About
Contact
There is no contact form, no ticket system and no support desk. There is one address, read by the person who runs the site.
A plain email is enough. Put the city name in the subject line if you are writing about a pass — it sorts itself out on this end.
What is worth writing about
- A pass that was wrong. Wrong time, wrong direction, or an elevation that does not match what you saw. Include the city, the date and the time zone you are quoting.
- A pass that is missing. If the station clearly crossed your sky and the table does not list it, that is a genuine bug, usually a twilight or horizon edge case.
- A city that is not there. Cities are added with their whole local context, so it helps to say where you watch from and what blocks the horizon there.
- Permission and reuse. Quoting a paragraph with a link is fine. Republishing whole pages, or using the pass tables in an app, needs a written yes first.
- Privacy and advertising. Data requests and anything about the ads on this site.
What you will not get
No observing advice by email, no telescope recommendations and no homework help. Those questions are answered better — and publicly — in the guides and the FAQ, which is also where the answer stays useful for the next reader.
How fast
Usually within a few days. This is a one-person site next to other work, so a correction can take a week if it needs a rebuild and a re-check of the orbital data. Everything that is actually wrong gets fixed; not every suggestion gets built.
