We have already received several responses from those interested in assisting with this project. Some visual observers have asked if they could participate and I would not rule this out at this stage except we are ideally looking at those with large telescopes which would enable objects of, say, magnitude 15 to be observed. SUPERNOVA 2000cs IN MCG +7-34-15 T. Puckett, Mountain Town, GA, reports the discovery of an apparent supernova (mag 17.8) on an unfiltered CCD frame (limiting mag 20.5) taken with the Puckett Observatory 0.60-m automated supernova patrol telescope on June 30.25 UT. The candidate is located at R.A. = 16h23m32s.24, Decl.= +39o07'29".1 (2000), which is 5".5 west and 11".9 north of the centre of MCG +7-34-15. The new object was also present on an unfiltered CCD frame taken by Puckett on July 1.13. The candidate was also confirmed by J. Newton, Newton Observatory B & B, Osoyoss, BC, on unfiltered CCD images taken with a 0.40-m refelctor on July 1.23. IAUC 7446 (extract) SUPERNOVA 2000ct IN ANONYMOUS GALAXY T. Puckett, Mountain Town, GA; A. Sehgal, Woodinville, WA; and J.Newton, Osoyoos, BC, report their discovery of an apparent supernova (mag 17.5) on an unfiltered CCD frame (limiting mag 20.5) taken with the Puckett Observatory 0.60-m automated supernova patrol telescope on July 4.13 UT. The candidate is located at R.A. = 17h01m03s.64, Decl. = +33o28'45".0 (2000), which is 7".0 west and 13".4 north of the centre of the host galaxy. The new object was also present on an unfiltered CCD frame taken with the 0.40-m reflector at the Newton Observatory B & B on July 6.55 UT. IAUC 7448 (extract) NOVA IN THE LARGE MAGELLANIC CLOUD 2000 W. Liller, Vina del Mar, Chile, reports his discovery of an apparent nova in the Large Magellanic Cloud on two unfiltered Kodak Technical Pan films obtained using a 0.2-m Schmidt camera on July 12.4 UT. The object was not present on a film he had taken of the region on 1999 Mar. 8. On July 13.0, using a CCD at the Schmidt's Newtonian focus, he measured the object's position as R.A. = 5h25m01s.60, Decl. = -70o14'17".3 (2000). Observed magnitudes: July 12.4098 UT, 11.2 (Liller); 12.4129, 11.2 (Liller); 12.98, V = 11.45 (Liller, comparison GSC 9166.0178); 13.469, mv = 11.8 (R.Stubbings, Drouin, Vic., Australia, comparison GSC 9166.0673; VY Hyi sequence suggests mv = 12.2).
