AZ Cas at 3rd contact

[Robin Leadbeater]

A reminder that AZ Cas should have reached 3rd contact on 27/28 February. As of last night the AAVSO data is not showing any increase yet though. I have spectra to reduce for 18,19,26,27 Feb at the Ca H/K line region

Cheers

It looks like 3rd contact was yesterday and egress has begun.

I got 2 more observations on 1, 2 March but the run of good weather is now over

Cheers

buona fortuna

Merci François!

I think the true miracle are the Robin Ca H/K line region spectra...

Ciao!

The attached spectra were taken at predicted 3rd contact and tonight. Also included is an earlier one taken pre eclipse. The spectrum has not yet returned completely to the pre eclipse condition.

Cheers
