Note that Marilena means "2003bu" on the last entry, not "2002bu". -------- Original Message -------- Date: Tue, 25 Mar 2003 05:40:52 +1100 (EST) From: Marilena Salvo Dear All, we have just sent these spectral confirmations to Dan Green. Regards, Marilena Salvo P.S. SN 2003bu, the Ic, looked quite bright (mag.~16 or so) for its redshift... -- SUPERNOVA 2003ch in UGC 3787 M.Salvo, B. Schmidt, Research School of Astronomy and Astrophysics, The Australian National University (ANU), and J. Tonry, Institute for Astronomy, The University of Hawaii, report that a spectrum (range 350-900 nm) of SN 2003ch (cf. IAUC 8097), obtained on March 24.45 UT with the ANU 2.3-m telescope (+ DBS spectrograph), shows it to be a Type Ia supernova. Cross correlation with a library of SN Ia spectra indicates the SN is approximately 3 +/- 2 days before maximum light, and at a redshift of z=0.025. SUPERNOVA 2003bn in an Anonymous Galaxy M.Salvo, B. Schmidt, Research School of Astronomy and Astrophysics, The Australian National University (ANU), and J. Tonry, Institute for Astronomy, The University of Hawaii, report that a spectrum (range 350-900 nm) of SN 2003bn (cf. IAUC 8088), obtained on March 24.48 UT with the ANU 2.3-m telescope (+ DBS spectrograph), shows it to be a Type II supernova, approximately 1 month past explosion. The redshift of the host galaxy is cz=3800 km/s as determined from narrow Halpha at the position of the supernova. Weak Iron lines in the SN spectrum indicate a photospheric velocity of 5400 km/s. SUPERNOVA 2003cb in NGC 4885 M.Salvo, B. Schmidt, Research School of Astronomy and Astrophysics, The Australian National University (ANU), and J. Tonry, Institute for Astronomy, The University of Hawaii, report that a spectrum (range 350-900 nm) of SN 2003cb (cf. IAUC 8088), obtained on March 24.64 UT with the ANU 2.3-m telescope (+ DBS spectrograph), shows it to be a Type II supernova, approximately 2 months after explosion. Weak lines in the SN spectrum indicate a photospheric velocity of 3000 km/s. SUPERNOVA 2002bu in NGC 5393 M.Salvo, B. Schmidt, Research School of Astronomy and Astrophysics, The Australian National University (ANU), and John Tonry, Institute for Astronomy, The University of Hawaii, report that a spectrum (range 350-900 nm) of SN 2002bu (cf. IAUC 8092), obtained on March 24.68 UT with the ANU 2.3-m telescope (+ DBS spectrograph), shows it to be a Type Ic supernova. Cross correlation with a library of SN Ic spectra indicates the SN is approximately one week past maximum light.
