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.

The evolution of the spectrum profile is compatible with the light curve :
Light curve of GK Per (Johnson V : green squares) (AAVSO)

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