T CrB in excited state

Post by admin »

T CrB, the recurrent nova (1866 1946) is currently in excited state.

On the recent spectra, for example 19-07-2013, one can see (faints) He I and He II lines :

More spectra should be useful.
Also photometry in B band or clear, with exposure time under 20-30 secondes in order to detect flickering.

Spectra to be sent to Francois.Teyssier at dbmail.com.
