     R. J. Beswick, D. Fenech, H. Thrall, M. K. Argo, T. W. B.
Muxlow, and A. Pedlar, Jodrell Bank Observatory, report further
detections of the radio emission from the evolving type-II
supernova 2002hh in NGC 6946 (IAUC 8005, 8018) and limits on the
radio emission from SN 2005V in NGC 2146.  Very Large Array 'B'-
configuration observations of 2002hh detected flux densities of
0.35 +/- 0.1 mJy at 4.860 GHz on 2003 Nov. 14 and 1.6 +/- 0.2 mJy
at 1.425 GHz on 2005 Apr. 16 at R.A. = 20h34m44s.25, Decl. =
+60o07'19".4 (equinox 2000.0; +/- 0".2 in each coordinate), in
close agreement with previously reported positions.  MERLIN
observations place 3-sigma upper limits for the type-Ib/c supernova
2005V (cf. IAUC 8474) on 2005 Apr. 4 of 0.14 mJy at 1.658 GHz, and
on May 19 of 0.23 mJy at 1.408 GHz at the reported position.
Further observations of both sources are underway.

COMETS C/2005 L14, C/2005 L15, C/2005 M2-M5 (SOHO)
     Five more tailless Kreutz sungrazing comets, and one elongated
'non-group' comet (C/2005 M3), have been found on SOHO images (cf.
IAUC 8570; JZ = J. Zhang).  C/2005 L14 was tiny and at the
background noise level.  C/2005 L15 was stellar and relatively
bright, reaching mag about 5.0 at 9.1 solar radii on June 16.512 UT.
C/2005 M2 appeared very small and stellar in C3 images but slightly
diffuse in C2 images, reaching mag about 6.8 at 7.6 solar radii on
June 16.592.  C/2005 M3 reached mag about 7.6 at 7.3 solar radii on
June 19.700.  C/2005 M4 was diffuse, reaching mag about 7.7 at 7.9
solar radii on June 20.783.  C/2005 M5 was very diffuse, reaching
mag about 8.2 at 7.6 solar radii on June 21.033.

     Further to IAUC 8558, J. McGaha revises his report concerning
images obtained with the 0.62-m f/5.1 reflector to note the
following increases in R magnitude (estimated uncertainty +/- 0.05
mag) seen in the stated photometric aperture sizes:  3", 1.48; 10",
1.33; 16", 0.99; 32", 0.64.
