GRB 200714E

The Fermi GBM team reports the detection of a likely LONG GRB

At 18:35:05 UT on 14 Jul 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 200714E (trigger 616444510.078062 / 200714774).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 215.8, Dec = -49.7 (J2000 degrees, equivalent to J2000 14h 23m, -49d 42'), with a statistical uncertainty of 1.1 degrees.

The angle from the Fermi LAT boresight is 92.0 degrees.

B. Biltzinger, F. Kunzweiler, F. Berlato, J. Burgess & J. Greiner (all MPE Garching) report:

The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger
616444510 at 18:35:05 on 14 July 2020 were automatically fitted for spectrum
and sky location with BALROG (Burgess et al. 2018, MNRAS 476, 1427;
Berlato et al. 2019, ApJ 873, 60).

The best-fit position (1 sigma statistical errors) is:

RA(2000.0) = 194.8+/-2.2 deg
Decl.(2000.0) = -52.4+/-1.8 deg

We estimate an additional systematic error of 2 deg.

Aaron Tohuvavohu (U Toronto), James DeLaunay (PSU), Jamie Kennea (PSU) report:

Swift/BAT did not trigger on GRB 200714E (T0: 2020-07-14 18:35:05 UTC,
Fermi/GBM Team GCN 28098
Loading...
 
 ) due to a slew.

The Fermi/GBM notice, distributed at T0+6 seconds triggered the Swift
Mission Operations Center operated Gamma-ray Urgent Archiver for Novel
Opportunities (GUANO; Tohuvavohu et al. 2020, arXiv: 2005.01751).

Upon trigger by this notice, GUANO sent a command to the Swift Burst
Alert Telescope (BAT) to save 200 seconds of BAT event-mode data from
[-50,+150] seconds around the time of the burst. All the requested
event mode data was delivered to the ground.

Using the normal BAT imaging technique, we find the location of the
GRB with an SNR of 11.5.

The BAT ground-calculated position is
RA, Dec = 196.8656, -51.6403 deg which is
   RA(J2000)  = 13h 7m 27.7s
   Dec(J2000) =  -51d 38' 25"
with an uncertainty of 5 arcmin, (radius, sys+stat, 90% containment).
The partial coding was 28.9%.

This position is consistent with the Fermi GBM localization (GCN
28098
Loading...
 
 ) and the BALROG localization (GCN 28099
Loading...
 
 ).

XRT and UVOT follow-up has been triggered. Results of follow-up
observations will be reported in future circulars.

GUANO is a fully autonomous, extremely low latency, spacecraft
commanding pipeline designed for targeted recovery of BAT event mode
data around the times of compelling astrophysical events to enable
more sensitive GRB searches.

A live reporting of Swift/BAT event data recovered by GUANO can be
found at: https://www.swift.psu.edu/guano/

P. A. Evans (U. Leicester) reports on behalf of the Swift team:

Swift has initiated a ToO observation of the Swift/BAT GRB 200714E. 
Automated analysis of the XRT data will be presented online at
https://www.swift.ac.uk/ToO_GRBs/00021017

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 Swift/BAT 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).

Swift-XRT has performed follow-up observations of the Fermi-GBM and
Swift/BAT (GUANO)-detected burst GRB 200714E (GCN Circs. 28098

  and
28103

 ), collecting 2.2 ks of Photon Counting (PC) mode data between
T0+37.3 ks and T0+44.5 ks. 

One uncatalogued X-ray source has been detected, it is below the RASS
limit and shows no definitive signs of fading. Therefore, at the
present time we cannot confirm this as the afterglow. Details of this
source are given below:

Source 1:
  RA (J2000.0):  196.8225  =  13:07:17.41
  Dec (J2000.0): -51.6390  =  -51:38:20.4
  Error: 3.1 arcsec (radius, 90% conf. [Enhanced position])
  Count-rate: 0.0138 +/- 0.0033 ct s^-1   
  Distance: 96 arcsec from Swift/BAT position.
  Flux: (6.2 +/- 1.5)e-13 erg cm^-2 s^-1 (observed, 0.3-10 keV)

The results of the XRT-team automatic analysis of the XRT observations,
including a position-specific upper limit calculator, are available at

Further observations are planned.

"At 18:35:05.08 UT on 14 July 2020, the Fermi Gamma-Ray Burst Monitor (GBM)
triggered and located GRB 200714E (trigger 616444510 / 200714774), which was also
detected by the Swift/BAT-GUANO (Tohuvavohu et al. 2020, GCN 28103
Loading...
 
 ). The Fermi GBM
Final Real-time Localization (GCN 28098
Loading...
 
 ) is consistent with the Swift position.

The angle from the Fermi LAT boresight at the GBM trigger time is 104 degrees.

The GBM light curve shows a single bright peak
with a duration (T90) of about 20 s (50-300 keV).
The time-averaged spectrum from T0+0.8 s to T0+21.3 s is
best fit by a Band function with Epeak = 189 +/- 28 keV,
alpha = -0.92 +/- 0.09, and beta = -2.3 +/- 0.3.

The event fluence (10-1000 keV) in this time interval is
(9.4 +/- 0.5)E-06 erg/cm^2. The 1-sec peak photon flux measured
starting from T0+3.4 s in the 10-1000 keV band
is 11.1 +/- 0.4 ph/s/cm^2.

The spectral analysis results presented above are preliminary;
final results will be published in the GBM GRB Catalog:

Swift-XRT has conducted further observations of the field of the
Swift/BAT-GUANO-detected burst GRB 200714E (Tohuvavohu et al. GCN Circ.
28103
Loading...
 
 ). The observations now extend from T0+37.4 ks to T0+578.8 ks. The
source previously reported by D'Elia et al. (GCN Circ. 28107
Loading...
 
 ), "Source
1", is fading with 3-sigma significance, and is therefore likely the
GRB afterglow. Using 4152 s of PC mode data and 4 UVOT images, we find
an enhanced XRT position (using the XRT-UVOT alignment and matching
UVOT field sources to the USNO-B1 catalogue): RA, Dec = 196.82291,
-51.63937 which is equivalent to:

RA (J2000): 13h 07m 17.50s
Dec(J2000): -51d 38' 21.7"

with an uncertainty of 2.2 arcsec (radius, 90% confidence). This
position is 95 arcsec from the Swift/BAT position.  The source is
fading with alpha >0.5.

A spectrum formed from the PC mode data can be fitted with an absorbed
power-law with a photon spectral index of 1.6 (+0.6, -0.3). The
best-fitting absorption column is  consistent with the Galactic value
of 3.1 x 10^21 cm^-2 (Willingale et al. 2013). The counts to observed
(unabsorbed) 0.3-10 keV flux conversion factor deduced from this
spectrum  is 4.6 x 10^-11 (5.6 x 10^-11) erg cm^-2 count^-1. 

A summary of the PC-mode spectrum is thus:
Total column:	     3.1 (+/-2.2) x 10^21 cm^-2
Galactic foreground: 3.1 x 10^21 cm^-2
Excess significance: <1.6 sigma
Photon index:	     1.6 (+0.6, -0.3)
