Nasa reported beginning of solar cycle

During this Solar Cycle, the sun will transform from calm to intense to active seasons.

However, the Sun's activity isn't always catastrophic with the energy it releases creating lovely auroras, bright lights seen in the night sky on Earth.

The panel's second co-chair, Douglas A. of the Space Weather Forecast Center in Boulder, Colo. (Closer to the solar equator is better.) "Since we're seeing these at low latitudes, that is another indicator that we should see a weak cycle", she says.

Scientists have expressed fears that a strong solar storm may hit the Sun. Another area of solar study, called helioseismology, involves scientists collecting soundwaves from inside the Sun, as a way of probing the elusive dynamo. It was also the weakest cycle in 100 years.

As the sun moves towards its new cycle, dramatic events can occur at the bottom - massive explosions such as solar flares or coronal mass emissions. Then it takes about another 11 years for the Sun's north and south poles to flip back again.

"Just because it's a below-average solar cycle, doesn't mean there is no risk of extreme space weather", said Doug Biesecker, a solar physicist.

According to the NASA news release, the experts predict the current solar cycle to be rather similar in strength as the last one, which was considered to be below-average. According to the NOAA meteorological agency, the star entered an 11-year cycle, the 25th in a row, starting in 1749, when astronomers began to keep track of the appearance of sunspots.

A panel of worldwide experts convened by NASA and the National Oceanic and Atmospheric Administration has predicted that this cycle will reach its peak in July of 2025, and the intensity should be nearly identical to the previous cycle-which was not very strong.

New ‘solar cycle’ has begun, Nasa says

During the peak activity of the last solar cycle, 120 sunspots were recorded.

The new cycle began in December 2019, but was not confirmed until now, Upton says, because sunspot numbers are variable.

That's because energy from solar storms makes the Earth's upper atmosphere expand. Researchers monitor all this activity by keeping an eye on the number of sunspots, temporary dark patches on the Sun's surface. The Sun periodically ejects boiling-hot plasma, in the form of solar flares and solar wind, across the Solar System.

We predict the decline in solar cycle amplitude, seen from cycles 21 through 24, has come to an end.

Lika Guhathakurta, photo voltaic scientist on the Heliophysics Division at NASA Headquarters in Washington said that as Earth emerges from photo voltaic minimal and approaches Cycle 25's most, you will need to do not forget that photo voltaic exercise by no means stops. Astronauts can also be harmed. Power grids, satellites, GPS, airlines, rockets and space exploration are all affected by solar flares.

With solar minimum already over, scientists expect the Sun's activity to increase toward the next predicted maximum in July 2021. Scientists are eager for the opportunity the maximum will allow for further study of the Sun.

To determine the start of a new solar cycle, the prediction panel consulted monthly data on sunspots from the World Data Center for the Sunspot Index and Long-term Solar Observations, located at the Royal Observatory of Belgium in Brussels, which tracks sunspots and pinpoints the solar cycle's highs and lows.
