SPACE WEATHER
Sunspot 1026 is about as wide as Earth. SOHO measurements show the spot's
magnetic polarity and identified it as a member of new Solar Cycle 24.
New sunspot cycle begins
SUNSPOT 1026: One sunspot is not enough to end the deepest solar minimum in nearly a century, but you've got to start somewhere. "Finally, a new sunspot!" says Paul Maxson who sends this picture from his observatory in Surprise, Arizona: Sunspot 1026 emerged yesterday to break a string of 19 consecutive spotless days.
It's about as wide as Earth, which makes it an easy target for backyard solar telescopes. The Solar and Heliospheric Observatory (SOHO) has measured the spot's magnetic polarity and identified it as a member of new Solar Cycle 24.
SUNSPOT UPDATE: A second sunspot is emerging to join the one reported below: SOHO image. This is the first time in more than a year that two relatively-large sunspots have shared the Earth-facing side of the sun.
