BD+59 250 in emission

Post by Paolo Berardi »

Hi all, it seems that the star BD+59 250 is now in active status. The previous spectrum on BeSS (july 2012, low-res) shows the H-alpha line in absorption.

Thank you Umberto. H-alpha and H-beta lines change in comparison to the old spectrum is clear in your profile.
