It Was Snowing Outside Today (╥﹏╥) - Blog Posts

Since the weather has been cloudy and rainy for about a month now (not a single night where I could take decent photos), here is a photo of the sun from last summer.

Despite the sun just looking like a bright ball of light at first glance, there are actually quite a lot of things to see on it.

This photo was taken using a specific light filter that enhances the details of the sun's surface. All of those black spots are sunspots, regions of the sun that are colder due to local magnetic fields preventing some of the heat from reaching the surface. The slightly brighter regions visible on the side of the sun are solar plage, zones that are slightly hotter, also due to the local magnetic fields.

Finally, the surface of the sun in the picture looks a bit granular/wrought, that is due to solar granulation, smaller (around 1000 km in width) convection currents (basically bubble of plasma) at the surface. (The resolution isn't great so the granulation is not super clearly visible, unfortunately).
