How researchers in Brazil are monitoring the growing magnetic anomaly

Hey National Observatory (ON) He contributed to the data Monitoring of magnetic anomalies in the South Atlantic Ocean (AMAS). The region includes southern and southeastern Brazil.

AMAS has a weaker density than magnetic field Earth, and its westward growth has attracted the attention of scientists. But, according to the foundation, AMAS offers no cause for concern.

• To monitor information, ON has two observatories. One of them, Tatoca, is located on an island in Belém, Pará; The other is called Vasouras, and is located within the city of Rio de Janeiro. ON also has magnetic stations distributed throughout the country.

The Vassouras Observatory, which has been operating continuously since 2015, plays an essential role in creating global models and understanding the origin of AMAS. It complements satellite missions that record the magnetic field.

• The magnetic field acts as a protective shield against cosmic radiation and solar winds that reach the planet. As in the AMAS region, this protection is weaker, and particles can enter more easily.

But this is no cause for concern, according to Fireman, as the main impacts are experienced by satellites. In addition, NASA and the European Space Agency (ESA) are monitoring this anomaly.

According to NASA, analyzing the phenomenon is important for understanding the mechanisms that produce the Earth’s magnetic field, as well as its changes.

As the area has been monitored, even satellites are ready to handle the weaker magnetic field resulting from the anomaly.

“When satellites pass through the AMAS area, they can go into standby mode (standby mode) so as not to suffer any damage. It is like a household appliance: if there is a fluctuation in the electrical power supply, the famous “light” comes on, it is recommended to turn off the device until It doesn’t burn,” says the technician.
