NASA registrerar rekordlång solradiostörning på 19 dagar

23 maj 2026

Rapporterad av AI

NASA-forskare observerade en solradiostörning som varade i 19 dagar under augusti 2025, vilket vida överstiger det tidigare rekordet på fem dagar. Händelsen följdes med hjälp av flera rymdfarkoster i solsystemet och kopplades till en så kallad helmet streamer på solen.

Den utdragna signalen identifierades som en typ IV-radiostörning, genererad av energirika elektroner som fångats i solens magnetfält. Forskare kombinerade data från NASA:s STEREO, Parker Solar Probe och Wind-uppdrag, tillsammans med ESA:s och NASA:s Solar Orbiter, för att följa störningen allteftersom solen roterade.
