sunspot 978

Sunspot 978 continues to grow: movie. It now covers an expanse of Sun about as wide as the planet Jupiter, making it a fine target for backyard solar telescopes (Palmer used a Coronado SolarMax90). It has also developed a "beta-gamma" magnetic field that harbors energy for M-class solar flares. Will it erupt? Stay tuned!
