I noticed that the spectroscopy of MWC 560 is continuing - beautiful spectra!

I hope the observations will continue as long as possible, and especially in March when HST re-observations (first half of March), and XMM observations (in second part of March) are planned .


V694 Mon is still very bright.
AAVSO light curve and ARAS spectra (triangles)
A daily coverage is requested until mid-April

All the best,

Hello all,

Between two clouds covers...I finally got a new spectrum of V694 Mon !
The spectrum below was obtained, on March 2 at 21 h 05 TU (Alpy 600, resolution 502, JJ = 2458911.3787, 8 exposures of 300 s) :
Clear skies to all !

Here is my low resolution V0694 Mon spectra from last night (04Mar20):

Lots of interesting absorptions in the blue balmer end. The split absorption/emission figures indicate high gas flow velocities occurring.
Hbeta is almost 1/2 as intense as Halpha.

Message from Margarita Karovska:

Just an update on the MWC 560 upcoming observations:

The HST observations of MWC 560 are scheduled for March 11 2020

and the

XMM observations are currently scheduled for March 22 2020.

An update with an echelle spectrum obtained on 11th of March, the date of HST observation.
The SNR is a little bit low due to cloudy weather
The velocities of the absorptions remain low for this object.

Monitoring continues until mid-April. Daily observations should be a must for this very variable target
