Kunegunda Belle, Don Hoard and Steve Howell are observing two cataclysmic variables with Spitzer during the next couple of weeks. They request ground-based light curves spanning the observation intervals so that they can identify the state each variable is in during the Spitzer visits.
1. EX HYA (12:52:24.20, -29:14:56.0, AUID 000-BBT-323)
