Daily Space Weather Update: July 30, 2025
🌞 Solar Activity Snapshot:

Sunspot number: 112 (all stable and quiet – no big flares expected today).

Recent solar flares: Max C4 class in the last 24 hours; probabilities for M-class (30%) and X-class (5%) flares remain low.

Solar radio flux: 152 sfu.

🧲 Geomagnetic Conditions:

Solar wind speed: ~463 km/s (moderate).
Planetary K-index: 2.00 (quiet for now).

Storm chances: Up to 40% for severe geomagnetic storms at high latitudes in the next 48 hours – keep an eye out for auroras!

πŸš€ Other Highlights:

No major CMEs or radiation storms reported.

Cosmic rays are at very low levels (-8% of Space Age average) due to rising solar activity in Cycle 25.

Bonus: Noctilucent clouds spotted recently in Europe, and a massive interstellar comet (3I/ATLAS) is making headlines!

Daily Solar Activity Update - July 31, 2025 β˜€οΈπŸŒŒ

Good morning, space enthusiasts! Here's your quick rundown on today's solar weather straight from the experts. Solar activity remains low, but let's dive into the details:

Sunspots: Currently 9 sunspots visible, with a total sunspot number of 131. All are stable and quiet – no major fireworks expected today.

Solar Flares: The past 24 hours saw minor C-class flares (max C2 at 1944 UT yesterday). NOAA predicts a 30% chance of M-class flares and just 5% for X-class in the next day.

Geomagnetic Activity: Quiet conditions with Kp index at 2.33. Low storm probabilities: 10% minor at mid-latitudes, up to 45% severe at high latitudes in the next 24 hours.

Aurora Forecast: No major aurora displays anticipated, but check the auroral oval if you're in northern/southern regions for any subtle glows.

Radiation & Radio: Cosmic rays are declining (-7.9% of average), and no significant radiation storms or radio blackouts reported.

Notable Events: No Earth-facing coronal holes or CMEs. Keep an eye on upcoming asteroid close approaches (like 2025 OD1 today at 9.8 LD – safe distance!) and the potential nova explosion in T Coronae Borealis later this year.

Good morning, space enthusiasts! Here's your quick rundown on today's solar weather:

Sunspots: Current count is 132, with active region 4167 growing and featuring a 'beta-gamma' magnetic field – watch out for potential M-class flares!

Solar Flares: An M3 flare erupted at 1357 UT yesterday. NOAA predicts a 35% chance of more M-class flares and 5% for X-class in the next day or two.

Geomagnetic Activity: Quiet conditions with Kp index at 1.67. Low chances of storms (10% active at mid-latitudes), so auroras might be faint but possible at high latitudes.

Solar Wind: Steady at 430 km/s with low density (2.67 protons/cmΒ³). No major CMEs heading our way.

Bonus Sky Event: Catch Titan's shadow transiting Saturn tonight (06:25-11:04 UTC) if you have a telescope!
