The intermediate Palomar Transient Factory

In February this year the iPTF (intermediate Palomar Transient Factory) program was started.
This is a survey searching for optical transients using a robotic 1.2 meter telescope in California, and the Oskar Klein Centre is one of the participating institutes for the next 2 years. The aim is to discover transients – in particular supernovae – at an earlier stage than hitherto possible, hopefully within hours after the explosion. The concrete scientific question we want to address is the nature of the progenitor systems of supernovae, and this requires very early observations of these explosions, before the memory of the initial configuration gets lost.
