  1. Here is a still from a video Sergei Shestov just showed at the CU Boulder #coronographs symposium, from #Proba3 - you can see the remains of an eruptive #prominence in the corona to the lower right of the Sun, on 21 September 2025 at 23:21 UTC.

  7. 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.

    "The mission’s two spacecraft – which will manoeuvre precisely in Earth orbit so that one casts a shadow onto the other – have departed the facilities of Redwire Space in Kruibeke, Belgium. The pair will be flown to the Satish Dhawan Space Centre, near Chennai, for the launch campaign to begin."

  25. (Contd.)

    With key test done, Proba-3 will be shipped to SDSC-SHAR in India on 21 October for a planned launch by PSLV-XL launcher on 29 November 2024.

  26. I've been following this #ESA mission since 14 (!) years when 'around 2012' was the projected launch date (see skyweek.wordpress.com/2009/07/ for what I wrote in 2009) ... and now the two spacecraft making up the #Proba3 mission are actually finished and should launch in 2024: esa.int/Enabling_Support/Space - they'll fly in formation forming a huge solar #coronagraph with one being the occulter and the other observing the #corona of the #Sun.
