AR1748
En närbild av solfläckgruppen AR1748 (Gruppen till vänster i bild) som de senaste dagarna producerat 4 stycken X-klassade utbrott. I skrivande stund ser jag hur norrskensovalen växer och om det inte vore för de ljusa sommarkvällarna så skulle nog norrskenet synas ute nu.
Uppe till vänster syns ett skalenligt jordklot för att påminna er om hur små vi är jämfört med vår närmaste stjärna, solen. Det är lätt att bli ödmjuk när man tänker att här sitter vi på en rund sten i rymden och är helt beroende av denna så speciella stjärna.

Here's a closeup shot of the active sunspot AR1748 (it's the sunspot group to the left) I took today. It doesn't look like much but it been producing strong solar flares lately and as I'm writing this I can see how the earth is starting to be hit by the solar wind and the auroral oval is growing.
If we didn't have these bright summer nights we would probably see some auroras right now. As you can see I also added color to this image and as I mentioned in another post, this is my personal choice of color on the sun.
Up to the left you can see a scaled sized of the earth, just so you won't forget how small we are compared to our nearest star, the Sun. It's easy feel small and humble that we on this small rocky planet in cold black space, is totally dependent on this special star.
