TITLE: GCN CIRCULAR
NUMBER: 30635
SUBJECT: GRB 210812B: Fermi GBM Final Real-time Localization
DATE: 21/08/12 18:21:09 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely LONG GRB
At 00:15:51 UT on 12 Aug 2021, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 210812B (trigger 650420156.733782 / 210812011).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 183.7, Dec = 2.4 (J2000 degrees, equivalent to J2000 12h 14m, 2d 23'), with a statistical uncertainty of 6.3 degrees.
The angle from the Fermi LAT boresight is 29.0 degrees.

SUBJECT: Retraction of Fermi GBM GCN 30630 and GCN 30632
DATE: 21/08/12 21:43:37 GMT
FROM: Peter Veres at UAH
The Fermi GBM Team reports:
"
Due to a data processing error, the names of two GRBs localized by Fermi
GBM were incorrectly reported in GCN 30630 and GCN 30632.
The error was corrected and the final real-time localizations of these GRBs
were re-sent in two new GCNs. The correction for GCN 30630 was sent as GCN
30635 with the name GRB 210812B. The correction for GCN 30632 was sent as
GCN 30633 with the name GRB 210812A.
We apologize for any confusion this may have caused."
