The Cosmos at a Glance
- Solar diameter: 1.4 M km
- Earth–Moon distance: 384,400 km
- Hottest flare plasma: 10 M K
- Fastest CME speed: 3,000 km/s
The Sun
A dynamic sphere of plasma photographed by NASA’s SDO every 12 seconds in 12 wavelengths — from the 5,000 K surface to 10‑million-degree flare plasma. Each wavelength reveals a hidden layer of solar activity.
The Moon
Completing a cycle every 29.53 days. Lumara uses Jean Meeus’s Astronomical Algorithms — the same methods used by professional observatories — to calculate phase, illumination, rise/set, and distance offline.
Space Weather
Solar flares are rated B → C → M → X. Coronal mass ejections reach up to 3,000 km/s. Geomagnetic storms are on the G1–G5 scale. Lumara tracks all three in real‑time from NASA’s DONKI database.
Take Lumara With You
Everything you see here — plus offline moon data, solar timelapse videos, and 4K zoom — in your pocket.
- ☼ 12 Solar Wavelengths
- 🌙 Offline Moon Phases
- ⚡ Space Weather Alerts
- 🔒 Zero Tracking
Privacy First
No accounts. No tracking. No ads. Free forever.
Your location stays on your device. Solar and lunar images are fetched directly from NASA servers — we never see your data. Zero data collection. Period.
Mission Briefing
Is Lumara free?
Completely. No premium tier, no ads, no in‑app purchases. Every feature, forever.
Is Lumara on iPhone / iPad?
Coming soon. The iOS build (universal — iPhone + iPad) was submitted to Apple Review on 2026‑04‑27. Add yourself to the waitlist by following @BeeswaxPat for the launch. Android is live now.
Does it track my location?
Never. You pick a city from a list — stored only on your device. No GPS, no transmission.
Where do the solar images come from?
Directly from NASA’s Solar Dynamics Observatory and ESA/NASA SOHO. Updated every ~15 minutes. Public domain.
How accurate are the moon phases?
Jean Meeus’s Astronomical Algorithms — the same methods used by professional observatories. Accurate to minutes.
What are solar wavelengths?
Different wavelengths reveal different layers of the Sun — from the 5,000 K surface to 10‑million-degree flare plasma. 12 views, one star.
What is a coronal mass ejection?
A massive burst of solar plasma traveling up to 3,000 km/s. Can trigger aurora and geomagnetic storms. Lumara tracks them via NASA DONKI.
Do I need internet?
Moon calculations work offline. Solar imagery and space weather require a connection — they’re fetched live from NASA.
What is the Kp index?
Geomagnetic activity on a 0–9 scale. Kp 5+ means a storm (G1–G5) and possible aurora at your latitude.
Who builds Lumara?
