Volatile sunspot fires 21 major flares in 24 hours as region turns Earth‑ward
In a 24‑hour period a rapidly growing sunspot produced at least 18 M‑class flares and three X‑class flares — including an intense X8.3 eruption — as the active region rotates into an Earth‑facing position. The concentrated burst elevates near‑term space‑weather monitoring for satellites and HF/GNSS services.
