Solar Observing Guide in Portuguese

Thanks to observer and volunteer, Alexandre Amorim from Brazil, we now have available a Portuguese translation of the AAVSO Solar Observing Guide available for download (free-of-charge). This helpful Guide explains how to observe and report sunspot counts in a safe and scientifically useful manner.

For the convenience of our observers, we also have translations of this Guide available in French, German, Italian, and Spanish. If you are interested in translating this or any of the other AAVSO observing manuals into your native language, please contact Sara Beck at AAVSO Headquarters.
