The YSOVAR (Young Stellar Object VARiability) Spitzer Space Telescope observing program obtained the
first extensive mid-infrared (IRAC 3.6 and 4.5 micron) time series photometry of the Orion Nebula Cluster
plus smaller fields in 11 other star-forming cores (AFGL 490, NGC 1333, Mon R2, GGD 12-15, NGC 2264,
L1688, Serpens Main, Serpens South, IRAS 20050+2720, IC 1396A, and Ceph C).
There are ~29,000 unique objects with light curves in either or both IRAC channels in the YSOVAR
data set. YSOVAR is a sister project to the Coordinated Synoptic Investigation of NGC 2264 (CSI 2264

the details of target selection, data reduction, and other conventions established for this project.
The first delivery (October 2015) from YSOVAR includes data from the four clusters that have been published:
Please see the delivery documentation for more information about what, exactly, is included in this delivery for these four clusters.
