SUPERNOVAE 2006ua-2006ue
     D. Sand, Steward Observatory, in collaboration with D. Zaritsky,
S. Herbert-Fort, S. Sivanandram, and D. Clowe, reports the discovery
of five type-Ia supernovae on g-band images obtained at the Steward
Observatory 2.3-m Bok telescope (+ 90Prime imager) on 2006 Dec. 16 UT.
In each case, no transient was detected in a "90Prime" imaging run
during 2006 Nov. 15-18 (or many previous "90Prime" imaging epochs) down
to a limiting point-source magnitude of g about 23.  Follow-up
spectroscopy was done with the Blue Channel Spectrograph at the MMT
during Dec. 20.15-20.50.  T. Matheson confirmed the identifications of
each object as a type-Ia event.
