NOVA IN THE LARGE MAGELLANIC CLOUD 2009 No. 2
     W. Liller, Vina del Mar, Chile, reports the discovery of an
apparent nova (mag approximately 12.1) in the Large Magellanic
Cloud from two photographs taken with Kodak Technical Pan film on
May 4.994 UT, the position given as R.A. = 5h31m28s +/- 3s, Decl. =
-67o05'38" +/- 8" (equinox 2000.0).  No star brighter than mag
about 19 appears at this position on a U.K. Schmidt image of the
field, and nothing brighter than mag 14.0 was visible on Liller's
photograph from 2009 Apr. 23.01.  L. A. G. Monard, Pretoria, South
Africa, reports a confirmation of the presumed nova at unfiltered
mag 12.5 on CCD images taken under less-than-ideal conditions on
May 7.716, the position end figures measured as 26s.42, 39".4,
adding that no star is visible at this position on the Digitized
Sky Survey (limiting red mag 20), though there is a star of red mag
approximately 18.5 located about 1" southwest of the new object.


2009 HC_82
     Another minor planet in a retrograde orbit but showing no
apparent cometary features has been discovered (cf. MPEC 2009-J04)
by the Catalina Sky Survey.  The following orbital elements are
from MPO 157545:

                    Epoch = 2009 June 18.0 TT
     T = 2008 Nov.  3.8564 TT         Peri. = 296.5814
     e = 0.810058                     Node  = 294.6157  2000.0
     q = 0.463311 AU                  Incl. = 154.5642
       a =  2.439225 AU    n = 0.2587178    P =   3.810 years


COMETS C/2009 A2, C/2009 A3, C/2009 A4, C/2009 A5 (SOHO)
     Further to IAUC 9039, additional Kreutz sungrazers have been
found on SOHO website images, being tiny and stellar in appearance
(peak mag about 7.5, except C/2009 A2 at mag about 7) in C3 images.
C/2009 A3 was small and "roughly stellar" in C2 images.  All except
C/2009 A2 (condensed, and teardrop-shaped) were slightly diffuse
and elongated (peak mag about 11, except C/2009 A2 and A3 at mag
about 10) in STEREO HI1-A images.
