Here is my old spectra from late January2019 (Alpy600 & LISA-Ir combined):

Will shoot it again...most likely from Mt. Pinos, CA 3 weeks from now because my east sky has too much obstruction.

Thank you François !

I hope to take advantage of a "break" through the clouds in the coming days to obtain a new spectrum of AX Per and, perhaps, detect the reappearance of the [FeVII] line at 6087A...
It's really exciting to see how evolve this binary system over the weeks !

Hello James,

Very interesting to discover the spectrum of AX Per in the infrared !
How did you go about combining the spectra of your Alpy and your LISA ?
I also have an east horizon little cleared from my garden...with a small "window" to observe !
I hope that we can be more numerous to be able to continue the monitoring of AX Per in the morning sky !

Spectroscopically...and clear skies !

Hello all,

Finally, the clouds left me a small window of observation in the morning sky...
The spectrum below was obtained on June 13 at 00 h 50 TU (Alpy 600, resolution 503, JJ = 2458647.5352, 4 exposures of 300 s) :

Comparison of the spectra of May 12, June 1 and June 13 :
AX Per on May 12th, June 1st and June 13th, 2019 (identification of some lines from PlotSpectra)
AX Per on May 12th, June 1st and June 13th, 2019 (identification of some lines from PlotSpectra)
AX Per on May 12th, June 1st and June 13th, 2019 (zoom)
AX Per on May 12th, June 1st and June 13th, 2019 (zoom)
The decrease of the relative intensities of the spectral lines continues and... no sign of reappearance of the [FeVII] line at 6087A for the moment !

Clear skies,

Hello all,

This is my last update for AX Per !
The spectrum below was obtained on June 21 at 23 h 38 TU (Alpy 600, resolution 507, JJ = 2458656.485, 4 exposures of 300 s) :
AX Per on June 21th, 2019

AX Per on June 1st, June 13th and June 21th, 2019 (identification of some lines from PlotSpectra)

AX Per on June 1st, June 13th and June 21th, 2019 (zoom)
The relative intensities of the spectral lines have changed very little since June 13th (no sign of reappearance of the [FeVII] line at 6087A).

Clear skies,

Hello all,

With a little delay due to busy weeks, here is my last update for AX Per with two new spectra !

The first one was obtained on June 26 at 23 h 48 TU (Alpy 600, resolution 505, JJ = 2458661.4921, 12 exposures of 300 s) :
AX Per on June 26th, 2019

The second spectrum below was obtained on July 5 at 22 h 36 TU (Alpy 600, resolution 506, JJ = 2458670.4423, 14 exposures of 300 s) :
AX Per on July 5th, 2019

Comparison of the spectra of June 21, June 26 and July 5 :
AX Per on June 21th, June 26th and July 5th, 2019 (identification of some lines from PlotSpectra)
AX Per on June 21th, June 26th and July 5th, 2019 (identification of some lines from PlotSpectra)
AX Per on June 21th, June 26th and July 5th, 2019 (zoom)
AX Per on June 21th, June 26th and July 5th, 2019 (zoom)
For example, we can notice the increase in the relative intensity of the Halpha line between June 26th and July 5th, but still no sign of reappearance of the [FeVII] line at 6087A...
