   PR #    11
   YY Gem is an eclipsing, double-line spectroscopic binary (P=0.81d)
   whichis very active in X-rays. We will study the spectrum of quiescent
   andpossibly flare X-rays; also, as eclipse in the visual is deep, we
   willsearch for X-ray eclipses (we do not request time critical
   observationssince eclipses last for ~1 ASCA orbit). YY Gem is also a
   component of the Castor system, consisting of a closevisual binary
   Castor A and B as well as YY Gem, A and B being about 70arcsec away
   (15 deg W of N) from YY Gem. A flare and possible quiescentX-rays (but
   could be UV contamination) was detected with EXOSAT; we willattempt to
   deconvolve the image, testing our understanding of the ASCA PSF.
