Na een maand van stilte belt Proba-3 weer naar huis
Een satelliet die kunstmatige zonsverduisteringen in de ruimte genereert heeft na een maand stilte contact opgenomen met zijn beheerders.

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. See https://www.facebook.com/media/set/?vanity=dan.fischer.393&set=a.10230945670040155 for a picture album, with links to the background in the first comment.

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? ;-)

How the new #coronagraph #CCOR-1 on a weather satellite saw #comet Tsuchinshan-ATLAS: the view on 8 October at 21:45 UTC, grabbed from the new video https://www.youtube.com/watch?v=QrzOKAxu1jU - the images themselves (more are seen on a computer screen later in the video) don't seem to be available directly yet.

Detecting the K (!) corona with a homemade #coronagraph - apparently this unexpected breakthrough has just been achieved ... in New York: https://www.cloudynights.com/topic/944682-k-corona-from-today-2024-11-16-looking-for-confirmation/ and https://www.cloudynights.com/topic/945270-k-corona-confirmed-on-reanalysis/

This is how the new #coronagraph CCOR-1 on the weather satellite GOES-19 sees the solar corona: https://www.nesdis.noaa.gov/news/noaa-shares-imagery-worlds-first-operational-space-based-coronagraph - the first ever coronagraph designed for "operations" (versus "science").

NASA and SpaceX now are targeting Tuesday, June 25, for the launch of #GOES-U, the fourth and final satellite in the Geostationary Operational Environmental Satellites (GOES) – R Series: https://www.nesdis.noaa.gov/news/nasa-spacex-target-new-launch-date-noaa-weather-satellite and https://blogs.nasa.gov/goes/. On board is the Compact #Coronagraph-1 (CCOR-1): details in https://ntrs.nasa.gov/api/citations/20230004075/downloads/CCOR_EGUPoster2023.pdf and https://www.goes-r.gov/spacesegment/CCOR.html. Differences from the #LASCO coronagraph on SOHO: https://twitter.com/NOAASatellites/status/1772729162358284734 and https://twitter.com/SungrazerComets/status/1772769416846950655.

On #Webb a new #NIRCam capability that allows for simultaneous #coronagraph imaging in both the short and long wavelength channels is now available to the scientific community: https://www.stsci.edu/contents/news/jwst/2023/new-nircam-capability-is-now-available - this new mode was commissioned in June 2023 and shows overall excellent performance, both in collecting the data and in the end-to-end pipeline products.

I've been following this #ESA mission since 14 (!) years when 'around 2012' was the projected launch date (see https://skyweek.wordpress.com/2009/07/08/zwei-esa-satellitchen-sollen-ultimativen-koronographen-bilden for what I wrote in 2009) ... and now the two spacecraft making up the #Proba3 mission are actually finished and should launch in 2024: https://www.esa.int/Enabling_Support/Space_Engineering_Technology/Proba_Missions/Proba-3_complete_Formation-flying_satellites_fully_integrated - they'll fly in formation forming a huge solar #coronagraph with one being the occulter and the other observing the #corona of the #Sun.

As predicted #comet 96P/#Machholz is now in the field of view of #SOHO's #coronagraph #LASCO C3 - which updates https://soho.nascom.nasa.gov/data/realtime/c3/1024/latest.html only intermittendly.
