POSSIBLE NOVA IN PYXIS
     G. Pojmanski, Warsaw University Astronomical Observatory,
reports the discovery, via the All Sky Automated Survey (65-mm-
aperture telephoto lens), of a possible nova located at R.A. =
9h18m58s, Decl. = -29o42'36" (equinox 2000.0).  ASAS V magnitudes:
Mar. 5.259 UT, [14.0; 11.191, 12.0; 14.260, 12.4; 15.00, 12.6;
16.00, 12.8.  H. Yamaoka, Kyushu University, reports the
independent discovery by H. Haseda, Aichi, Japan, at mag 13.3 on
Mar. 16.45 (0.10-m twin patrol camera), providing also the
following position end figures by K. Itagaki (Teppo-cho, Yamagata,
Japan, 0.60-m reflector) from his own unfiltered CCD image taken on
Mar. 16.451:  58s.50, 37".0 (red mag 12.8).  Yamaoka adds that this
position is close to the northern star (blue mag about 18.0) of a
close double on the Digitized Sky Survey.


COMET 141P/MACHHOLZ
     This comet has been recovered at low altitude on CCD images
obtained by M. Jaeger (Stixendorf, Austria, 0.20-m Schmidt
reflector; Feb. 27.8, 28.8, Mar. 1.8, and 13.8 UT) and by K. Kadota
(Ageo, Japan, 0.25-m reflector; Mar. 16.4).  Total visual magnitude
estimates in zodiacal light:  Mar. 9.10, 12.3 (A. Hale, Cloudcroft,
NM, 0.41-m refl.); 11.83, 11.7 (J. J. Gonzalez, Leon, Spain, 0.20-m
refl.).  The following orbital elements, which appear with the
astrometry on MPEC 2005-F08, assume this to be component A (with
nongravitational parameters A_1 = -0.27 +/- 0.03, A_2 = +0.0100 +/-
0.0002; the total magnitudes in the ephemeris below assume H_30 =
14.0).
