The Sloan Digital Sky Survey-II (SDSS-II) has embarked on a multi-year project to
identify and measure light curves for intermediate-redshift (0.05 < z < 0.35) Type Ia supernovae
(SNe Ia) using repeated five-band (ugriz) imaging over an area of 300 sq. deg.
The survey region is a stripe 2.5◦ wide centered on the celestial equator in the Southern
Galactic Cap that has been imaged numerous times in earlier years, enabling construction
of a deep reference image for discovery of new objects. Supernova imaging observations
are being acquired between 1 September and 30 November of 2005-7. During
the first two seasons, each region was imaged on average every five nights. Spectroscopic
follow-up observations to determine supernova type and redshift are carried out
on a large number of telescopes. In its first two three-month seasons, the survey has
discovered and measured light curves for 327 spectroscopically confirmed SNe Ia, 30
probable SNe Ia, 14 confirmed SNe Ib/c, 32 confirmed SNe II, plus a large number of
photometrically identified SNe Ia, 94 of which have host-galaxy spectra taken so far.
This paper provides an overview of the project and briefly describes the observations completed during the first two seasons of operation.
