USA: NASA's Solar Dynamics Observatory has detected that a Large Sunspot known as AR3234 has quadrupled in size (SDO). For the next few days, the sunspot is expected to face Earth, and today there is a chance that it may release strong solar flares. So far six different solar flares have been reported from the same sunspot.

On average, the Sun has one solar cycle every 11 years. The number of sunspots is said to increase as the Sun approaches solar maximum.

On the other hand, the quantity drops as the Sun approaches the solar minimum. The recent radio blackout on Earth was brought on by a solar flare emanating from sunspot AR 3217.

Large explosions on the Sun known as solar flares release energy, light and fast-moving particles into space. Flares are broadly classified as A, B, C, M and X and range in intensity.

From 1 to 9, each class is further divided. The energy in each of these squares has increased tenfold. While X-class solar flares are the strongest, C-class and smaller ones are considered less significant events.

According to a new update from Spaceweather.com, the active sunspot AR3234 is rapidly expanding as well as turning toward Earth. "AR3234 has a magnetic field of 'Delta-class' that contains the energy for powerful solar flares."

According to the National Oceanic and Atmospheric Administration (NOAA), there is a 60% chance that M-class solar flares will be visible today and a 20% chance that X-class flares will be observed.

According to NASA, solar flares do not directly harm people because Earth's atmosphere absorbs the majority of the Sun's powerful radiation. Outside Earth's atmosphere, the radiation from the flare can be dangerous to astronauts.

Strong solar flares that are rated M5 or higher have the potential to interfere with GPS and high-frequency radio communications.

Active regions of the Sun, where the magnetic field is particularly strong, are the sources of solar flare eruptions. The internal motion of the Sun, which distorts its magnetic field, creates active regions.

Eventually, the tension in these magnetic fields builds up, and they reconnect. Energy transfers result in solar flares and other types of solar explosions, such as coronal mass ejections.
