Sbarufatti (INAF-OAB/PSU) report on behalf of the Swift Team:\n\nAt 06:08:32 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated 4U 1850-03 (trigger=666827).  Swift did not slew due to observing constraint. \nThe BAT on-board calculated location is \nRA, Dec 282.088, -2.421, which is \n   RA(J2000)  =  18h 48m 21s\n   Dec(J2000) = -02d 25' 16\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  As is typical for image triggers, nothing is visible\nin the real-time TDRSS light curve. \n\nDue to a Sun observing constraint, Swift cannot slew to the BAT\nposition until 10:55 UT on 2016 February 15. There will thus be no XRT\nor UVOT data for this trigger before this time.",
