We have a unique opportunity to catch an FUor outburst, HBC 722, in the act. We request ToO time to observe this source from 50-670 um at the earliest opportunity, and a re-observation on the virgul 0.5 yr timeframe to observe variability.

Herschel was launched on 14 May 2009! It is the fourth cornerstone mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched. It is performing photometry and spectroscopy in approximately the 55-671 µm range, bridging the gap between earlier infrared space missions and groundbased facilities.
