Before we start our citizen science project on sun spots, I wanted to look into what sun spots were and why it was important for my group to study them.
Sun spots are basically spots on the sun that appear darker than their surroundings because they are about 1500K degrees cooler. Sun spots are usually large enough to be seen with the naked eye (but don’t look directly at the sun or you’ll be blinded!). Sun spots develop and persist for various period of time and because the sun rotates, they move around with the sun. The dark center of the sun spot is called the umbra and the lighter region around is called the penumbra. What’s interesting about the sun is that because it is not a solid body, it doesn’t have a defined rotational period and so scientists have to make an estimate about the length of time it takes to rotate.
The number of sun spots present correlate with the amount of solar activity present at the moment. Solar activity (such as solar wind and magnetic storms) have effects on non-thermal radio and x-ray emissions. It is believed that sun spot activity directly effects the Earth’s climate, which is interesting to study as our climate is changing rapidly. I want to discover the relationship between sun spots and our changing climate and how celestial bodies can effect one another.
For our digital deliverable, our group is thinking about creating a documentary on sun spots to educate our peers on climate change and solar activity. We also want to document our experiences traveling upstate and actually interacting with the natural environment that surrounds us.
These are images of a sun spot and a collection of sun spots.
