TITLE: GCN CIRCULAR
NUMBER: 28833
SUBJECT: GRB 201104C: Fermi GBM Final Real-time Localization
DATE: 20/11/04 21:35:03 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely LONG GRB
At 19:23:25 UT on 4 Nov 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 201104C (trigger 626210610.205754 / 201104808).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 240.3, Dec = -36.7 (J2000 degrees, equivalent to J2000 16h 01m, -36d 42'), with a statistical uncertainty of 7.7 degrees.
The angle from the Fermi LAT boresight is 90.0 degrees.
The skymap can be found here:

[GCN OPS NOTE(06Nov20): Due to the uncertainty of the arrival time with respect
to the downtime window (15 hours) of the GCN Circulars processing system,
the error in the date-time in the header of this Circular can be off anywhere from 0-15 hours.]

SUBJECT: GRB 201104C: Swift ToO observations
DATE: 20/11/06 07:51:21 GMT
FROM: Phil Evans at U of Leicester
P. A. Evans (U. Leicester) reports on behalf of the Swift team:
Swift has initiated a ToO observation of the ZTF GRB 201104C.
Automated analysis of the XRT data will be presented online at
https://www.swift.ac.uk/ToO_GRBs/00021039
Any uncatalogued X-ray sources detected in this analysis will be
reported on this website and via GCN COUNTERPART notices. These are
not necessarily related to the ZTF event. Any X-ray source
considered to be a probable afterglow candidate will be reported via a
GCN Circular after manual consideration.
Details of the XRT automated analysis methods are detailed in Evans et
al. (2007, A&A, 469, 379; 2009, MNRAS, 397, 1177 and 2014, ApJS, 210, 8).
This circular is an official product of the Swift-XRT team.

SUBJECT: Correcton to GCN 28848: Swift observes ZTF20acozryr
DATE: 20/11/06 07:58:44 GMT
FROM: Phil Evans at U of Leicester
P.A. Evans reports on behalf of the Swift-XRT team:
GCN CIrcular 28848 incorrectly referred to GRB 201104C. This was due to a software error, not recognising 'ZTF20acozryr’ as a GRB name.
Swift is actually carrying out observations of the source ZTF20acozryr (Coughlin et al., GCN Circ. 28841) which has been possibly associated with GRB 201103B (Svinkin et al., GCN Circl. 28844), and has a redshift of 1.105 (Xu et al., GCN Circl. 28847).
The results of the automated search for an X-ray counterpart consistent with the ZTF position, and analysis of any source(s) found, will appear at the URL previous circulated, i.e.
https://www.swift.ac.uk/ToO_GRBs/00021039
Although the nature of this object has not been confirmed, the zeropoint for any source light curves will be set to the IPN trigger time, in the first instance.
We apologise for the confusion.
