Evening Wrap: CME Delivers G2 Storm The long-awaited CME from the July 30 long-duration M1.9 flare finally arrived today and stirred things up. Solar activity stayed low overall. The Sun produced only C-class flares, the strongest a C6.3 near the northwest limb. Region 4498 remained the most complex feature on the disk with some growth earlier, while other regions showed little change. No new Earth-directed CMEs appeared in the imagery. A mild shock hit around 11:30 UTC. Solar wind speed rose from the low 300s into the 400–420 km/s range, density climbed, and the interplanetary magnetic field strengthened to around 13–16 nT. That was enough to drive the geomagnetic field from quiet conditi...

🌞 Daily Solar Activity Update – April 28, 2026 🌞 ☀️ SOLAR ACTIVITY LOW AND STEADY The old active regions have fully rotated off the western limb, leaving the disk dominated by a handful of newly emerged sunspot groups on the eastern side. These newcomers are magnetically simple so far, producing only a few weak C-class flares. The 10.7 cm radio flux sits at 112 sfu with flare probabilities staying modest (35% R1, <10% R2). 🌍 GEOMAGNETIC FIELD QUIET Solar wind is running slow at ~340 km/s and the IMF remains mostly northward. Kp is holding steady in the 1–2 range, so geomagnetic conditions are globally calm with no aurora potential and strong HF radio propagation. 🚨 Short-Term Outlook...

🌞 Daily Solar Activity Update – April 27, 2026 🌞 ☀️ SOLAR ACTIVITY EASING OFF Region 4419 and companions are now nearing the western limb and producing mostly C-class flares with one modest M1.2 overnight. The 10.7 cm radio flux has dipped to 129 sfu and flare probabilities are trending downward (50% R1–R2, 15% R3). The disk is starting to look calmer as the active zones rotate out of prime view. 🌍 GEOMAGNETIC FIELD BACK TO QUIET The G1 disturbance from yesterday’s glancing CMEs has faded. Solar wind is down to 410 km/s with a mostly neutral IMF. Kp has settled into the 1–3 range worldwide, ending any aurora activity and restoring excellent HF radio conditions. 🚨 Short-Term Outlook Qu...

🌞 Daily Solar Activity Update – April 24, 2026 🌞 ☀️ SOLAR ACTIVITY JUMPS WITH MAJOR X-CLASS FLARE The Sun just delivered an X2.5 flare (R3-Strong radio blackout) at 0813 UTC from active Region 4419 near the northwest limb. The 10.7 cm radio flux has climbed to 128 sfu, and flare probabilities are now elevated at 55–60% for R1–R2 events over the next three days. This is the strongest flare in weeks and marks a clear uptick from the recent quiet stretch. 🌍 GEOMAGNETIC FIELD QUIET BUT RADIO IMPACTS UNDERWAY Solar wind is calm at 377 km/s with a modest IMF (Bt 5 nT, Bz +3 nT). Kp is holding in the 2–4 range, so no geomagnetic storms are happening right now and aurora chances remain low. How...

🌞 Daily Solar Activity Update – April 22, 2026 🌞 ☀️ SOLAR ACTIVITY REMAINING LOW The Sun is holding steady in quiet mode with only a handful of small C-class flares in the past 24 hours. The 10.7 cm radio flux is at 104 sfu and flare probabilities are low across the board. New sunspot regions are now rotating onto the visible disk from the eastern limb — still simple and magnetically calm for the moment. 🌍 GEOMAGNETIC FIELD FULLY QUIET Solar wind has settled back to ~360 km/s with a neutral IMF. Kp remains in the 1–2 range, delivering perfectly stable conditions worldwide. No geomagnetic activity, no aurora displays, and HF radio propagation is excellent. 🚨 Short-Term Outlook Quiet (G...

🌞 Daily Solar Activity Update – April 21, 2026 🌞 ☀️ SOLAR ACTIVITY LOW AND STEADY The Sun is in a quiet phase with no significant flares reported in the past 24 hours. The 10.7 cm radio flux holds at 105 sfu and flare probabilities remain low (10% chance of R1–R2, 1% for stronger). A few small, simple sunspot regions are on the disk, but none are magnetically complex enough to drive major action right now. 🌍 GEOMAGNETIC FIELD QUIET AFTER LINGERING G1 The coronal-hole high-speed stream has mostly passed, though it delivered G1 (Minor) geomagnetic storming overnight into early today. Solar wind speed is currently around 540 km/s with a modest IMF (Bt ~5 nT, Bz mildly southward). Conditio...

🌞 Daily Solar Activity Update – April 12, 2026 🌞 ☀️ QUIET SUN WITH A TOUCH OF COMPLEXITY Solar activity remains low-key after yesterday’s modest flares. Sunspot number is holding near 55, and a few regions on the visible disk are showing beta-gamma magnetic complexity — enough to keep C-class flares popping but nothing stronger in the past 24 hours. The X-ray background is flat and stable. 🌍 G1 MINOR STORM DELIVERED, NOW FADING FAST The coronal-hole high-speed stream pushed Kp to 4–5 overnight, producing faint but visible aurora at high latitudes. Solar wind has already slowed to ~460 km/s with a mostly neutral IMF. Conditions are settling back to quiet levels and HF radio propagation is...

🌞 Daily Solar Activity Update – April 6, 2026 🌞 ☀️ SOLAR ACTIVITY QUIETS AFTER M-CLASS BURST Sunspot Number sits at 112. AR4409 and several smaller regions remain visible on the disk, but the fireworks have calmed — only low-level C-class flares in the past 24 hours after the M1+ events earlier this week. Flare probabilities: C-class 95% | M-class 45% | X-class 10%. 🌍 QUIET GEOMAGNETIC CONDITIONS Solar wind speed is holding near 540 km/s with a modest, mostly neutral IMF (Bt ~4 nT). Kp is steady around 2, keeping the magnetosphere settled with no storms or aurora displays in progress. 🚨 Short-Term Outlook Geomagnetic activity remains quiet (G0, Kp 1–3) through April 8. No Earth-direc...

🌞 Daily Solar Activity Update – April 5, 2026 🌞 ☀️ M-CLASS ACTION FROM AR4409 Active Region 4409 unleashed a barrage of flares yesterday — 24 events in 24 hours, including an M1.7, M1.3, and M1.0. These triggered brief R1 (minor) radio blackouts over sunlit hemispheres. The region remains complex and productive, with current X-ray flux holding in the B-range but flare probabilities staying elevated. 🌍 ELEVATED SOLAR WIND, QUIET GEOMAGNETICS Solar wind speed sits at 540 km/s with Bt around 4 nT and neutral Bz. The geomagnetic field has settled into quiet-to-unsettled conditions after the recent G1 influence — no storms underway and the Kp index staying low. Minor HF radio degradation possi...

🌞 Daily Solar Activity Update – April 4, 2026 🌞 🌍 SUNGRAZING COMET PERIHELION SpaceWeather.com is highlighting Sungrazing Comet MAPS (C/2026 A1) making its ultra-close pass today. The comet will skim just 160,000 km (0.23 solar radii) above the Sun’s surface — deep inside the solar atmosphere. Odds strongly favor it not surviving the extreme heat and tidal forces, but its final moments should deliver stunning views in coronagraph imagery. ☀️ Quiet Sun, Steady Sunspots No significant flares or CMEs in the past 24 hours. The active regions that rotated into view earlier this week continue to evolve slowly without producing strong activity. The solar disk remains mostly calm in this solar-...
