Darryl Sergisson thanks the observers who contributed to the trial campaign in 2012 : Christian Buil, Stéphane Charbonnel, François Teyssier, Thierry Lemoult, Robin Leadbeater, Thierry Garrel, Andrew Smith.

After reviewing the collected spectra, Darryl propose concentrating efforts on

RY Tau at high resolution ( R > 10000) for eShel, Lhires III 2400 l/mm ...
V410 Tau at lower resolution (R ~ 2000) Lhires III 600 l/mm, trials with Lisa and Alpy600

The objectives and methods are described in the updated ARAS page for T Tauri stars campaigns (with the results of 2012 campaign) : http://www.astrosurf.com/aras/Aras_TTauri/T_Tauri_Campaign.html

François, Do we yet know if LISA R=1000 (or APLY) spectra of V410 are of interest? Thanks Andrew

Yes Andrew
This the target for low resolution :
"It would be great if observers with lower resolution spectrographs would monitor another star, V410 Tau which is bright (R = 8.5) and thought to have significant coverage of star spots"
(Darryl Sergisson)

BUT,

1. V410 Tau is currently at mag 11 and is a difficult target. I tried it during OHP Star party, not impossible, but difficult to get deatails
2. No news from Darryl Sergisson.

I'll try to join him next week-end and let you know

All the best
