Sunspot Region Produces Mid-Level Solar Flare Pooja Patel

Where/When/How The Event Occurred

On April 17, 2016, the sun emitted a mid-level solar flare from an area on the sun which had a large sunspot on it for the past several days. The solar flare peaked at 8:29 PM EDT. The solar flare occurred because the sunspot is an area of complex magnetivity and that can lead to solar eruptions sending light and radiation off into space.

The dark spot on the sun is what a sunspot looks like.

Effects the Event Has On the World

The harmful radiation emitted from a solar flare cannot pass through Earth's atmosphere. Therefore, this solar flare nor any others can physically harm humans on the ground. If the radiation is intense enough, then it can disturb the layer in Earth's atmosphere where GPS and communications signals travel.

This is what a mid-level solar flare looks like.

The sunspot was large enough to be visible from the ground without magnification. On April 18, 2016, the sunspot was large enough that five earths could fit inside of it.

Trio of Mid-Level Solar Flares

On July 22-23, 2016, the sun emitted a trio of mid-level solar flares. The sun was on a low activity period and those flares were the largest ones seen since April. The effects that this event has on the world are similar to the effects of the sunspot region producing a mid-level solar flare.
