report on behalf of the AGILE Team:

The AGILE Mini-CALorimeter (MCAL) detected a short burst at
T0 = 2020-12-27 15:14:07.40 +/- 0.01 s (UTC) detected also by
Fermi/GBM (trigger 630774852).

The event lasted about 0.10 s and released a total number of ~480 counts
in the detector (in the 0.4-100 MeV energy range),
above an average background rate of 676 counts / s.

The light curve shows a single sharp peak and can be found at
http://www.agilescienceapp.it/notices/GRB_071058_536166847.405605.png.

The AGILE-MCAL detector is a CsI detector with a 4 pi FoV,
sensitive in the energy range 0.4-100 MeV.

Additional analysis of AGILE data is in progress.
