GCN Circular #28098
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.
The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2020/bn200714774/quicklook/glg_skymap_all_bn200714774.png

GCN Circular #28099
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.

GCN Circular #28103
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) 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) and the BALROG localization (GCN 28099).
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.

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 https://www.swift.ac.uk/ToO_GRBs/00021017.
Further observations are planned.

GCN Circular #28108
C. Fletcher (USRA), R. Dunwoody (UCD), J. Mangan (UCD) and C. Meegan (UAH) report on behalf of the Fermi GBM Team:
"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). The Fermi GBM Final Real-time Localization (GCN 28098) 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: https://heasarc.gsfc.nasa.gov/W3Browse/fermi/fermigbrst.html

V. D'Elia (ASDC), A. D'Ai (INAF-IASFPA), B. Sbarufatti (PSU), D.N. Burrows (PSU), J. D. Gropp (PSU), A.P. Beardmore (U. Leicester), J.P. Osborne (U. Leicester), A. Melandri (INAF-OAB) and P.A. Evans (U. Leicester) report on behalf of the Swift-XRT team:
Swift-XRT has conducted further observations of the field of the Swift/BAT-GUANO-detected burst GRB 200714E (Tohuvavohu et al. GCN Circ. 28103). 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), "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)
```
