🌞 Daily Solar Activity Update - September 14, 2025 🌌
The Sun is buzzing with activity! Here's today's space weather report from SpaceWeather.com:
🔥 Solar Flares: No significant flares reported in the last 24 hours, but Active Region 4216 is showing potential for M-class flares. Keep an eye on this sunspot!
🌬️ Solar Wind: Speed at ~374.8 km/s with a density of 3.79 protons/cm³, indicating a calm solar wind environment.
☀️ Sunspots: Sunspot number is 92, reflecting moderate activity as Solar Cycle 25 nears its peak.
🌌 Geomagnetic Activity: A G1-Minor Geomagnetic Storm Watch is in effect today due to a coronal hole high-speed stream and a possible glancing CME impact. Expect minor power grid fluctuations and potential auroras in high-latitude regions like northern Michigan and Maine!
🌠 Cosmic Rays: Neutron counts are down 6.3% from the Space Age average, consistent with the solar maximum reducing cosmic ray influx.

Daily Solar Activity Update - January 15, 2026
Good morning, space enthusiasts! Here’s your quick rundown on today’s space weather from SpaceWeather.com:
Solar Cycle Status: Solar Cycle 25 is nearing its peak, leading to heightened activity. This is evident in reduced cosmic ray levels entering Earth’s atmosphere, with neutron counts reflecting the intensified solar output. 2 6
Sunspot Activity: An active sunspot emerged earlier this week (noted on Jan 12), large and potentially explosive, rotating into view over the sun’s southeastern limb. This could boost solar flares in the coming days. 3
CME Impact and Geomagnetic Storms: A coronal mass ejection (CME) has just struck Earth today, sparking G1 to G2-class geomagnetic storms. This unexpected hit could disrupt radio signals and power grids mildly, but it’s great news for aurora hunters! 10
Aurora Forecast: With the ongoing storms, expect possible auroral displays at high latitudes tonight. Sky watchers in northern regions, keep an eye out!

Good morning, space enthusiasts! Here’s your quick rundown on today’s solar activity from SpaceWeather.com and NOAA data. Solar Cycle 25 is approaching its maximum, leading to heightened activity and fewer cosmic rays bombarding Earth.
Sunspots and Flares: There are currently 9 active sunspot regions on the Sun’s disk. Solar activity remains low overall, but there’s a chance for M-class solar flares today, which could cause minor radio blackouts.
Geomagnetic Conditions: The solar wind storm that started yesterday continues, with winds blowing at nearly 700 km/s (1.6 million mph). This is pressing on Earth’s magnetosphere, potentially sparking G1-G2 (minor to moderate) geomagnetic storms. High-latitude skywatchers: Be alert for auroras tonight!
Aurora Forecast: Possible displays at polar regions due to ongoing disturbances. Kp index could reach 5-6.
Other Notes: Several near-Earth asteroids are passing safely today, including 2025 BL at 4.7 Lunar Distances and 2018 SB2 at 16.2 LD. No threats, but fun to track!

Solar Radio Flux (10.7 cm): 159 sfu
Current conditions are mostly quiet, with only minor potential for HF radio degradation on the sunlit side and brief navigation signal issues. 19
However, a highly volatile sunspot region is rotating into Earth-facing view after producing M-class flares in recent days. This could lead to increased solar flares and possible geomagnetic activity soon – keep an eye out for auroras! 15
3-Day Forecast (Jan 18-20):
Geomagnetic Storms: None expected.
Radio Blackouts: 55% chance of minor-moderate (R1-R2), 5% chance of strong (R3-R5).

Here’s the latest from spaceweather.com on solar conditions:
Sunspot Number: 162 27
Solar Wind: Speed at 896.5 km/sec with a density of 0.32 protons/cm³ 20 . Earth is currently in a stream from a coronal hole, contributing to these high speeds.
Geomagnetic Storm: The severe (G4-class) storm that sparked on Jan. 19 due to a super-fast CME is now subsiding, but it might not be fully over yet 31 . This could still trigger auroras in high-latitude regions.
Recent Solar Flares: A significant X1.9-class flare occurred on Jan. 18 from sunspot 4341 5 , which produced the CME responsible for the recent storm.
Proton Flux: A category S2 solar proton storm was active on Jan. 19, causing shortwave radio blackouts in the Arctic Circle 35 .
Aurora Forecast: With the ongoing geomagnetic activity, Arctic sky watchers should remain alert for possible auroras, especially if the storm persists 40 .

Hey everyone! Here’s your quick daily scoop on solar activity from SpaceWeather.com 3 :
Solar Wind Conditions: Speed at 684.6 km/sec with a very low density of 0.04 protons/cm³. This suggests we’re in a fast solar wind stream, possibly from a coronal hole, which could stir up some geomagnetic activity.
Recent Solar Flares: An M1-class flare peaked at 0740 UT today. Keep an eye out for potential radio blackouts or other effects!
Recent Highlights: Following the X1.9 flare on Jan 18 from sunspot 4341 7 and the CME impact on Jan 20 that sparked a severe G4 geomagnetic storm with stunning auroras (especially over Europe) 6 , things might still be lively. Aurora hunters in high latitudes – check your skies tonight!

Daily Solar Activity Update - January 23, 2026 🌞⚡
Solar Highlights:
Sunspot count: 206 with 12 active groups. AR4345 has a beta-gamma magnetic field, increasing chances for M-class flares. AR4341 recently unleashed an X2-class flare—more activity expected this weekend!
Solar wind speed: 593.4 km/s, density: 1.03 protons/cm³.
Recent flares: Max C3 (6-hr) and C9 (24-hr). Flare probabilities: 60% for M-class, 15% for X-class today and tomorrow.
Geomagnetic Conditions:
Current Kp index: 4.33 (unsettled), with a 24-hr max of 5.33 (minor storm). Earth is in a solar wind stream from a coronal hole.
Storm chances (mid-latitudes): 35% active, 10% minor today; dropping slightly tomorrow.
High latitudes: Up to 45% severe storm potential—prime for auroras!
Aurora Forecast:
Enhanced activity possible at high latitudes. Recent severe storm (Kp=7.6 on Jan 19) sparked unusual auroras in the South Atlantic Anomaly, including purple bands in Brazil. Keep an eye on the oval!
Solar Cycle 25 is nearing its peak, with cosmic rays down 15% from average. Stay tuned for potential flares and storms! 🚀
