The following is the continuation of the articles on Solar flares:

"3. There can be more than 20 solar flares every day at peak periods
The Sun can produce around 100 solar flares each week when it reaches solar maximum. This is the point in its 11-year cycle when solar activity is at its most intense.

Thankfully, most of these are not pointed in Earth's direction.

4. Solar flares are hotter than the Sun's core

The temperature inside a solar flare typically reaches 10 or 20 million degrees Kelvin and can be as high as 100 million degrees Kelvin. In comparison, the Sun's core typically reaches temperatures of about 27 million degrees F (15 million degrees C).

5. They can wreak havoc on electrical systems and gadgets

The Hydro-Quebec power grid in Canada was severely damaged in March 1989 by a massive CME that was among the largest ever recorded. Such events show us just how powerful the Sun, and cosmos in general, can be.

When these coronal mass ejections hit the Earth, they can trigger mild to severe geomagnetic storms that can damage GPS satellites and power infrastructures.

Other examples have occurred in more modern times too. For example. China's radio communications were hampered by a CME that an X-class solar flare, the highest classification, created in February 2011.

According to a National Academy of Sciences research from 2008, a significant solar storm might result in twenty times the economic damage that Hurricane Katrina did.

6. Depending on how quickly they move, they become more or less deadly

Scientists may be able to assess if high-energy particles can cause damage on Earth by measuring their speed during intense solar storms.

According to Joseph Kunches, a scientist at the Space Weather Prediction Center, "generally speaking, if they're slower, they'll deposit all of the energy into your body because they're not fast enough to fly right through,"

7. Predicting them is very tricky

The time it takes for solar flare radiation to reach Earth from the Sun is just over 8 minutes. As a result, we don't have much time to react to these eruptions.

Although it can be difficult to predict space weather, we have gotten better at it over the past few decades.

Powerful flares rarely give us much warning before impacting and can have a substantial impact on spacecraft, satellites, and ground-based systems. NASA, NOAA, and the U.S. Air Force Weather Agency (AFWA) are among the many agencies keeping a careful eye on the Sun and closely monitoring it for strong flares and related magnetic storms. These groups can alert technological industries that are susceptible to solar flare activity so that the proper safety measures can be taken.

"We can't ignore space weather, but we can take appropriate measures to protect ourselves," NASA says.

Solar flares are usually not a cause for concern. There are no so-called "killing flares," and while solar flares can potentially dramatically disrupt technology, they lack the energy to cause long-term harm to Earth.

"Even at their worst, the sun's flares are not physically capable of destroying Earth," NASA says.

8. The current solar activity peak should be around 2025
As we are now in Solar Cycle 25, the 25th cycle to occur since regular record-keeping began with Solar Cycle 1 in 1755. Solar Cycle 24 lasted 11 years, an average length, and had the 4th-smallest intensity since regular record-keeping began with Solar Cycle 1. It was also the weakest cycle in 100 years.

Solar Cycle 25, which began in 2019, is also forecast to be a weak cycle. Solar maximum is expected in July 2025, with a peak of 115 sunspots.

There are various open-source places to monitor the Sun's current activity, like SpaceWeatherLive.

They record the most recent 24 hours of solar X-ray data from the main GOES-16 satellite and display such activity in helpful graphs along with the percentage chance of different types of solar flares, so users can find out if there is a solar flare today and stay up to date with the most recent space weather findings.

9. Superflares are unlikely from our Sun, but not impossible
It may come as a surprise that red dwarf stars, which are typically considerably fainter and cooler than the Sun, can produce flares with substantially higher total energies because of changes in their interior structures. Could our Sun ever produce one too?

"Superflares are produced by stars that have very strong magnetic fields and therefore are associated with more violent activity than our Sun," Stephanie Yardley, a space weather specialist at University College London's Mullard Space Science Laboratory in the U.K., told Live Science.

"However, superflares do happen on stars that are similar to our Sun. Evidence from studying carbon isotopes found in tree rings suggests that superflares may have been produced by our Sun thousands of years ago and so could occur in the future — but these events are extremely rare," he added.

And that, Solar activity addicts, is your lot for today.

Solar flares, and their associated outpouring from the Sun, are dramatic events but are completely natural and nothing to lose sleep over. While large ones have occurred over time, they do not present any serious threat to you physically.

Our electrical grids and electrical equipment, however, cannot say the same! Sometimes it pays to be made of flesh and bone!"

So one day you electronic devices and the power grid may be down due to a flare, but you will be alive and well due to the Earth's protection of life.
