A 0.35-m Schmidt-Cassegrain telescope was used during searches for the UK Nova/Supernova Patrol. The new object is located at: RA 17h08m04.96s DEC +26 22'44.4" (2000), which is approximately 2.2" west and 0.8" north of the centre of the host galaxy. The suspect is not present on Tom's images of 2004 May 27 and Jun 27 (limiting mag 19.5) and it is not present on DSS II red (1996.239) or blue plates (1990.322). The object has been designated supernova 2004ec and announced on IAUC 8396. Congratulations to Tom on the discovery of his 71st supernova. RS OPHIUCHI B. E. Schaefer, Louisiana State University, reports on IAUC 8396 the discovery of a nova eruption of RS Oph in early 1907. Although in solar conjunction, the outburst has been inferred from a post-eruption dip on photographs in the Harvard Collection.
