Good morning to everybody.
As per François Teyssier alert in [spectro-l], here below our spectrum taken on 22/10/2014 around 19:00 UT of the star VSX J213806.5+261957.
Unfortunately the sky was strongly spoiled by clouds and veils and this has compromised the SNR of our images.
The target has been calibrated using a Miles star F class. We would have preferred to use a reference star with more blue spectrum but unfortunately the weather condition obliged us to be as fast as possible in collecting the reference spectrum. So we have choosen the closest and brightest available star from Miles catalogue.

Here the weather is very variable, we hope someone else will be able to collect further spectra.

Regards

Note: the 20141025_332 name has a 12-hours skew error - came from OrionStudio's time field limited by 12-hours without any AM/PM info, disagreeing with my script that fixes date field to make ISIS runnable and was guessing AM/PM wrongly...so that was taken around 10.25 7:00 PM too - sorry for this error!
