M. De Pasquale (UNLV), D. Gruber (MPE), J. M. Burgess (UAH), J. McEnery
(NASA/GSFC), S. T. Holland (STSCI), S. Razzaque (GMU/NRL) and J. L.
Racusin (NASA/GSFC), on behalf of the Swift, Fermi-GBM, and the Fermi-LAT
teams:
GRB 120624B, detected by Fermi-GBM (GCN 13377), Fermi-LAT (GCN 13379),
Swift-BAT (GCN 13381), and Konus-Wind (GCN 13382) has very high fluence
(1.9e-04 erg cm-2) and peak flux. The fluence of GRB 120624B in among the
top 1.5% of bursts detected by Swift-BAT and the top 0.55% detected by
Fermi-GBM.
The GRB position is unfortunately within the Swift Moon constraint.
Swift-XRT/-UVOT follow-up observations are planned when if comes out of
Moon constraint on June 27.4.
The refined BAT localization (GCN 13384) has an error radius of 1 arcmin
(90% containment). There are 13 SDSS galaxies with r>24 within the BAT
error circle. Analysis of the prompt emission suggests that the redshift
of this event is z > ~0.3 if this burst obeys the Amati relation, with
E_iso > ~4e+52 erg.
We strongly encourage follow-up observations of GRB 120624B.
