SUPERNOVAE 2005dd, 2005de, AND 2005df

Further to IAUC 8570, E. Lee, N. J. Ponticello, and R. J.
Foley report the LOSS/KAIT discovery of two apparent supernovae on
unfiltered KAIT images, as tabulated below.  SN 2005de was
independently discovered by T. Puckett and J. Tigner at mag 18.0 on
an unfiltered CCD frame taken with the 0.60-m patrol telescope (cf.
IAUC 8569) on Aug. 3.13 UT.
