The best way to reach Astrotempo is by email:
What to write about
- Corrections. If a time or value looks wrong, please include the place (or coordinates), the date and what you expected. That makes it possible to check the calculation quickly.
- Questions about the tools, the methods or the results.
- Ideas for new tools or improvements.
- Privacy requests, for example to exercise your rights under the GDPR. See the privacy policy for details.
- Press and collaborations.
I read every message. Astrotempo is a one-person project, so replies can take a few days.
Astrotempo does not offer personal consultations, for example for buying telescopes or planning expeditions. For safety-critical decisions, such as observing the Sun, please follow official guidance.
