Circular No. 8019 SUPERNOVA 2002ic Wood-Vasey et al. also report the discovery of another apparent supernova (mag 18.5) on unfiltered NEAT images taken on Nov. 13 UT. Confirming NEAT observations were made on Nov. 20 (mag >17.8). SN 2002ic is located at R.A. = 1h30m02s.55, Decl. = >+21o53'06".9 (equinox 2000.0), which is 3".6 west of the center of the apparent host galaxy. No point source is visible at this location in previous NEAT Haleakala images taken on Oct. 30 (limiting mag 20.0 at S/N = 3). 2002 November 20 (8019) Circular No. 8028 SUPERNOVA 2002ic Further to IAUC 8027, M. Hamuy reports that a spectrogram (range 320-920 nm), taken on Nov. 29.11 UT by J. Maza and M. Phillips with the Baade telescope, shows that SN 2002ic (cf. IAUC 8019) is a type-Ia supernova. The spectrum reveals strong Fe III absorption features and a weak Si II 635.5-nm line, similar to the peculiar SN 1999ac near maximum light; superimposed narrow emission lines yield a redshift of 0.066. 2002 December 7 (8028) 8151 SUPERNOVA 2002ic 2003jun14 M. Hamuy and M. Phillips, Carnegie Observatories; N. Suntzeff, Cerro Tololo Inter-American Observatory; and J. Maza, University of Chile, report that spectroscopic observations (range 380-930 nm) of SN 2002ic (cf. IAUC 8019), obtained between 2002 Nov. 29 and 2003 Jan. 27 with the Baade telescope (+ Boller & Chivens spectrograph) and the Dupont telescope (+ WFCCD), show a persistent, strong H_alpha emission and a weaker H_beta emission. The H_alpha profile exhibits a double component, one unresolved (FWHM < 300 km/s) and the other with FWHM about 1800 km/s -- both of which remained strong over the first two months of evolution. This feature is reminiscent of type-IIn supernovae and suggests that this is the first detection of interaction between the ejecta of a type-Ia supernova (cf. IAUC 8028) and a hydrogen-rich circumstellar medium. Hamuy et al. add that SN 2002ic is about to reappear from behind the sun, so further observations are urged in order to check or rule out this possibility. 8157 2003jun26 SUPERNOVA 2002ic E. Berger and A. M. Soderberg, California Institute of Technology; and D. A. Frail, National Radio Astronomy Observatory, report an upper limit of 0.1 mJy from an observation of SN 2002ic (IAUC 8019) with the Very Large Array (VLA) at 4.86 GHz on June 16.60 UT; this result is consistent with the dense circumstellar material inferred from H_alpha (IAUC 8151). Further to IAUC 8153, C. J. Stockdale, R. A. Sramek, K. W. Weiler, S. D. Van Dyk, and N. Panagia, report a search with the VLA for radio emission from the type-Ia supernova 2002ic (IAUC 8019, 8028, 8151), possibly the first type-Ia event found showing significant interaction between the ejecta and a dense circumstellar medium: "Hamuy et al. (2003, http://xxx.lanl.gov/abs/astro-ph/?0306270), suggest a similarity to type-IIn supernovae. Our 3-sigma upper limit of 1.28 mJy was obtained at 22.485 GHz (wavelength 1.3 cm) on June 17.79 UT (supernova age approximately 216 days) in 'A'-configuration at the optical position (IAUC 8019). Comparison with the radio emission from the type-IIn supernova 1988Z (and the very similar SN 1986J) indicates that SN 1988Z, at the distance of SN 2002ic, would have yielded a 5-sigma detection at this frequency and epoch (cf. Williams et al. 2002, Ap.J. 581, 396). If SN 2002ic were indeed similar to a type-IIn supernova, lower frequencies would be optically thick at this epoch of observation, as is implied by the upper limit obtained by Berger et al. (see above) at 4.86 GHz on the same date. Additional observations are planned." IAUC 8161 2003jul01 (probably, but that one is still under the ban) SUPERNOVA 2002ic K. S. Kawabata, Y. Ohyama and the FOCAS team, National Astronomical Observatory of Japan; K. Nomoto, University of Tokyo; P. Mazzali, Trieste Observatory; L. Wang, Lawrence Berkeley National Laboratory, write "We carried out optical spectropolarimetry (range 380-1020 nm) of SN 2002ic (initially classified as type Ia; IAUC 8019, 8028, 8151, 8157) on Jun 27.6 UT with the Subaru 8.2-m telescope (+ FOCAS). SN 2002ic is bright (R~19) and still shows a strong H-alpha emission line (FWHM~6nm) and a weaker H-beta emission line (H-alfa/H-beta flux ratio is about 16). A broad and strong Ca II triplet emission is also seen. The spectrum has an apparent similarity to that of the peculiar SN IIn 1997cy between about 100 and 250 days after the explosion (e.g., Turatto et al. 2000, Ap.J., 534, L57), which is consistent with the metamorphosis observed in the earlier phase (IAUC 8151). The depolarization across the H-alpha emission is distinct, which indicates that this SN has a considerable intrinsic polarization (p>1%) at some wavelength regions. The spectrum of the SN is dominated by the interaction region and appears similar to a SN IIn spectrum.
