Thanks to the hard work and perseverance of David Duarte and his colleagues at the Centro de Estudos Astronômico de Alagoas (CEAAL), there is now a version of the AAVSO Manual for Visual Observing of Variable Stars available for download here:

We hope that this manual will be helpful to all of our many Portuguese-speaking observers and that you will feel free to share it with others.
