Halpha and Hbeta show a narrow emission on top of an absorption, typical for a dwarf nova outburst. We also identify He II 4686 in emission which indicates that the progenitor system might be a magnetic CV, consistent with the conclusions from ATels 13176 and 13190.

53892019-10-28 23:25:16jburkeJamison Burke, Daichi Hiramatsu, D. Andrew Howell, Curtis McCully, Craig PellegrinoGlobal SN ProjectSN Ia0.0106211Global SN ProjectUsing Superfit (Howell et al. 2005, ApJ, 634, 1190) and SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find best fits to SNe Ia, including SN 2005cf between two weeks and one week before max. The supernova is closest to IC 5173B (z = 0.010621, 20096dF...C...0000J; value from NED). Assuming this redshift, we measure a Si II velocity of approximately 17,000 km/s from the 6347/6371 doublet, and a Ca II velocity of approximately 20,000 km/s from the NIR triplet. The B-band absolute magnitude roughly coeval with the spectrum is approximately -16.8. The absolute magnitude and high velocities indicate that the SN is young. Further followup is encouraged.

Turatto (INAF Osservatorio Astronomico di Padova)Padova-AsiagoCV1Padova-AsiagoThe spectrum shows a blue continuum with narrow Halpha, Hbeta and Hgamma in emission at the rest wavelength. The transient is therefore a cataclysmic variable (CV). The Balmer decrement from the emission components, with the presence of a fairly strong Halpha and higher members of the series showing progressively stronger absorptions, confirms the classification as a dwarf nova. Also the He I emission at 587.6 nm is clearly visible
