The spectra are in fits format. They are in units of ergs/sec/cm**2/Ang. Wavelengths are in Angstroms. All spectra have been corrected for redshift (z=0.01166, 3498 km/s). There is a group of *opt* files and a group of *ir* files which are the optical and IR spectra, respectively. Also There spectra are the result of glueing spectra covering different wavelengths ranges. In all cases I applied relative grey shifts to avoid discontinouities. These spectra are the result of combining the optical and IR spectra. They may have up to 2 days of difference in their observation epoch. The combination was done by grey-shifting the ir spectra until a good match to the optical spectrum was achieved, although the overlap region was often very narrow. All telluric lines in the IR were removed but the telluric lines blueward of 10000A are still there. Maximum light in B was on JD 2451470. The files are named after the UT date. For a more precise UT observations date check the image headers themselves. Bmax was October 18. Thus assuming late on that day, the explosion was about October 1. Parent Galaxy IC 5179 Sbc diameter 25 mag is 10**1.38*10**-1=2.5'=150'' which doesn't seem right: way to big, the SN would be right in the nucleus ????. v_helio=3498 km/s Hamuy and already corrected for. 3447 IAUC 7272 3407 Asiago 3408 Leda mean central velocity. v_virgo corrected=3261 which leads to 50 Mpc distance for H_0 which is exactly the distance my day 45 fit gives. 66 degrees between polar axis and line of sight (Leda). It could then have host galaxy reddening. A_B=.09 Leda based on Schlegel et al. E(B-V)=A_B/4=.0225 Should it be 4 or 4.1 ???? or something else ??? %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% IAUC A one-at-a-time search finds only two IAUCs on 99ee in 1999 october-november. Since it wasn't a specially noticed Ia, that may be all. 1999 October 9 (7272) Daniel W. E. Green Circular No. 7272 Central Bureau for Astronomical Telegrams SUPERNOVA 1999ee IN IC 5179 J. Maza, University of Chile; and M. Hamuy, University of Arizona, report the discovery by M. Wischnjewsky, on a 20-min unfiltered T-Max 400 film taken by L. Gonzalez on Oct. 7.15 UT with the University of Chile's Maksutov telescope, of a supernova (m_pv about 17.5) located at R.A. = 22h16m09s.40, Decl. = -36o50'31".5 (equinox 2000.0), which is about 10" east and 10" south of the nucleus of IC 5179. The supernova was confirmed by P. Candia from B,V,I images taken with the Cerro Tololo 0.9-m telescope on Oct. 8.12. Maza obtained a spectrum (range 320-800 nm; resolution 0.4 nm) of SN 1999ee on Oct. 9.10 using the 4-m Blanco telescope at Cerro Tololo, which reveals that the supernova is a type-Ia event with the characteristic Si II 635.5-nm line having an expansion velocity of 15 700 km/s. The spectrum has a blue continuum, indicating the supernova to be several days before maximum. Hamuy and C. Lidman obtained a spectrum (range 1000-2200 nm; resolution about 500, S/N about 7) on Oct. 9.10, at the European Southern Observatory with the Very Large Telescope (+ ISAAC), which shows a featureless continuum. At the redshift of the host galaxy (3447 km/s), a type-Ia supernova could reach a peak V magnitude near = 14.5. 1999 October 19 (7284) Daniel W. E. Green Circular No. 7284 Central Bureau for Astronomical Telegrams SUPERNOVA 1999ee IN IC 5179 A. Williams, Perth Observatory, reports that J. Biggs and A. Verveer obtained four unfiltered CCD images of SN 1999ee (cf. IAUC 7272) around Oct. 18.49 UT with the Perth 0.25-m Mike Candy Telescope, yielding the following precise position for the supernova: R.A. = 22h16m10s.00 +/- 0s.02, Decl. = -36o50'39".7 +/- 0".2 (equinox 2000.0; GSC reference stars), which is about 13" east and 3".5 south of the galaxy's center; the magnitude was estimated as 15.5 +/- 0.5.
