Details:
I was able to capture the supernova SN2025ahxd in the galaxy UGC 525 last night between clouds. Using Tycho Tracker, the estimated visual magnitude was 15.21. It has been classified as a Type Ia supernova. That means it’s the thermonuclear explosion of a white dwarf star in a binary system once it accreted enough material to reach the Chandrasekhar limit (~1.4 × the Sun’s mass).
