SUPERNOVAE 2005ma, 2005mb, 2005mc, 2005md, 2005me

Additional supernovae have been discovered on unfiltered CCD
images:  2005ma and 2005mb by T. Puckett (cf. IAUC 8646; with T.
Orff for 2005ma and with T. Ceravolo for 2005mb); 2005mc by the
Tsinghua Center for Astrophysics (THCA) Supernova Survey [F.-Y.
Bian, Y.-Q. Lou, X.-F. Wang, and Y. Yang, THCA, Tsinghua University,
Beijing; and Y.-L. Qiu, National Astronomical Observatories of
China (NAOC)] with the 0.8-m THCA-NAOC Telescope (TNT); 2005md by
W. Li (LOSS/KAIT; cf. IAUC 8646); and 2005me by L. A. G. Monard (cf.
IAUC 8581).

Additional magnitudes for 2005ma in MCG -02-13-13:  Dec. 3, [19.3
(Puckett); 25.20 UT, 17.3 (J. Newton, Portal, AZ, 0.35-m reflector).
Nothing was present at the location of 2005ma on numerous images
taken by Puckett during 2000-2005 (limiting magnitudes ranging from
18.0 to 20.0).  SN 2005ma has a spectrum similar to that of the
type-IIn supernova 1997ab one year after discovery (cf. CBET 334).
Additional magnitudes for 2005mb in NGC 4963:  Dec. 5, [19.6
(Puckett); 22.41, 19.3 (Puckett); 24.71, R = 19.5 (H. Naito, Nishi-
Harima Astronomical Observatory, 2.0-m Nayuta telescope).  A
measurement of Naito's image by S. Kouzuma and H. Yamaoka, Kyushu
University, yields position end figures 52s.315, 59".43 (rms
residuals about 0".2) for 2005mb.  Yamaoka adds that a Digitized
Sky Survey (DSS) image taken on 1990 Jan. 25 shows nothing at the
position of 2005mb (limiting red mag about 20.5).  Nothing was
visible at the location of 2005mb on images taken by Puckett on
numerous dates during 1998-2005 (limiting mag ranging from 18.7 to
20.2).  Additional magnitudes for SN 2005mc in UGC 4414:  Nov. 29,
[18.5 (TNT); Dec. 5.43, [19.5 (Li, KAIT); 24 (in poor seeing) and
25.63, 16.5 (TNT).  SN 2005mc is a type-Ia supernova (cf. CBETs 334,
338).  Additional magnitudes for SN 2005md in NGC 2274:  Dec. 10.40,
[19.5 (KAIT); 25.86, 18.0 (X.-F. Wang and F.-Y. Bian, 0.8-m THCA-
NAOC telescope, Xing-long Station).  Additional magnitudes for SN
2005me in ESO 244-31:  Dec. 2.93, [18.7; 23.806, 17.5; 26.760, 17.6.
SN 2005me is not visible on the DSS (limiting red mag 20.5).
