  T. N. Ukwatta (MSU), D. N. Burrows (PSU), J. R. Cummings (NASA/UMBC), N. Gehrels (NASA/GSFC), J. A. Kennea (PSU), D. Kocevski (NASA/GSFC/ORAU), H. A. Krimm (CRESST/GSFC/USRA), K. L. Page (U Leicester) and T. Sakamoto (AGU) report on behalf of the Swift Team:
  At 19:09:32 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 130930A (trigger=572489). The BAT on-board calculated location is RA, Dec 190.661, -35.502 which is

     RA(J2000) = 12h 42m 39s
     Dec(J2000) = -35d 30' 08"
  

  with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). As is usual with image triggers, the BAT light curve showed no significant structure.
  Due to a Sun observing constraint, Swift cannot slew to the BAT position until 03:51 UT on 2013 November 26. There will thus be no XRT or UVOT data for this trigger before this time.
  Burst Advocate for this burst is T. N. Ukwatta (tilan.ukwatta AT gmail.com). Please contact the BA by email if you require additional information regarding Swift followup of this burst. In extremely urgent cases, after trying the Burst Advocate, you can contact the Swift PI by phone (see Swift TOO web site for information: http://www.swift.psu.edu/too.html.)
