Astrometry was obtained as follows: 2004 06 17.03532UT RA 20h 36m 06.84s DEC +63 44'12.4" (J2000) Limiting Magnitude on this frame was 19.5. Offsets 45.9"W, 10.6"S. Mark adds there is no trace of the object on his images of 2001 Aug 5 and 2003 July 13 (Limiting magnitude 19.5 for each) nor on POSS-II plates; red 1991.666 (LM 20.8), blue 1992.575 (LM 22.5). A further e-mail of June 19 advised that confirmation of the new object was obtained as follows: 2004 06 18.96456UT End figures: RA 06.83s, DEC 12.3" mag 17.8. R K. Foley et al., University of California, has reported on IAUC 8360 that this object is a supernova of type II. The object was designated supernova 2004cr and announced on IAUC 8359. Congratulations to Mark on the discovery of his 65th supernova. VARIABLE OBJECT IN HERCULES Hitoshi Yamaoka, Kyushu University, Japan, reports that he has obtained a position for this object (cf TA E-Circular 2007) from Itagaki-san's image: RA 18h 39m 26.152s, DEC +26 04' 09.89" (2000). He adds that a 2MASS star (western component of close double) is located about 1" from this position: 2MASS RA 18h 39m 26.19s +26 04' 08.8" J=13.399 H=12.853 K=12.542 (VSNET NewVar 2446) SUPERNOVAE 2004cj-2004cq The above designations relate to the discovery by the SDSS Collaboration of several supernovae detailed on IAUC 8359 from which the brief list below has been extracted: SN 2004 UT R.A.
