An Aurora Cupcake with a Milky Way Topping
I chose this article because I, personally, find the Aurora light shows amazing and hope to see it in person one day. When reading over the article I found that double auroral ovals were seen over Sweden. The auroral ovals were topped off with the central band of our Milky Way galaxy, making the whole image look like a rainbow cupcake. I learned that auroras are caused by our sun ejecting plasma clouds into the Solar System (in this case, it happened a few days before), thus ending in ionized particles subsequently impacted the magnetosphere of Earth. The article ended off on an active sunspot group, which out of curiosity, I clicked to follow. The page I was redirected to was from August 1, 2002. One that page, reports of sunspot clusters that were about thirty times the diameter of Earth were displayed and I learned that individual sunspots are not cataloged but group clusters of sunspots are.
I chose a different APOD for 1.3, but I was curious as to how the auroras were formed. Thank you!
ReplyDeleteGreat post! I also chose this photograph because I find the lights displayed to be something everyone, including myself, should see. Something I didn't do was click on the sunspot group and learned a lot from what you described reading on the link.
