Garradd reports his discovery of a diffuse comet on images taken with the 0.5-m Uppsala Schmidt telescope in the course of the Siding Spring Survey (discovery observation below). Follow- up observations by R. H. McNaught on June 6.4 UT show a 15" tail in p.a. 150 deg. 2006 UT R.A. (2000) Decl. Mag.

IAUC 8718) -- all being Kreutz sungrazers except C/2006 K5 (no known group). C/2006 J1 was very small, slightly diffuse, and too faint for photometry. C/2006 J2 was small, stellar, and faint (mag about 8.0). C/2006 J3 was slightly diffuse and reached mag 7.7 on May 4.496 at 6.4 solar radii; it showed a 162" tail on May 4.538 at 5.9 solar radii. C/2006 K5 was extremely faint, peaking at mag about 8.5 at May 22.196, and measurer K. Battams could only find it in about 10 images. Corrigendum: C/2006 G3 was found by J. Sachs, not H. Su (cf. IAUC 8717). Comet 2006 UT R.A.(2000)Decl. Inst.
