GCN Circular #32392
The Fermi GBM team reports the detection of a likely LONG GRB
At 13:58:06 UT on 14 Jul 2022, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 220714B (trigger 679499891.272708 / 220714582).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 45.9, Dec = -22.6 (J2000 degrees, equivalent to J2000 03h 03m, -22d 36'), with a statistical uncertainty of 2.8 degrees.
The angle from the Fermi LAT boresight is 124.0 degrees.

Williams (PSU) report on behalf of the Neil Gehrels Swift Observatory Team:
At 13:58:04 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 220714B (trigger=1116221). Swift slewed immediately to the burst. The BAT on-board calculated location is RA, Dec 47.072, -19.334 which is
```
   RA(J2000) = 03h 08m 17s
   Dec(J2000) = -19d 20' 02"
```
with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a complex structure with a duration of about 40 sec. The peak count rate was ~5500 counts/sec (15-350 keV), at ~13 sec after the trigger.
The XRT began observing the field at 13:59:20.9 UT, 76.4 seconds after the BAT trigger. XRT found a bright, uncatalogued X-ray source located at RA, Dec 47.0803, -19.3269 which is equivalent to:
```
   RA(J2000)  = 03h 08m 19.27s
   Dec(J2000) = -19d 19' 36.8"
```
with an uncertainty of 5.2 arcseconds (radius, 90% containment). This location is 38 arcseconds from the BAT onboard position, within the BAT error circle. No event data are yet available to determine the column density using X-ray spectroscopy.
The initial flux in the 2.5 s image was 1.70e-09 erg cm^-2 s^-1 (0.2-10 keV).
UVOT took a finding chart exposure of 56 seconds with the White filter starting 121 seconds after the BAT trigger. No credible afterglow candidate has been found in the initial data products. The 2.7'x2.7' sub-image covers none of the XRT position. Data from the list of sources generated on-board are not available at this time. No correction has been made for the expected extinction corresponding to E(B-V) of 0.032.
Burst Advocate for this burst is S. Laha (sib.laha AT gmail.com). Please contact the BA by email if you require additional information regarding Swift followup of this burst. In extremely urgent cases, after trying the Burst Advocate, you can contact the Swift PI by phone (see Swift TOO web site for information: http://www.swift.psu.edu/)

P.A. Evans, M.R. Goad, J.P. Osborne and A.P. Beardmore (U. Leicester) report on behalf of the Swift-XRT team.
Using 1471 s of XRT Photon Counting mode data and 4 UVOT images for GRB 220714B, we find an astrometrically corrected X-ray position (using the XRT-UVOT alignment and matching UVOT field sources to the USNO-B1 catalogue): RA, Dec = 47.08386, -19.32962 which is equivalent to:

RA (J2000): 03h 08m 20.13s
Dec (J2000): -19d 19' 46.6"
```
with an uncertainty of 2.1 arcsec (radius, 90% confidence).
This position may be improved as more data are received. The latest position can be viewed at http://www.swift.ac.uk/xrt_positions. Position enhancement is described by Goad et al. (2007, A&A, 476, 1401) and Evans et al. (2009, MNRAS, 397, 1177).

F.E. Marshall (NASA/GSFC) and S. Laha (GSFC/UMBC) report on behalf of the Swift team:
UVOT took a finding chart exposure of 150 seconds with the White filter starting 3552 seconds after the BAT trigger. There is a candidate afterglow in the rapidly available 2.7'x2.7' sub-image at
```
  RA(J2000)  =     03:08:20.18 =  47.08409
  DEC(J2000) = -19:19:45.3  = -19.32925

with a 90%-confidence error radius of about 0.61 arc sec. This position is 1.5 arc sec. from the center of the XRT error circle (Evans et al. GCN Circ. 32395). The estimated magnitude is 16.52 with a 1-sigma error of about 0.14. No correction has been made for the expected extinction corresponding to E(B-V) of 0.032.

We have analysed 6.0 ks of XRT data for GRB 220714B (Laha et al. GCN Circ. 32393), from 71 s to 45.6 ks after the BAT trigger. The data comprise 135 s in Windowed Timing (WT) mode (the first 4 s were taken while Swift was slewing) with the remainder in Photon Counting (PC) mode. The enhanced XRT position for this burst was given by Evans et al. (GCN Circ. 32395).
The late-time light curve (from T0+3.5 ks) can be modelled with a power-law decay with a decay index of alpha=1.22 (+/-0.04).
A spectrum formed from the WT mode data can be fitted with an absorbed power-law with a photon spectral index of 3.95 (+0.19, -0.18). The best-fitting absorption column is 2.7 (+/-0.3) x 10^21 cm^-2, in excess of the Galactic value of 3.2 x 10^20 cm^-2 (Willingale et al. 2013). The PC mode spectrum has a photon index of 2.03 (+/-0.10) and a best-fitting absorption column of 1.47 (+0.28, -0.27) x 10^21 cm^-2. The counts to observed (unabsorbed) 0.3-10 keV flux conversion factor deduced from this spectrum is 3.4 x 10^-11 (4.4 x 10^-11) erg cm^-2 count^-1.
A summary of the PC-mode spectrum is thus:
```
Total column:	     1.47 (+0.28, -0.27) x 10^21 cm^-2
Galactic foreground: 3.2 x 10^20 cm^-2
Excess significance: 7.0 sigma
Photon index:	     2.03 (+/-0.10)
```
If the light curve continues to decay with a power-law decay index of 1.22, the count rate at T+24 hours will be 0.059 count s^-1, corresponding to an observed (unabsorbed) 0.3-10 keV flux of 2.0 x 10^-12 (2.6 x 10^-12) erg cm^-2 s^-1.

