The BHTOM.space network coordinated an extensive campaign to monitor SN2024iss, Type IIb nearby supernova, reported as GOTO24bmf, ZTF24aankvcy and Gaia24bot in a dwarf galaxy in the Coma cluster of galaxies. Observations commenced on May 16th, shortly after the supernova’s discovery, and continued through December 27th, 2024. During this period, 241 measurements were obtained using multiple telescopes globally. Photometric data were taken in various filters and subsequently transformed into Gaia Synthetic Photometry (GaiaSP) for consistency.
Our data show that SN2024iss reached its peak brightness around May 31st, 2024. Since then, the light curves indicate a consistent decline in brightness across all observed bands. Interestingly, a pre-peak brightening was detected in all bands, which aligns with similar features observed in ZTF and ATLAS data.
Detailed light curves and associated statistics are presented on the webpage: https://www.astrouw.edu.pl/~wyrzykow/BHTOM/SN2024iss/. Further details and the full photometric dataset are available for download by registered users of the BHTOM.space platform.
