Although solar activity was at low levels over the past 24 hours, multiple long-duration C-class solar flares, associated with activity from Region 3599 as it rotated beyond the west limb, produced coronal mass ejections (CMEs) that sent proton flux rising to S1 – Minor levels.
Proton flux started rapidly rising at 07:30 UTC on February 12, 2024, following what appears to be an eruption from the old Region 3575 – now traversing the farside of the Sun.
A moderately strong solar flare measuring M6.7 erupted from Active Region 3559 (beta-gamma) at 04:38 UTC on January 29, 2024. The event started at 03:54 and ended at 05:15 UTC.
A full-halo coronal mass ejection (CME) first visible in LASCO C2 imagery at 03:36 UTC on March 13, 2023, produced S1 – Minor Solar Radiation Storm at 07:50 UTC.
A long duration solar flare measuring M2.3 at its peak time erupted from departing Region 2473 at 00:11 UTC on January 2, 2016. The event started at 23:10 UTC on January 1 and ended at 01:01 UTC on January 2. A Type II (estimated velocity 1019 km/s) and a Type IV…
Earth is currently under the influence of S1 (minor) solar radiation storm created as a result of yesterday's M7.3 solar flare. Our planet is showered with highly energetic solar particles (primarily protons) released from the flare site. Extende
This morning at 08:05 UTC, sunspot 1263 produced an X6.9 solar flare, the third X-flare of new Solar Cycle 24 and the most powerful so far. NASA's Solar Dynamics Observatory captured the explosion's extreme ultraviolet flash:The brunt of the ex
