On 18 January 2026, the active region 4341 produced a long-duration X1.9 flare, a fast halo coronal mass ejection (CME) with a projected speed above 2000 km/s, and one of the largest >10 MeV proton enhancements in the GOES record (S4). In SolO/STIX, the flare shows a clear train of quasi-periodic pulsations (QPPs) in the non-thermal hard X-rays, pointing to repeated episodes of electron...

Coronal mass ejections (CMEs) are often accompanied by a variety of solar radio emissions, among which moving type IV bursts are particularly interesting. These complex radio bursts are thought to be produced by energetic electrons trapped within expanding CME magnetic structures. Previous studies indicate that both gyrosynchrotron and plasma emission processes may contribute. Investigations...
