FAST WARNING 'PRESTO' MESSAGE from the SIDC (RWC-Belgium) 2024 May 12
14:25:06

A partial halo coronal mass ejection (CME) was observed in SOHO/LASCO-C2
images around 02:00 UTC on May 12. This is possibly associated with a
filament eruption on the SE quadrant of the Sun. It has a speed of about
600 km/s. A glancing blow, associated with this CME, can be expected at the
Earth late on May 14 or early on May 15.

The 3 telescopes of the Extreme Ultraviolet Imager (EUI) onboard Solar Orbiter opened their doors on May 12, 2020 to photograph the Sun. This is exactly 1 year ago. This ‘First Light’ was a crucial step to get the EUI telescopes up and running and pave the path to research.

Kees de Jager 100!

In honour of the 100th Birthday of Kees de Jager, prominent Dutch astronomer and one of our favorite solar physicists, the EUI instrument onboard Solar Orbiter took a pair of images in two different wavelengths. The images were taken in the very early morning of April 29, at 00:19:21 and 00:20:21 CEST representing the years 1921 and 2021.

Solar cycle minimum passed in December 2019

In January 2020, the 13-month smoothed sunspot number rose for the first time since the maximum of cycle 24 (April 2014). Most probably, this indicates that the minimum between cycles 24 and 25 was passed in December 2019.
