A final epoch of YSO variability in Orion

In the past few years, the importance of episodic accretion in young stellar objects has become clear, with up to 40% of the stellar mass accreted during outbursts. We propose final observations of 36 protostars and pre-ms stars in Orion that have shown > 1 magnitude variability. This will provide the final observations at these wavelengths for the foreseeable future, and will extend the data for these YSOs from 2004 to 2020.
