Sun enters Solar Minimum, when fewer sunspots appear on the star, marking the end of a solar cycle. Every 11 years, the Sun enters on a new solar cycle. Scientists believe the phenomenon is controlled by the Sun’s magnetic field. The Sun’s magnetic field goes through a periodic cycle.In which the south and north poles switch spots. It takes another 11 years for them to switch back.

What happens in solar minimum

During solar minimum, the effects of Earth’s upper atmosphere on satellites in low Earth orbit changes too. Normally Earth’s upper atmosphere is heated and puffed up by ultraviolet radiation from the sun. Satellites in low Earth orbit experience friction as they skim through the outskirts of our atmosphere. Solar Minimum may cause freezing temperature, earthquakes and drought.

Solar minimum 2020

Space specialists have revealed that the sun has gone into the ‘Solar Minimum’ state and is going to enter the deepest period of sunshine recession. According to the reports, sunspots are not noticeable at all and it has nearly been 100 days of 2020 when the sun has indicated zero sunspots.

According to the Astronomer, Dr. Tony Phyllips, Solar minimum is in progress and it’s a deep one. He likewise included that the sun’s attractive field has gotten weak and has been permitting extra cosmic rays into the close planetary system.


In 2017, National Aeronautics and Space Administration (NASA) had anticipated that the sun is entering the solar minimum as the sunspots includes were moderately higher in 2014 and now they have been sliding toward a depressed spot expected in 2019-20.

The government agency has not declared that the solar minimum is here only Dr Phillips said that but his prediction was for it to begin within six months of April 2020, and so it’s reasonable to believe that it has.

Here’s what NASA has to say about ‘solar minimum’ and its impact on Earth

  • In recent article, NASA explained the solar cycle and what effects it can have on the Earth
  • Solar cycle cannot be the main force driving the changes in Earth’s climate.
  • NASA’s forecast for the next solar cycle (25) reveals it will be the weakest of the last 200 years.

Why is It trending?

In all seriousness, lot of us are exhausted, and the possibility of the sun entering a lockdown, or downturn, or whatever other startling expressions some are utilizing makes it eye-finding while looking over a PC, tablet, or cell phone.

Experts say, until NASA or NOAA panics, you shouldn’t either, even if the sun is is winding down its latest solar cycle.
