X1.1 solar flare after M5.8 storm warning raises CME-space-weather prospect

A moderate M5.8 solar flare from AR 4475 on June 29 prompted an S1 solar radiation storm warning (issued 16:00 UTC, canceled 16:36 UTC) with no CME detected at that time, though Western-limb location kept Earth at risk for energetic particles. Later, an Earth-facing X1.1 flare from AR 4479 near the solar disk center at 20:50 UTC produced a strong radio blackout (R3) and emitted Type II and IV radio bursts, with analysts awaiting coronagraph data to confirm any Earth-directed CME. Space‑weather conditions were quiet for now, but CME activity from later flares could bring unsettled to active conditions on June 30 into July 1, potentially triggering minor geomagnetic activity on approach of any CME.
