Giuliani (INAF/IASF-Mi),\nand P. Tempesta (TeleSpazio), report on behalf of the AGILE Team:\n\nThe AGILE Mini-CALorimeter (MCAL) detected the GRB 230102A at T0 =\n2023-01-02 00:22:12.97 +/- 0.01 s (UTC), reported by Fermi GBM (GCN #33137).\n\nThe event lasted about 0.16 s and released a total number of 219 counts in\nthe MCAL detector (in the 0.4-100 MeV energy range), above an average\nbackground rate of 489 Hz. The MCAL light curve can be found at\nhttp://www.agilescienceapp.it/notices/GRB230102A_081632_599703732.970000.png\n. The time-integrated spectrum of the burst, from T0-0.032 s to T0+0.128 s,\ncan be fitted in the energy range 0.4-2 MeV with a power-law with ph.ind. =\n-2.48 (-0.46,+0.51), resulting in a reduced chi-squared of 0.85 (21 d.o.f.)\nand a fluence of 1.07e-06 erg/cm^2 (90% confidence level), in the same\nenergy range. At the T0, the event was 100 deg off-axis.\n\nThe AGILE-MCAL detector is a CsI detector with a 4 pi FoV, sensitive in the\nenergy range 0.4-100 MeV. Additional analysis of AGILE data is in progress.\nAutomatic MCAL GRB alert Notices can be found at:\nhttps://gcn.gsfc.nasa.gov/agile_mcal.html.",
