New observations scheduled: HST and XMM

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.

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

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
