COMET C/2009 E1 (ITAGAKI)
     M. Kusiak, Astronomical Observatory, Jagiellonian University,
reports that this comet is apparently visible in SOHO SWAN
ultraviolet images (additional details are given on CBET 1721).
Visual total-magnitude and coma-diameter estimates:  Mar. 14.85 UT,
9.6, 4'.5 (J. J. Gonzalez, Leon, Spain, 0.20-m reflector; zodiacal
light); 15.103, 10:, 3' (A. Hale, Cloudcroft, NM, U.S.A., 41-cm
reflector; clouds; small condensed area within a diffuse coma);
15.95, 9.6, 3'.5 (M. Goiato, Aracatuba, Brazil, 22-cm reflector).
     Further to IAUC 9026, additional astrometry has been published
by B. G. Marsden on MPEC 2009-E69, together with the following
preliminary parabolic orbital elements and an ephemeris.

     T = 2009 Apr.  7.385 TT          Peri. =  47.130
                                      Node  = 105.780   2000.0
     q = 0.60809 AU                   Incl. = 128.398


COMETS C/2008 W2, C/2008 W3, C/2008 W4, C/2008 W5 (SOHO)
     Further to IAUC 9024, additional Kreutz sungrazers have been
found on SOHO website images, with their "discovery" observations
tabulated below.  C/2008 W2 was tiny and condensed (mag about 7.5).
C/2008 W3 was stellar in appearance (mag about 7-7.5) in C3 images,
and quite condensed in C2 images.  C/2008 W4 was tiny and stellar
in appearance (mag about 8).  C/2008 W5 was stellar in appearance
(mag about 6.5) in C3 images, and fairly condensed with a very
short, diffuse tail in C2 images.
