The Fermi GBM team reports the detection of a likely LONG GRB
At 12:24:32 UT on 14 May 2022, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 220514A (trigger 674223877.638218 / 220514517).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 145.6, Dec = 13.6 (J2000 degrees, equivalent to J2000 09h 42m, 13d 35'), with a statistical uncertainty of 1.8 degrees.
The angle from the Fermi LAT boresight is 102.0 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 674223877 at 12:24:32 on 14 May 2022 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) = 145.7+/-0.8 deg
Decl.(2000.0) = 11.6+/-1.6 deg
```
We estimate an additional systematic error of 2 deg.

a gamma-ray burst lasting about 70 s has been detected by IBAS in the IBIS/ISGRI data at 12:24:25 UT of 2022 May 14.
The refined coordinates (J2000) are:
```
R.A. =   147.6670 deg
DEC. =   +13.1472 deg
```
with an uncertainty of 1.5 arcmin (90% c.l.).
Due to telemetry saturation, we can estimate only a lower limit of about 4e-6 erg/cm2 on the 20-200 keV fluence. The burst was detected also by the Fermi/GBM instrument (GCN Circ. 32038).

S. de Wet (UCT), P.M. Vreeswijk (Radboud) and D.B. Malesani (Radboud and DAWN/NBI) report on behalf of the MeerLICHT consortium:
Following the detection of GRB 220514A by Fermi/GBM (Fermi GBM Team, GCN 32038) and INTEGRAL (Mereghetti et al., GCN 32041), the 0.6m wide-field MeerLICHT telescope, located at Sutherland, South Africa obtained two 300 s exposures of a field containing the INTEGRAL position in the q-band beginning 6.75 hours after the GRB trigger. Based on an existing MeerLICHT reference image of this field, we detect a new transient candidate within the INTEGRAL error box with AB magnitude q = 19.89 +\- 0.13 at coordinates:
```
RA (J2000) = 09:50:39.73 (147.66556d)
Dec (J2000) = 13:09:22.61 (+13.15628d)
```
calibrated against Gaia DR2. This position is 33" from the centre of the INTEGRAL error box, and no source is visible at the transient position in Pan-STARRS images of the field. We suggest this may be the optical afterglow to GRB 220514A. Further follow-up is encouraged.
MeerLICHT is built and run by a consortium consisting of Radboud University, University of Cape Town, the South African Astronomical Observatory, the University of Oxford, the University of Manchester and the University of Amsterdam.

Observations were performed in the clear (roughly R) filter, and the exposure time was 60s per image, with a total of 64 images were obtained. We marginally detected the optical afterglow reported by de Wet et al.

"At 12:24:32.64 UT on 14 May 2022, the Fermi Gamma-Ray Burst Monitor (GBM) triggered and located GRB 220514A (trigger 674223877 / 220514517), which was also detected by INTEGRAL (Mereghetti et al. 2022, GCN 32041).
The Fermi GBM Final Real-time Localization has been reported in GCN 32038.
The angle from the Fermi LAT boresight at the GBM trigger time is 102 degrees.
The GBM light curve shows multiple peaks with a duration (T90) of about 66 s (50-300 keV). The time-averaged spectrum from T0-2.8 s to T0+64.8 s is best fit by a Band function with Epeak = 139 +/- 21 keV, alpha = -1.25 +/- 0.06, and beta = -1.92 +/- 0.06.
The event fluence (10-1000 keV) in this time interval is (3.0 +/- 0.1)E-05 erg/cm^2. The 1-sec peak photon flux measured starting from T0+28.9 s in the 10-1000 keV band is 16.6 +/- 0.5 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

The first observations were obtained with TNT, starting 1.57 h after the Fermi/GBM and INTEGRAL/IBAS trigger time, in which we detect the afterglow.
We furthermore detect the optical afterglow with MOSS 7.95h after trigger at a magnitude of 20.18 +/- 0.15 mag in a Clear image. The afterglow is also detected in a stack by the 2.2m CAHA equipped with the CAFOS instrument 9.58h after trigger in the i' band at 19.86 +/- 0.16 mag. Upper limits are given at 3 sigma.
The following table displays part of our photometry with magnitudes given in the AB system and calibrated with respect to field stars from the Pan-STARRS and APASS catalogs, using the MUPHOTEN pipeline (Duverne et al. 2021). The FRAM image has been calibrated versus GAIA DR2 G magnitudes.

We observed the field of GRB 220514A (Fermi GBM team et al. GCN Circular #32038, Biltzinger et al. GCN Circular #32039, Mereghetti et al. GCN Circular #32041, Lipunov et al. GCN Circular #32042, de Wet et al. GCN Circular #32044, Zheng et al. GCN Circular #32051, Bissaldi et al. GCN Circular #32054, Yan et al. GCN Circular #32058) with the optical three color (g', Rc, and Ic) CCD cameras attached to the MITSuME 50 cm telescope Akeno.
The observation with a series of 60 sec exposures started at 2022-05-14 12:25:15 UT(47 seconds after the Fermi/GBM trigger). We stacked the images with good conditions. Here we report magnitudes by the forced-photometry at the position of the optical afterglow (GCN Circulars # 32044, #32051, #32058) and 5-sigma limits.

Analysis of AstroSat CZTI data with the CIFT framework (Sharma et al., 2021, JApA, 42, 73) showed detection of a long GRB 220514A, which was also reported by Fermi GBM ( GCN 32028), INTEGRAL (Mereghetti et al., GCN 32041) and BALROG ( Biltzinger et al. GCN 32029).
The source was clearly detected in the 20-200 keV energy range. The light curve showed multiple peaks of emission with the strongest peak at 2022-05-14 at 12:24:58.50 UT. The measured peak count rate associated with the burst is 346 (+51, -30) counts/s above the background in the combined data of four quadrants, with a total of 4001 (+588, -793) counts. The local mean background count rate was 561 (+2, -3) counts/s. Using cumulative rates, we measure a T90 of 54 (+9, -5) s.
It was also clearly detected in the CsI anticoincidence (Veto) detector in the 100-500 keV energy range. The light curve peaks at 2022-05-14 at 12:24:57.99 UT. The measured peak count rate is 401 (+75, -80) counts/s above the background in the combined Veto data of four quadrants, with a total of 2095 (+596, -592) counts. The local mean background count rate was 1935 (+3, -4) counts/s. We measure a T90 of 29 (+4, -8) s from the cumulative Veto light curve.
This is the 500th GRB detected by AstroSat CZTI since its launch in September 2015, with an average rate of 75 GRBs/year.
CZTI GRB detections are reported regularly on the payload site at http://astrosat.iucaa.in/czti/?q=grb. CZTI is built by a TIFR-led consortium of institutes across India, including VSSC, ISAC, IUCAA, SAC, and PRL. The Indian Space Research Organisation funded, managed, and facilitated the project.
GCN Circular #32095
Aaron Tohuvavohu (U Toronto), Gayathri Raman (PSU), James DeLaunay (UAlabama), Jamie A. Kennea (PSU), report:
Swift/BAT did not localize GRB 220514A onboard (T0: 2022-05-14T12:24:32 UTC, Fermi/GBM GCN 32038, INTEGRAL GCN 32041, AstroSat GCN 32070, GECAM detection).
The Fermi, INTEGRAL, and GECAM notices, distributed in near real-time, triggered the Swift Mission Operations Center operated Gamma-ray Urgent Archiver for Novel Opportunities (GUANO; Tohuvavohu et al. 2020, ApJ, 900, 1).
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.
The BAT likelihood search, NITRATES (DeLaunay + Tohuvavohu, arXiv:2111.01769), detects the burst with a sqrt(TS) of 24.9 in a 16.384 s analysis time bin. The burst episode as seen by BAT is >50 s long.
NITRATES results indicate a burst coming from outside the coded FoV, with DeltaLLHOut of -29.7. The most likely sky position from NITRATES agrees well with the INTEGRAL/IBAS position (GCN 32041).
See Section 9.1 and Figure 20 in the NITRATES paper for brief descriptions and interpretation of sqrt(TS), DeltaLLHPeak, and DeltaLLHOut.
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/
