Hello all,
GK Per is in the boundary of my equipment detection, but it's possible that despite the noise the graphic would still be useful.
Cheers, Joan Guarro.

Hello all,
I obtained a new spectrum of GK Per with my Alpy 600 on 15 February at 20:28 UT (resolution of 520, JJ = 2459991.3942) with an acquisition time of 80 min (8 x 600s) :
- GK Per on February 15th, 2023
- _gkper_20230215_894_Christophe Boussin_3700_7565.png (93.14 KiB) Viewed 4250 times
- GK Per on February 7th, 12th and 15th, 2023 (identification of some lines from PlotSpectra)
The evolution of the spectrum profile is compatible with the light curve :
- Light curve of GK Per (Johnson V : green squares) (AAVSO)
Clear skies to all !!

Another spectrum made in 2 parts, and in 2 consecutive days (I could not make it in one night, mist and clouds)
Regards,
