Please direct any urgent queries (discoveries) to Nick James or Denis Buczynski. (Contact details in TA). SUPERNOVAE 2000R, 2000S, 2000T, 2000U, 2000V, 2000W, 2000X A. Amadon and G. Blanc, Service de Physique des Particules (SPP), Centre d'Etude de Saclay (CES); J. Haissinski, Laboratoire de l'Accelerateur Lineaire, Orsay; and J. Rich, SPP/CES, on behalf of the EROS collaboration, report the discovery of seven supernovae discovered in the course of the automated supernovae search with the European Southern Observatory (ESO) 1-m Marly telescope at La Silla (limiting mag about 21.5). Each supernova was found by subtraction of CCD images from reference images taken one year ago. SN 2000 UT R.A. (2000.0) Decl.

E. Schaefer, Yale University, on behalf of the QUEST collaboration (see Schaefer et al. 1999, Ap.J. 524, L103), reports on 22 apparent supernovae discovered with the QUEST 16-CCD array camera on the Centro de Investigaciones de Astronomia 1-m Schmidt telescope at Llano del Hato, Venezuela. The total area searched was 264 deg^2 between Mar. 1 and 15 to R = 20.8, with each clear night receiving independent drift scans through B, V, and R filters, so that the 22 objects all have well-sampled 3-color light curves over roughly two weeks. Each apparent supernova was found by subtraction of QUEST reference images taken on five nights between Feb. 8 and 14 and each new object has been confirmed via images taken on four or more nights in March. Five of the objects have no apparent host galaxy, to R about 21.5. IAUC 7387 (extract) Editor: Further details can be supplied on request but all are very faint! SUPERNOVA 2000au IN MCG +8-15-14 T. Puckett and A. Langoussis, Mountain Town, GA, report the discovery of an apparent supernova (mag 17.9) on an unfiltered CCD frame (limiting mag 19.3) taken with the Puckett Observatory 0.35-m automated supernova patrol telescope on Mar. 28.16 UT. SN 2000au candidate is located at R.A. = 7h53m08s.40, Decl. = +50o07'35".3 (2000), which is 5".1 west and 14".5 south of the centre of MCG +8-15-14. SN 2000au was also present on an unfiltered CCD frame taken on Mar. 29.05, but it does not appear on an unfiltered image taken on Feb. 29.15, neither does the object appear on Palomar Sky Survey images taken on 1998 Mar. 24 (limiting mag about 21.0) and 1954 Dec. 30 (limiting mag about 20.0).
