SN 2009lz was observed on Nov. 9.02 UT; cross-correlation with a library of supernova spectra using the "Supernova Identification" code (Blondin and Tonry 2007, Ap.J. 666, 1024) showed 2009lz to be a type-IIp supernova most similar to SN 2006bp at seven days past maximum light with redshift z = 0.05. 2009lz has evidence for a faint, uncatalogued host galaxy in Sloan Digital Sky Survey (SDSS) images. Additional CSS magnitudes for 2009lz: Sept. 10.45, [20.1; Oct. 10.19, 19.0. SN 2009ma was observed on Nov. 8.36 and exhibits the strong narrow Balmer lines of a type-IIn supernova at z = 0.089. SN 2009ma has no host galaxy visible in Digitized Sky Survey, Palomar Quest, and SDSS images; additional CSS magnitudes for 2009ma: Apr. 20.13, [20.5; Nov. 21.51, 18.7. SN 2009mb was observed on Nov. 16.64 and found to exhibit strong Balmar lines, clearly showing it to be a type-IIn supernova at redshift z = 0.154. The host galaxy of 2009mb is seen in SDSS images and has Gunn magnitudes u = 24.0, g = 22.8, r = 21.7, i = 21.5, z = 21.2; additional CSS magnitudes for 2009mb: May 26.17, [20.2; Oct. 24.50, 19.1.
