POSSIBLE NOVA IN CYGNUS
     S. Nakano, Sumoto, Japan, reports the discovery by H.
Nishimura (Miyawaki, Kakegawa, Japan) of a possible nova (mag 10.5)
on two Kodak T-Max 400 films taken on Apr. 2.807 UT using a Pentax
6x7 camera (+ 200-mm f/4.0 lens; 60-s exposures).  Nishimura
provided the following position for the new object:  R.A. =
21h11m32s, Decl. = +44o48'02" (equinox 2000.0), noting that nothing
was present at this location on his films taken on Mar. 28
(limiting mag 12) or on earlier patrol films back to Oct. 2001.
Following a request to the AAVSO, R. Miles (Stourton Caundle,
Dorset, England) reports a confirmation of the object at V = 8.5
+/- 0.3 on a CCD image taken on Apr. 4.995, providing the following
precise position end figures:  32s.34, 03".9 (uncertainty estimated
as +/- 0".3).  Miles states that nothing is visible at this
location on a Digitized Sky Survey image.  H. Yamaoka, Kyushu
University, notes that a very red star of mag about 14 in several
star catalogues has position end figures about 31s.9, 03".3.


SUPERNOVAE 2006bg, 2006bh, 2006bi, 2006bj
     Four additional apparent supernova have been reported from
unfiltered CCD images:  2006bg and 2006bi by R. Holmes, Charleston,
IL (cf. IAUC 8677; 2006bg with V. Hoette, and 2006bi with H. Devore
and P. Miller); 2006bh by L. A. G. Monard (cf. IAUC 8693); and
2006bj by R. Quimby (cf. IAUC 8680).

SN      2006 UT      R.A.  (2000.0)  Decl.    Mag.     Offset
2006bg  Mar. 27.28  11 35 25.17  +54 57 37.4  18.4  16".5 W, 2".3 N
2006bh  Apr.  2.12  22 40 16.10  -66 29 06.3  14.8  48" W, 22" S
2006bi  Mar. 25.39  13 59 11.52  +27 52 17.5  18.1  0".2 W, 2".6 N
2006bj  Mar. 26.19  12 22 19.16  + 7 37 25.3  17.3  1".1 E, 1".1 N

Additional approximate magnitudes for 2006bg:  1993 Apr. 25, [21.0
(Palomar Sky Survey, red); 2006 Jan. 26.38 UT, [20.4 (Holmes); Apr.
2.18, 18.3 (Holmes).  Additional magnitudes for 2006bh in NGC 7329:
Jan. 17.751, [17.5; Apr. 3.086, 14.6 +/- 0.1.  Nothing is visible
at the location of 2006bh on the Digitized Sky Survey (limiting red
mag 20.5).  Additional magnitudes for 2006bi:  1996 July 8, [21.0
(PSS, red); 2006 Feb. 19 and 24, [20.2 (Holmes); Mar. 27.31, 18.2
(Holmes).  Additional approximate magnitudes for 2006bj:  2005 May
9, [19.0; 2006 Apr. 2.17, 17.2.  A spectrum of 2006bj taken on Mar.
3.34 by S. C. Odewahn and F. Deglman shows it to be a young type-II
supernova (details on CBET 460).
