2025 Supernova Boneyard

2025 Supernova Boneyard

Welcome to the Boneyard. On this page you will find entries for objects that have been confirmed as Cataclysmic variables, asteriods (otherwise known as Vermin of the sky), or some other non extragalactic event. Why keep them around? Because you never know when something like this will come back to life...

Flare - Flare star - small Type M stars often flare
galaxy - Spectrum was the sepectrum of a galaxy, not an SN
HII - HII region (gas cloud) in a galaxy
HP - Hot Pixel - Flaw on imager (I also catagorize other imager issues here)
HPM - High Proper Motion (fast moving star)
LPV - Long Period Variable
MP - Minor Planet (asteroid)
Nova - Galactic Nova
NT - Nuclear Transient
QSO - Quasi Stellar Object
Quasar - confirmed QSO
TDE - Tidal Disruption Event (active galaxy)
ulens - Microlens event
unconfirmed - It was discovered, but nobody could confirm the discovery
YSO - Young Steller Object
