Two additional supernovae have been discovered on unfiltered CCD images: 2006ds by Y.-S. Tsai and K.-C. Lu (0.40-m reflector, Kenting Star Village Observatory, Hengchun, Taiwan; note spelling correction to Lu's name from the initial report on CBET 580), and 2006dt by N. Lee and W. Li (via LOSS/KAIT; cf. IAUC 8731). SN 2006 UT R.A. (2000.0) Decl. Mag. Offset 2006ds July 18.80 22 55 18.32 -33 55 17.5 16.1 5".4 W, 3".6 S 2006dt July 20.20 14 35 43.11 + 8 17 55.8 16.8 2".9 E, 6".2 S SN 2006ds in PGC 70011 was confirmed at mag about 15.5 on a CCD frame taken by Tsai and Lu on July 19.82 UT; nothing is visible at this location on a Digitized Sky Survey image (limiting red mag 20.5). SN 2006ds is a type-II supernova (spectroscopic details on CBET 580). Additional magnitudes for 2006dt in NGC 5681: July 11.20, [19.0; 15.23, 17.5. SN 2006dt is a type-Ia supernova, near maximum on July 21.22 (details on CBET 582).
