About CSI 2264

CSI 2264 is an Exploration Science program being conducted by the Spitzer Space Telescope during its warm mission with the InfraRed Array Camera (IRAC).

The Coordinated Synoptic Investigation of NGC 2264 (CSI 2264) photometrically monitored the star-forming region NGC 2264 for 30+ days starting in December 2011. It constitutes a unique cooperative effort including 15 ground- and space- based telescopes. It was conceived of in the process of executing the Young Stellar Object Variability (YSOVAR) project (Morales-Calderon et al. 2011; Rebull et al. 2014, AJ, in press), and involves many of the same people and processing approach. These projects are exploring the variability properties of young stars in several young clusters at an unprecedented combination of cadence, photometric precision, and wavelength coverage, particularly in the infrared.

The CSI 2264 project performed photometric monitoring of young NGC 2264 cluster members using the Spitzer Infrared Array Camera (IRAC; Fazio et al. 2004) and the Convection, Rotation and Planetary Transits satellite (CoRoT; Baglin et al. 2006) simultaneously. Thirteen other telescopes monitored the region at different times concurrently with (or closely in time to) the primary Spitzer and CoRoT joint campaign.

The CSI 2264 project is described in detail in Cody et al. (2014).
