The deployment of the immense prominence of May 23 for 135 minutes! 😎
Watch it in full screen and compare to Earth to scale!

This is also applicable to partial solar eclipses: the part of the Moon not covering the solar disk is invisible and undetectable.
So, any dark disk outside the Sun is just a Photoshop drawing!

Here's a transit of the ISS I took in 2015
As depicted here, the ISS is visible over the solar disk but not over the "sky background" (which is not the corona but only atmospheric and instrumental glow)
That's PHYSICALLY IMPOSSIBLE! 🤔

Today's huge and fast prominence, only 15 minutes between each of those images! 😎

@Space_Vagabond yes! thanks for the warning!

I did not want to miss Saturday's occultation of Saturn, it was the last one until 2031! So I traveled to Tarragona, Spain 😊
The star besides Saturn is 85 Aquarius (mag 6.7)

@curiosityonx you have used my photo while removing the copyright. It's illegal. It's robbery.

My last shot of Tsuchinshan-ATLAS on Thursday from Maspalomas dunes (Gran Canaria), with a view of the lighthouse 😊

It's amazing to see how fast the comet moved away from Earth, just three days after my Monday shot in La Palma! 😲

Tsuchishan-ATLAS tonight with its tail and anti-tail over the huge Magic telescopes at La Palma observatory, Canary islands 😊

Giant X4.5-class flare in AR3825 today! 😍
Just 15 minutes before this image, the flare ejected matter visible on the left at very high speed: 400 km/s!

Magnificent prominences today including huge loops! 😎

@frizbee12 c'est déjà quasiment la résolution maxi

[Thierry Legault @ThierryLegault]

The Moon, Saturn...and the ISS! 😎
After the May 31 occultation from Argentina, I wanted something more challenging! 😁
I decided to install my telescope in Spain, in a precise place near the Almendra dam in Castilla&Leon to catch the ISS just 30 min after the occultation 😜
