Reply To: Preparing for the eruption of T CrB

[Robin Leadbeater]

I managed to squeeze in a high resolution spectrum last night in twilight before it dipped into some trees. The decreasing Equivalent Width of the H alpha emission line reported in ATel #16214

is confirmed by the spectra in the BAA database.

Cheers
Robin
