Hello Paul,
Yes, indeed, John Toone has prepared a NE chart and sequence here: https://britastro.org/vss/xchartcat/CrB%20T%20025.04%2050d.JPG
When it erupts, it will transform this part of the sky – briefly. As I comment in the forthcoming October Journal, I dearly hope the eruption is detected by an amateur astronomer.
John has also extended the sequence at the faint end this year, given that T CrB is in the pre-eruption Peltier dip and is currently fading: https://britastro.org/vss/xchartcat/CrB%20T%20025.04%202d.JPG
Go well,
Jeremy
