Re: V1448 AQL End of Outburst
Hi Stephane, thank you for notification. I try to capture a spectrum with Lhires III and 1200 l/mm grating, finding (of course) similar intensities to your recent spectrum. Anyway an activity restart, compared with summer 2012, seems clear.
This profile is tellurics removed, I observed through some clouds and with a very humid climate (very bad weather period with thunderstorms every afternoon).
Probably we have to wait to see some evolution.
Clear sky!

Hi Paolo,
Your spectrum has a very good SNR. We see very clearly a disaster recovery, this star seems evolve slowly but surely. There should be more regular spectra to show the rise which seems to me to be an abrupt transition.

Re: V1448 AQL End of Outburst
Emission events can be slow or... fast... that's why it is important to have some good time resolution at R>5000
So, let's keep an eye on this star.
