One research question Brad Schaefer raised was whether T CrB is a Neon nova. A spectrum from the 1946 eruption suggested it might be. If it is, then it is not a Type 1a SN progenitor. Hence Brad encouraged spectroscopists to look for the appearance of Ne III lines (3869 and 3965 A) 1 week to 1 month post peak eruption.
