Hello all,

Here is a comparison of two spectra of UV Aur obtained on February 12 (resolution 502, JJ = 2458891.524, 6 exposures of 300 s) and March 30 (resolution 501, JJ = 2458939.3923, 8 exposures of 300 s) with my Alpy 600.

We can note the decrease in the relative intensity of the Halpha line as well as the transition to absorption of the Hbeta line and the modification of the Hgamma line.

Wishing you all in good health and clear skies,
