What to include in a calculation report
Include the page URL, latitude and longitude, the eclipse date, and the value that looks wrong. If you are comparing Eclipse Wayfinder with another source, include that source too. Useful examples include a contact time, eclipse type, obscuration, totality duration, Sun altitude or path-margin result.
What to include in a location correction
Tell us which city or country page needs attention and identify the exact statement. Location guides separate stable eclipse geometry from changeable travel details, so please include a current official source when the correction concerns access rules, transport or another time-sensitive fact.
Safety and source corrections
If the issue concerns solar-viewing safety, provide the page and the relevant current guidance. Eclipse Wayfinder uses NASA and the American Astronomical Society as primary public safety references. You can review NASA eclipse safety guidance before reporting a discrepancy.

Before sending a general question
The methodology explains calculations and score weights. The data-sources page lists the astronomy, climate and geographic references. The safety guide explains when solar viewers are required. Those pages may answer a technical question immediately.
