     On tonight's astro-ph is a paper (accepted for MNRAS) about the historical lightcurve of T CrB.  This includes AAVSO data plus much previously inaccessible archive data (which ought now to be added to the AID):


The prediction is now that the next full eruption will occur 2025.5 +/- 1.3 years.  The displays of the complete historical data are impressive.  Missing from the paper is a desiderata of what observing should be done between now and the upcoming event (wavelengths, cadence spectra etc), and what would help with the astrophysical interpretation.  Nevertheless I would consider this to be 'required reading' for anyone interested in what happens in the sky.

Re: T CrB new report

That's an interesting analysis: there's a lot of good information there.

I try to catch T CrB each morning - I'm anxiously awaiting its next outburst!  Nice and bright, so it's an easy target, though it's a tight fit getting the only two decently bright field stars on the image with the variable
