Had the opportunity to visit a most fascinating solar #observatory Thursday in #Switzerland near #Arosa, the Astrophysikalisches Observatorium #Tschuggen (AOT) which #MaxWaldmeier had built in 1939, which was abandoned in 1980 and which amateur astronomers are now bringing back to the state just at that time: Here are the original Kern #coronagraph and another one from #Zeiss (with a huge spectrograph) it's sitting on.

Two European satellites mimic a total solar eclipse as scientists aim to study its corona.

The satellites have created the first artificial solar eclipse by flying in precise formation, providing hours of on-demand totality for scientists.

Dubbed Proba-3, the €181 million mission has generated 10 successful solar eclipses so far.

ESA released the eclipse pictures at the Paris Air Show on Monday.

Yay, 'live' images from the new solar #coronagraph CCOR-1 are finally available on https://testbed.spaceweather.gov/products/ccor-1-coronagraph though it is still not operational! Can we have another bright small-elongation comet now, please? ;-)
