The Orion A cloud is the most active giant molecular cloud with 500 pc of the Sun. The molecular cloud was surveyed as part of the GTO program with the IRAC and MIPS instruments; these data provided an unbiased census of protostars and young stars in all the environments. This survey found large numbers of relative isolated stars in uncrowded environments parsecs away from the young OB stars in the Orion Nebula. However, recent maps of the molecular cloud show that the Orion A cloud extends further south than previous thought and that only 3/4 of the cloud was mapped in the previous survey. Furthemore, the southern extension of this cloud forms a ring around the B1I star Kappa Ori (or Saiph). We propose to map this region to complete the unbiased survey of the Orion A cloud, to determine if Saiph is indeed interacting with Orion A, and if so, to measure the impact of that interaction on star formation in the Orion A cloud.
