Supernova SN 2024xyz

SN 2024xyz

Type II-P

A Type II-P supernova in the barred spiral galaxy NGC 2903 in Leo, exhibiting a classic plateau phase.

SN 2024xyz was first flagged by the ATLAS survey and confirmed spectroscopically as a Type II-P supernova showing prominent hydrogen Balmer lines. Anysllum began photometric follow-up within 48 hours of the announcement, capturing the early plateau phase in V and R bands over a seven-week baseline. The plateau magnitude held steady near 13.6 for approximately 80 days before the expected drop onto the radioactive tail, providing a textbook demonstration of core-collapse supernova behavior in a galaxy just 30 million light-years away.
