We read every message. Use the form below, or write to contato@ahhoh.com.

What to write to us about

  • A mistake in a guide. Tell us the guide, the sentence and what you think is wrong. If you can, send the source. We check it and publish a note on the Corrections page when we change something.
  • A question about a guide or the game. If something in a guide is unclear, or an instrument did not work on your device, tell us which device and browser you used.
  • Classroom use. Teachers and parents are welcome to use the guides and the game. Tell us what you would like to see.

What we cannot do

We cannot give a personal astronomy consultation, identify a photo of an object in the sky, or promise a reply time. For exact times of sunrise, moonrise, eclipses and phases, use the official tables that the guides link at the end.

Before you send

The form asks for your name, your email address, a topic and your message. We use them only to answer you. The Privacy page says exactly what is kept and for how long. Please do not send anything private that you would not want in an email.
