SkyLumi is a free astronomy app published by Kiruna Labs. The library includes observing guides, explanations and stories about the sky. Some guides connect to app stories; others stand on their own. We do not present the library as a peer-reviewed research journal.
Sources before certainty
Science claims are checked against the linked mission, observatory, scientific-organization or research sources. We prefer original sources over reposts. Distances, ages and predicted meteor activity are rounded or qualified when precision would be misleading. A forecast is not a guarantee of clear skies or a specific number of meteors.
What a photograph actually shows
Image captions distinguish observational photographs, wavelength-mapped composites and artist’s impressions. Credits name the people and institutions responsible, link to the original and preserve the applicable reuse terms. Web-sized reproductions may be resized or compressed. A photograph’s colors and detail are not a promise of the naked-eye view. Credited institutions do not endorse SkyLumi.
Authorship and AI assistance
The September 2026 guide collection was researched and drafted with AI assistance for SkyLumi, using the sources listed on each page. We do not invent expert bylines, personal observing experiences or claims of independent astronomer review. Kiruna Labs is responsible for the site’s publication and corrections. Automation can assist drafting and checks; it does not make a claim true merely by repeating it.
Dates and corrections
Publication and update dates describe editorial changes, not each deployment. Dated observing guides retain their year. A later season requires rechecking its calendar, moonlight and geometry. If a statement or credit needs correction, email hello@skylumi.app with the page address and supporting source.
Product claims
The app works on iPhone, Android and in a browser. The core sky works offline; live satellites and high-resolution imagery need a connection. Articles about events do not imply the app predicts individual meteors, sends alerts or has an eclipse-planning feature. We label practical limits where they matter.
