst Advocate for this burst is A. Melandri (andrea.melandri AT brera.inaf.it). \nPlease contact the BA by email if you require additional information\nregarding Swift followup of this burst. In extremely urgent cases, after\ntrying the Burst Advocate, you can contact the Swift PI by phone (see\nSwift TOO web site for information: http://www.swift.psu.edu/)",
