SUPERNOVAE 2005hh AND 2005hi

on images taken with the Palomar Oschin 1.2-m telescope (+ QUEST
II camera) as part of the NEAT component of the Palomar-QUEST survey
(cf. CBET 263).  Spectra (range 320-1000 nm) obtained with the
University of Hawaii 2.2-m telescope (+ Supernova Integral Field
Spectrograph) show both objects to be type-Ia supernovae.
     SN 2005hh, found at magnitude approximately 19.3 (calibrated to
R) in an image obtained on Oct. 20.5 UT, is located at R.A. =
4h13m05s.51, Decl. = -25o04'00".5 (equinox 2000.0).  A spectrogram
obtained on Oct. 24.5 shows 2005hh to be at an approximate redshift
of z = 0.065 and about three to four weeks past maximum light.
     SN 2005hi, found at mag approximately 18.9 on Oct. 23.3, is
located at R.A. = 2h41m00s.24, Decl. = +16o42'38".2.  A spectrogram
from Oct. 24.4 shows 2005hi at redshift z approximately 0.075 and
approximately one week after maximum.
