This page lists the rules every guide on ahhoh.com follows. If we break one, tell us and we will fix it.

Sources

  • We use official sources: NASA, including the Goddard eclipse site, the U.S. Naval Observatory, NOAA, NIST, ESA, and observatories and universities that name themselves on the page.
  • We do not use blogs, forums, shops or pages that sell products.
  • We open every source ourselves and read it. A source we did not open does not go in a guide.
  • Every guide prints each source with its link and the date we opened it.
  • Every entry is checked against at least two sources.
  • When two sources disagree, the guide says so and says which one we follow and why.

What goes into a guide

  • Every number, date and name comes from a source we opened. We show simple arithmetic when we do it ourselves, and we say it is ours.
  • We do not invent quotes, statistics, experts or reviews, and we do not quote long passages.
  • Dates of future events appear only when they come from an official table with its date.
  • The drawings are our own. They are computed from the numbers in the sources. We use a NASA picture only when the page itself confirms the license, and we credit it.
  • We do not recommend products or brands, and we use no affiliate links.

Eye safety

Where a guide talks about a solar eclipse or about watching the Sun, it carries a fixed warning: never look directly at the Sun without proper eye protection. For the rest, we repeat only the advice of official sources such as NASA, and we do not suggest improvised filters.

Models and the game

The instruments in the game are simplified. For example, orbits are drawn as circles and a match counts inside a window. The game teaches how the cycles work, and it does not predict exact times. Each guide says when it uses a simplification, and the Methodology page lists them.

Tools we use

Our team uses AI writing tools to help draft guides. Every guide is then checked against the sources listed at its end, and the numbers are checked against those sources again before publication. Responsibility for what is published stays with the ahhoh.com team.

Advertising

ahhoh.com has no ads, and nothing in the game rewards clicks, shares or visits. The only rewards are medals, seals and cards inside your own logbook.

Corrections

When we find or receive a mistake, we fix the guide, and we record the change on the Corrections page with the date. See that page for how to report one.
