The solar poles become quadruple this month


The Sun's magnetic polarity is reversed and polar quadrupled this month, meaning by this that positive field’s surface in the north and south poles and negative fields in Ecuador according to the Astronomical Observatory of Japan and other institutes.

When a similar phenomenon occurred about 300 years ago, the temperature of the planet dropped slightly.


A research group led by Saku Tsuneta, a professor at the observatory analyzed data from magnetic fields using the Hinode satellite observation, and confirmed that the polarity of the magnetic fields of the North Pole began to reverse in July last year.

The researchers also found that the magnetic field of the South Pole, which is expected to be reversed along with the North Pole, maintained a positive polarity, ensuring the formation of a quadruple magnetic field.

The reason behind this change in the sun's poles is not yet understood by scientists. Yet we know that this change of polarity coincides with the increase and decrease in the number of sunspot cycles of approximately 11 years.

The current sunspot cycle has spanned nearly 13 years.

A similar situation occurred in the 17th century to the 18th century when the average temperature in the Northern Hemisphere dropped 0.6 ° C. The research group believes that a similar phenomenon occurred quadruple polarity in those years.
