Solar Minima is here!

The sun is blank, just like my mind most of the time 😂 This one from the “solar observatory” at home a couple of days ago. Solar minimum is here, folks!

Sunspots are areas on the Sun’s photosphere (outer layer) where the temperature has dropped a couple of thousand degrees. That doesn’t mean sunspots are cold, they are still at least 3000°C. This is because the magnetic flux generated at that spot reduces the heat.

They’re actually bright if all alone. Taking away the photosphere will cause the sunspot to outshine the moon. The darkening comes from a phenomenon called black body luminance – something to search about if you’re interested.
