Solar Weather brings real-time space weather monitoring to your pocket. Track the planetary Kp-index, forecast magnetic storms, and follow moon phases — all in one beautifully designed app. SOLAR WIND See the solar wind that drives it all — speed, plus the all-important Bz and Bt magnetic field straight from NOAA's DSCOVR satellite, with a 24-hour Bz trend. A southward Bz is the earliest sign that a storm and aurora are building. NOAA STORM SCALES Follow the three official NOAA scales at a glance — geomagnetic storms (G), solar radiation storms (S) and radio blackouts (R) — with a 3-day outlook. Turn on alerts for radiation storms and radio blackouts, too. REAL-TIME KP-INDEX Monitor the current geomagnetic activity level on a clear 0–9 scale with color-coded status. See hourly charts for the last 24 hours and spot trends at a glance. STORM FORECASTS View 24-hour and 27-day geomagnetic forecasts sourced from NOAA. Know when the next magnetic storm is coming before it affects your health, electronics, or aurora visibility. MOON PHASE CALENDAR Browse an interactive monthly calendar showing the moon phase for every day. Tap any date to see the lunar day, illumination percentage, and days until the next full or new moon. SMART NOTIFICATIONS Choose exactly which alerts matter to you: • Magnetosphere excited (Kp 2–3) • Magnetic storm detected (Kp 4+) • Severe storm warning (Kp 7+) • Full moon — 2 days, 1 day, or day-of • New moon — 2 days, 1 day, or day-of EDUCATIONAL ARTICLES Learn what the magnetosphere is, how K-index works, how geomagnetic storms affect health, and why the aurora borealis happens. ASK SIRI Just ask Siri — “Is there a magnetic storm?”, “What's the moon phase?” or “What's the solar activity?” — for an instant answer. The same shortcuts work from Spotlight and the Shortcuts app. WIDGETS & LIVE ACTIVITY Keep the current Kp-index, aurora chance, and moon phase on your Home and Lock Screen. When a magnetic storm is underway, a Live Activity shows live readings on your Lock Screen and in StandBy. FEATURES • Real-time Kp-index with hourly bar charts • 24-hour and 27-day storm forecasts from NOAA • Interactive moon phase calendar • 11 configurable push notification types • Real-time solar wind (speed, Bz, Bt) with a 24-hour trend • Official NOAA G/S/R storm scales with a 3-day outlook • Offline moon calculations — works without internet • Dark theme designed for space weather • Available in 17 languages • Ask Siri & Spotlight — storms, moon phase, solar activity • Home Screen & Lock Screen widgets, plus a storm Live Activity • Apple Watch app • Optimized for iPhone and iPad • Built-in knowledge hub with an illustrated glossary • No ads.