R. Strausbaugh (U. of the Virgin Islands), A. Cucchiara (College of Marin) report on behalf of a larger collaboration:
We observed the Swift GRB 220714B (Laha et al., GCN 32393) field with the LCO 1-meter Sinistro instrument at the South African Astronomical Observatory site, on July 15, from 02:32 to 02:59 UT (corresponding to 13.57 to 14.02 hours from the GRB trigger time) with the SDSS r and i filters.
We performed a series of 3x300s exposures in i and r bands. We detect an optical counterpart at the same position as the UVOT afterglow (Marshall et al., GCN 32396) in both bands.
The following magnitudes are calculated using the PanSTARRS catalog as reference:
```
r = 19.77 +/- 0.07
i = 19.44 +/- 0.07
```
These magnitudes are not corrected for galactic extinction.

S. Dalessi (UAH), C. Fletcher (USRA) and C. Meegan (UAH) report on behalf of the Fermi GBM Team:
"At 13:58:06.27 UT on 14 July 2022, the Fermi Gamma-Ray Burst Monitor (GBM) triggered and located GRB 220714B (trigger 679499891 / 220714582) which was also detected by the Swift/BAT (S. Laha et al. 2022, GCN 32393) The Fermi GBM Final Real-time Localization (GCN 32392) is consistent with the Swift position.
The angle from the Fermi LAT boresight at the GBM trigger time is 121 degrees.
The GBM light curve consists of multiple peaks with a duration (T90) of about 28 s (50-300 keV). The time-averaged spectrum from T0-3.07 s to T0+26.6 s is well by a power law function with an exponential high-energy cutoff. The power law index is -1.63 +/- 0.06 and the cutoff energy, parameterized as Epeak, is 139 +/- 24 keV
The event fluence (10-1000 keV) in this time interval is (8.0 +/- 0.4)E-06 erg/cm^2. The 1-sec peak photon flux measured starting from T0+11.0 s in the 10-1000 keV band is 6.5 +/- 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

Using the data set from T-173 to T+963 sec from the recent telemetry downlink, we report further analysis of BAT GRB 220714B (trigger #1116221) (Laha, et al., GCN Circ. 32393). The BAT ground-calculated position is RA, Dec = 47.086, -19.321 deg which is
```
   RA(J2000)  =  03h 08m 20.7s
   Dec(J2000) = -19d 19' 13.8"
```
with an uncertainty of 1.3 arcmin, (radius, sys+stat, 90% containment). The partial coding was 88%.
The mask-weighted light curve shows a complex structure. The main period of emission starts around T-5 sec and continues to T+35 seconds with three main overlapping pulses. There is some precursor activity starting as early as T-45 seconds and low-level emission extending to T+60 seconds. The spacecraft slewed away from the burst location at around T+275 seconds. T90 (15-350 keV) is 50.10 +- 7.96 sec (estimated error including systematics).
The time-averaged spectrum from -48.27 to +45.75 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.92 +- 0.07. The fluence in the 15-150 keV band is 4.4 +- 0.1 x 10^-6 erg/cm2. The 1-sec peak photon flux measured from T+12.89 sec in the 15-150 keV band is 3.8 +- 0.2 ph/cm2/sec. All the quoted errors are at the 90% confidence level.

GCN Circular #32413
N. P. M. Kuin (UCL-MSSL) and S. Laha (NASA/UMCP) report on behalf of the Swift/UVOT team:
The Swift/UVOT began settled observations of the field of GRB 220714B 3628 s after the BAT trigger (Laha et al, GCN Circ. 32393) and detected a bright afterglow (Marshall & Laha, GCN Circ. 32396). Marshal and Laha provided the UVOT position of GRB 220714B. Perhaps due to a bright nearby star in the field, there were some exposures which were cut short, but in this report we include those using the UVOT photometric system (Breeveld et al. 2011, AIP Conf. Proc. 1358, 373):

The magnitudes in the table are not corrected for the Galactic extinction due to the reddening of E(B-V) = 0.032 in the direction of the burst (Schlegel et al. 1998).
