Nearby Supernova Factory

The Nearby Supernova Factory was an astronomical survey aimed at finding supernovae, which collected data from 2003 to 2008. The survey used data from the NEAT (Near-Earth Asteroid Tracking) survey, feeding that data in real time into software to identify possible supernovae. The survey then followed up with spectroscopic observations using the UH88 telescope at Mauna Kea Observatories.

As far as I can tell, Nearby Supernova Factory II was a subsequent effort to apply the same follow-up observations and analysis to later supernovae discovered by other surveys, e.g., the Palomar Transient Factory (PTF). Much of the analysis-effort by these projects was to refine the use of Type Ia supernovae as standard candles.
