P. Minaev (IKI), A. Pozanenko (IKI) report:

We analyzed the publicly available SPI-ACS data (>~ 80 keV) of INTEGRAL 
observatory covering trigger time (UT) 20:57:02 of the GRB 190114C 
(Gropp et al. 2019, GCN 23688; Hamburg et al. 2019, GCN 23707).

We found statistically significant extended emission up to ~ 5000 sec 
after the trigger. The extended emission can be approximated by power 
law model with the index of 0.99 +/- 0.05.

We do not detect any significant emission from possible precursor on 
time scales 0.05 ��� 10 sec within (-500, 0) sec time interval before the 

The SPI-ACS/INTEGRAL light curve can be found at:
