This month's featured ADS-B feeder is Sergio Mazzi, a geographer, amateur astronomer, aviation enthusiast, and one of our ADS-B feeders in São Paulo City, Brazil. Since 2017, he has led BRAMON (Brazilian Meteor Observation Network), one of the largest meteor observation networks in the southern hemisphere and Latin America.  

Despite living in a Metropole, one of his favorite hobbies is to observe the cosmos through his telescope. It can be difficult to find dark skies and stars in the skies of São Paulo, but despite this, Sergio is passionate about astronomy and observation techniques. According to the Bortle scale, São Paulo's light pollution is between 8 and 9.

What's light pollution?

Light pollution is the presence of any excessive artificial light. It is most common in large cities where it’s produced by streetlights, billboards, shopping malls, and exterior lights on buildings. Astronomers often use the Bortle scale to measure the night sky’s brightness. This scale ranges from Class 1 (perfectly dark sky) to Class 9 (most light-polluted city sky).
