Supernovae 2002fc, 2002fd, 2002fe, 2002ff, 2002fg, 2002fh
Abstract
N. Yasuda, National Astronomical Observatory of Japan, on behalf of the Supernova Cosmology Project (cf. IAUC 7763 and 7764, plus V. Prasad, G. Sainton, E. Smith, and A. Spadafora) and the Subaru high-redshift supernova search group (M. Doi, K. Nariai, M. Watanabe, Y. Urata, Y. Komiyama, N. Kashikawa, T. Yamada, M. Ouchi, T. Murayama, K. Shimasaku, H. Furusawa), reports the discovery of six supernovae found with the Subaru telescope (+ prime-focus Suprime-Cam). Nothing was visible at the respective positions to limiting magnitude i' about 26.0 on images taken on Apr. 9 (SN 2002fh), 12 (SN 2002fg), and Mar. 19 (the rest). SN 2002 UT R.A.

The supernova spectra were obtained at the Very Large Telescope on Apr. 11 and June 5; at the Gemini telescope on Apr. 16, May 11, and June 5; and at the Subaru telescope on Apr. 16. The redshifts were determined from host-galaxy emission and absorption lines, and all the supernovae were found to be within 2" of their host-galaxies' centers. Photometry was also obtained with the Hubble Space Telescope during Apr. 23-July 3 for SNe 2002fc, 2002fe, 2002ff, and 2002fg.
