     Further to IAUC 8573, R. Kracht reports another comet found
and measured by himself from SOLWIND images.

The following parabolic orbital elements are by B. G. Marsden.  The
comet seems not to belong to a known group.

     T = 1984 Sept.17.42 TT           Peri. =  78.74
                                      Node  = 152.84    2000.0
     q = 0.1051 AU                    Incl. =  36.92


SUPERNOVA 2005dh in MCG +04-37-55
     Further to IAUC 8580, M. Moore and W. Li report the LOSS
discovery of an apparent supernova on unfiltered KAIT images taken
on Aug. 10.22 (at mag 17.1) and 11.23 UT (mag 16.9).  SN 2005dh is
located at R.A. = 15h54m03s.32, Decl. = +23o08'09".9 (equinox
2000.0), which is 6".1 east and 16".4 north of the nucleus of MCG
+04-37-55.  A KAIT image taken on Aug. 1.20 showed nothing at this
position (limiting mag about 19.0).
