GoKawiil// 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.
