Something exploded behind the Sun. Its intensity remains unknown
As the Sun inches closer to its peak activity in its solar cycle, an explosion has been picked up behind the northeastern limb of the star in our solar system. Solar observatories saw bits and pieces of the explosion, which remain obscured in view from Earth's orbit.
The explosion was spotted on July 31 at around 2309 UT and Earth-orbiting satellites registered a long-lasting C9.3-class solar flare. "The intensity is probably an underestimate because it was partially eclipsed by the edge of the sun. Nasa's Solar Dynamics Observatory (SDO) saw hot debris flying away from the blast site," spaceweather, which tracks the solar activity, reported.
While the explosion was powerful, experts have predicted that Earth is not in the line of fire from the Sun. Scientists are expected to get a view of the active region later this week as it comes to sight.
"Earth is not in the line of fire. The explosion is significant because it may herald an active region set to emerge over the sun's northeastern limb later this week. A new sunspot group could bring an end to weeks of relative quiet," spaceweather said in its report.
Meanwhile, the US-based National Oceanic and Atmospheric Administration (NOAA) has predicted that there is a chance of a minor G-1 class geomagnetic storm hitting Earth. The event is due to an explosion on a southern hole in the sun's atmosphere, which has released a high-speed stream of solar wind and gaseous material toward the inner planets including Earth.
Geomagnetic storms are a major disturbance of Earth's magnetosphere that occurs when there is a very efficient exchange of energy from the solar wind into the space environment surrounding Earth.
