Subject: Have you ever heard of aurorae autralis taking place in Brazil ?

  The South Atlantic anomaly is an irregularity of the geomagnetic field 
near the brazilian coast. According to the theory, particles from outer 
space interact more profoundly at that region and contribute to create “low 
altitude” aurorae.
 The book “Majestic Lights”, written by Robert H. Eather, brings the 
information that approximately 0,01% of the Rio de Janeiro’s nights has an 
aurora australis ( once in 27 years and some months ).
  However, I have no information about such occurences taking place there. 
I am aware of the problem of light pollution, but what I want to know is if 
there is ( or was ) some kind of researches on that area and what the 
results are.

  Thanks for your attention
