K. Yamaoka (Nagoya U.) report on behalf of the MAXI team:

The MAXI/GSC nova-alert system triggered on a bright short burst at 15:16:35 UT on 2016 Jun 20.
The position is consistent with that of SGR 1935+2154 (see also Stanbro et al. GCN 19544).
Although the current sky coverage of this burst is by the gas-leaking camera, 
we have tentatively estimated the 2-20 keV flux to be ~80 counts/s (>20 crab).
