Abstract (from CDS):

Further to IAUC 8874, published data for objects not yet spectroscopically confirmed appear on the specified CBETs: 2007gw in NGC 4161, CBET 1042 (Corrigendum to CBET 1042: 2006dk was a type-II supernova); 2007ig in MCG -01-5-2, CBET 1060; 2007iq in UGC 3416, CBET 1064; 2007iw in ESO 325-43, CBET 1071; 2007kc in UGC 8400, CBET 1082; 2007kd in MCG +6-21-36, CBET 1083. The spectral type of 2007ir in UGC 2033 is unknown (cf. CBETs 1067, 1077). Data for type-Ia supernovae: 2007hj in NGC 7461, CBET 1048; 2007hu in NGC 6261, CBETs 1056, 1058; 2007if, CBET 1059; 2007is in UGC 10553, CBETs 1067, 1075. SN 2007hb in NGC 819 is a type-Ib/c supernova (cf. CBETs 1043, 1066, 1067). Data for type-II supernovae: 2007hv in UGC 2858 (CBETs 1056 and 1058); 2007il in IC 1704, CBET 1062; 2007it in NGC 5530, CBETs 1065, 1068; 2007iv in UGC 12917, CBETs 1070, 1072. Prediscovery V magnitudes of 2007it from G. Pojmanski (Warsaw University Astronomical Observatory) from All Sky Automated Survey images, somewhat affected by light from the galactic core: Sept. 4.008 UT, [14; 5.994, 12.4; 6.014, 12.0; 8.036, 12.4; 11.027, 12.1; 12.983, 12.3. SNe 2007gx, 2007hl, and 2007hn are also of type Ib or Ic; 2007gy, 2007gz, 2007hc, 2007hi, 2007hm, 2007hr, 2007hs, 2007hw, 2007ib, 2007iu, 2007iz, 2007ja, 2007jf, 2007jm, and 2007jn are of also of type II; the remainder are type-Ia supernovae. SN 2007iu is 10".3 west and 1".3 north of the center of the apparent host galaxy (which is not a star, as stated on CBET 1069). Objects questioned as possible type-Ia supernovae include 2007ie, 2007ii, 2007jc, and 2007jv. Objects questioned as possible type-Ib or -Ic supernovae include 2007jc, 2007ju, and 2007jy.
