3.7 Apod
I chose the APOD blog from today. It is a photograph of the sun as it's coming off of what is described as an unusually quiet Solar Minimum. It doesn't look like what photographs of the sun look like, however the summary explains that the color of the surface is being emitted by hydrogen. The prominences coming off the sun are interesting, resembling smoke. Aparentally they usually appear dark because they have a cooler surface than the sun. Usually these prominences will last for a month.
