Other Burst Info:

Redshift:

Host Galaxy:

Possible host at z=1.3 (LEGACY catalog)

Other Observatory Detections:

MASTER-OAFA (possible counterpart), Fermi (GBM), AstroSat CZTI

Comments:

Swift's automatic slews are currently disabled, and the burst is Sun constrained until 8th October, so there will be no XRT or UVOT data for this trigger.
