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 (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,
