Our characteristically dormant Sun has shown signs of awakening from it’s year plus long slumber this week. Specifically, a new sunspot group has formed on the Earthward facing side, and is now rotating towards the limb. This is definitely part of the new solar cycle #24, as characterized by its reversed polarity. Thus far, this solar cycle has been off to a sputtering start, at best. All amateur scopes, be they hydrogen Alpha, Calcium K, or safely filtered white light are encouraged to watch as this “monster” sunspot rotates around this Sun’s limb. The group already shows the envelopment of a fine dark umbra embedded in a pale penumbra, and will hopefully throw some looping prominences up through the chromosphere as it rotates from view. If you do not have optical means, you can still follow the action via SpaceWeather (the link above) or the Solar Heliocentric Observatories’ (SOHO) website! Enjoy!
