TITLE: GCN CIRCULAR NUMBER: 37011 SUBJECT: GRB 240801B: AstroSat CZTI Updated classification - likely a solar flare DATE: 24/08/02 03:09:48 GMT FROM: Gaurav Waratkar at IIT Bombay gauravwaratkar@iitb.ac.in
G. Parwani (IITB), U. Pathak (IITB), D. Saraogi (IITB), G. Waratkar (IITB), and V. Bhalerao (IITB) report on behalf of the AstroSat CZTI collaboration:
We undertook a detailed analysis of GRB 240801B (Dasgupta et al., GCN Circ. 36996) with the AstroSat/CZTI localization framework (Saraogi et al., 2024, MNRAS, 530, 2; doi:10.1093/mnras/stae435). Our recovered sky localization from this framework is consistent with the location of the Sun. We thus classify this trigger as a likely solar flare, consistent with the classification by Fermi/GBM (S. Bala, GCN Circ. 37006).
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.
