The SIDC news marquee announces the most important Solar and Space Weather events.
FAST WARNING 'PRESTO' MESSAGE from the SIDC (RWC-Belgium) 2024 May 15 09:35:03 An X3.5 flare was registered by GOES-16 as peaked today at 08:37 UTC and is associated with NOAA Active Region (AR) 3664 (Catania sunspot group 86). Although a proton event and a Coronal Mass Ejection (CME) might take place as a result, they are unlikely to be Earth-directed. More X-class flaring activity is expected from this AR, however as it is currently turning behind the solar limb, this activity might get obscured.
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.
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.
