Read the given passage and answer the questions that follow.

As the Sun inches closer to its peak activity in its solar cycle, an explosion has been picked
up behind the north-eastern 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 31 July 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," space weather, 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 north-eastern limb later this week. A new
sunspot group could bring an end to weeks of relative quiet," space weather said in its report.
