Bhattacharya (Ashoka University/IUCAA), A. R. Rao (IUCAA/TIFR), and S. 
Vadawale (PRL) report on behalf of the AstroSat CZTI collaboration:

Analysis of AstroSat CZTI data with the CIFT framework (Sharma et al., 
2021, JApA, 42, 73) showed the detection of bursts from SGR 1935+2154 as 

Time | Detected_by | GCN
2022-10-12T15:14:04.13 | Fermi-GBM | 32708
2022-10-14T13:20:31.77 | Fermi-GBM | 32764

We also report a forest of seven bright bursts within 15s from 
2022-10-14T17:27:33, that are likely related to SGR 1935+2154.

CZTI is built by a TIFR-led consortium of institutes across India, 
including VSSC, URSC, IUCAA, SAC, and PRL. The Indian Space Research 
Organisation funded, managed, and facilitated the project.
