GCN Circular #33420
The Fermi GBM team reports the detection of a likely SHORT GRB
At 13:32:27 UT on 8 Mar 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230308A (trigger 699975152.401482 / 230308564).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 94.9, Dec = 68.5 (J2000 degrees, equivalent to J2000 06h 19m, 68d 30'), with a statistical uncertainty of 1.2 degrees.
The angle from the Fermi LAT boresight is 42.0 degrees.

GCN Circular #33421
F. Kunzweiler, B. Biltzinger, F. Berlato, J. Burgess & J. Greiner (all MPE Garching) report:
The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger 699975152 at 13:32:27 on 08 March 2023 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) = 104.5+/-7.6 deg
Decl.(2000.0) = 67.3+/-1.3 deg
```
We estimate an additional systematic error of 2 deg.

Tempesta (TeleSpazio), report on behalf of the AGILE Team:
The AGILE satellite detected the short GRB 2300308A at T0 = 2023-03-08 13:32:27.400 (UTC), reported by Fermi/GBM (GCN #33420) and BALROG (GCN #33421).
The burst is clearly visible in the AGILE scientific ratemeters of the MiniCALorimeter (MCAL; 0.4-100 MeV), and in all the panels of the AntiCoincidence detectors (AC Top, 50-200 keV, ACLat, 80-200 keV). The event lasted about 1 s and it released a total number of 1166 counts in the MCAL detector (above a background rate of 576 Hz), and 7526 counts in the AC Top detector (above a background rate of 3445 Hz). The AGILE ratemeters light curves can be found at: http://www.agilescienceapp.it/notices/GRB230308A_AGILE_RM_ND.png .
The event also triggered a high-time resolution MCAL data acquisition, from T0 to T0+12 s (UTC), and released 1484 counts in the detector, above a background rate of 590 Hz. The MCAL light curve can be found at: http://www.agilescienceapp.it/notices/GRB230308A_082579_605367147.400000.png .
At the T0 the event was 133 deg off-axis. Additional analysis of AGILE data is in progress. Automatic MCAL GRB alert Notices can be found at: https://gcn.gsfc.nasa.gov/agile_mcal.html
GCN Circular #33440
C. Malacaria (ISSI) reports on behalf of the Fermi GBM Team:
"At 13:32:27.40 UT on 8 March 2023, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 230308A (trigger 699975152 / 230308564). The Fermi GBM Final Real-time Localization was reported in GCN 33420.
The angle from the Fermi LAT boresight at the GBM trigger time is 42 degrees.
The GBM light curve consists of a slightly structured main peak with a duration (T90) of about 0.6 s (50-300 keV). The time-averaged spectrum from T0-0.064 s to T0+0.64 s is best fit by a power law function with an exponential high-energy cutoff. The power law index is -0.52 +/- 0.03 and the cutoff energy, parameterized as Epeak, is 943 +/- 46 keV.
A Band function fits the spectrum equally well with Epeak= 907 +/- 52 keV, alpha = -0.51 +/- 0.03, beta = -3.1 +/- 0.4 .
The event fluence (10-1000 keV) in this time interval is (8.5 +/- 0.2)E-06 erg/cm^2. The 0.064-sec peak photon flux measured starting from T0 in the 10-1000 keV band is 72 +/- 2 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 short GRB 230308A (Fermi GBM Final Real-time Localization: Fermi GBM team, GCN Circ. 33420; BALROG localization: Kunzweiler et al., GCN Circ 33421; AGILE/MCAL detection: Casentini et al., GCN Circ 33435; Fermi GBM detection: Malacaria et al., GCN Circ 33440) triggered the CALET Gamma-ray Burst Monitor (CGBM) at 13:32:27.34 UTC on 8 March 2023 (http://cgbm.calet.jp/cgbm_trigger/flight/1362317395/index.html). The burst signal was seen by all CGBM detectors.
The burst light curve shows a multi-peaked structure that starts at T+0.04 sec, peaks at T+0.21 sec, and ends at T+0.37 sec. The T90 and T50 durations measured by the SGM data are 0.29 +/- 0.04 sec and 0.17 +/- 0.04 sec (40-1000 keV), respectively.

The bright, short-duration GRB 230308A (Fermi-GBM detection: the Fermi GBM team, GCN Circ. 33420; Malacaria et al., GCN Circ. 33440; BALROG localization: Kunzweiler et al., GCN Circ. 33421; AGILE-MCAL detection: Casentini et al., GCN Circ. 33435) was detected by Fermi(GBM trigger 699975152), Konus-Wind, INTEGRAL (SPI-ACS), AGILE (MCAL), Mars-Odyssey (HEND), and BepiColombo (MGNS) at about 48747 s UT (13:32:27).
We have triangulated it to a preliminary, 3 sigma error box whose coordinates are:
```
  ---------------------------------------------
   RA(2000), deg                 Dec(2000), deg
  ---------------------------------------------
  Center:
    96.381 (06h 25m 31s) +66.621 (+66d 37' 17")
  Corners:

    96.417 (06h 25m 40s) +66.562 (+66d 33' 42")

```
The error box area is 35 sq. arcmin, and its maximum dimension is 9 arcmin (the minimum one is 6.1 arcmin). The Sun distance was 101 deg.
This box may be improved.
The IPN localization is consistent with, but reduces the area of, the Fermi-GBM final localization (GCN 33420) and the BALROG localization (GCN 33421).

The Konus-Wind time history and spectrum will be given in a forthcoming GCN Circular.
GCN Circular #33510
D. Svinkin, D. Frederiks, M. Ulanov, A. Tsvetkova, A. Lysenko, A. Ridnaia, and T. Cline on behalf of the Konus-Wind team, report:
The short-duration GRB 230308A (Fermi-GBM detection: the Fermi GBM team, GCN Circ. 33420; Malacaria et al., GCN Circ. 33440; BALROG localization: Kunzweiler et al., GCN Circ. 33421; AGILE-MCAL detection: Casentini et al., GCN Circ. 33435; CALET-GBM detection: Shimizu et al., GCN Circ. 33452; IPN triangulation: Kozyrev et al., GCN Circ. 33477) triggered Konus-Wind at T0=48749.809 s UT (13:32:29.809).
The burst light curve shows a multi-peaked structure which starts at ~T0 and has a total duration of ~0.6 s. The emission is seen up to ~4 MeV.
The Konus-Wind light curve of this GRB is available at http://www.ioffe.ru/LEA/GRBs/GRB230308_T48749/
As observed by Konus-Wind, the burst had a fluence of 1.31(-0.14,+0.16)x10^-5 erg/cm2, and a 16-ms peak flux, measured from T0-2 ms, of 8.03(-1.52,+1.61)x10^-5 erg/cm2/s (both in the 20 keV - 10 MeV energy range).
The time-averaged spectrum of the burst (measured from T0 to T0+0.256 s) is best fit in the 20 keV - 4 MeV range by the GRB (Band) model with the following parameters: the low-energy photon index alpha = -0.29(-0.14,+0.17), the high energy photon index beta = -3.22(-6.78,+0.76), the peak energy Ep = 936(-162,+161) keV (chi2 = 47/45 dof).
All the quoted errors are at the 90% confidence level. All the quoted values are preliminary.
