The solar flare occurred on January 20

It was assessed as moderately severe by NASA.

Radio communications may be harmed by solar flares.

WHY IN NEWS

Electrically charged gases mark the Sun's surface, which continue to generate enormous magnetic forces. Magnetic fields are the region of impact that they have. Because these gases are dynamic, the magnetic fields are constantly stretched and twisted. This tangling of magnetic fields can sometimes result in solar flares, which are abrupt bursts of energy. Because these flares can have Earth-like consequences, such as radio blackouts, scientists keep a close eye on them. NASA's Solar Dynamics Observatory has now recorded the Sun generating a mid-level solar flare and published a photograph of the spectacular occurrence on its Instagram page.

It was classed by NASA as an M5.5 class flare, which means it was moderately severe. According to the NOAA, the solar flare occurred on January 20 and peaked at 1:01 a.m. EST (11:31am IST). Solar flares may disrupt radio communications, electric power networks, and navigation signals, as well as endangering spacecraft and astronauts. They frequently take occur in active zones, which are characterised by high magnetic fields. These magnetic fields can reach a threshold of instability and release energy in a variety of ways, including electromagnetic radiation, which is seen as solar flares. In active locations, solar flares are common, but not always, accompanied by coronal mass ejections.

NASA's Solar Dynamics Observatory keeps an eye on the Sun with a fleet of spacecraft that research the Sun, its atmosphere, and the particles and magnetic fields in space around Earth. Last month, NASA issued a warning about spinning Sun debris caused by a solar storm colliding with the Earth, which might cause an aurora (a natural light display in the sky). There was also a chance that radio and GPS systems may be slightly disrupted. However, nothing noteworthy was reported at the time. Solar storms are a common occurrence that occur at regular periods. The length of time it takes for a solar storm to reach Earth is determined by its strength. They can fly at breakneck speeds and arrive 15–18 hours after ejection on Earth.
