Comments:

BAT: The current analysis of the BAT data does not allow us to distinguish between the interpretations of this event as either a GRB or galactic transient.
XRT: It is likely that BAT trigger 565651 was a somewhat unusual GRB rather than a Galactic or extragalactic transient, in spite of its proximity to the Galactic center.
UVOT: no detection
