L. Margot, California Institute of Technology, reports thediscovery on Aug. 14.6 UT of a satellite of (379) Huenna (V = 12.9)from adaptive optics H-band imaging with the 10-m W. M. Keck IItelescope on Mauna Kea.  The satellite was observed to follow theprimary at the non-sidereal rate of roughly 10"/hr for a periodexceeding 2 hr.  On Aug. 14.5518 UT, the companion was at aseparation of 0".89 (projected separation 1200 km) in p.a. 34 deg.The primary-to-secondary H-band flux ratio is about 165, giving adiameter ratio of about 13.SUPERNOVAE 2003he AND 2003hf     Further toIAUC 8179, J.
