JUPITER AND THE MOON: When the sun goes down tonight, step outside and look up. Jupiter and the gibbous Moon are only 5o apart--tight enough to fit inside the bowl of the Big Dipper. The bright conjunction is easy to see even from light-polluted cities. Take a look!
EMERGING SUNSPOTS: Over the weekend, active sunspots AR1967 and AR1968 rotated off the solar disk. However, the chance of flares has not decreased very much. Three new active regions have popped up to take their place:
The circled sunspots, AR1974 - AR1976, have 'beta-gamma' magnetic fields that harbor energy for medium-sized eruptions. And they are growing. NOAA forecasters estimate a 40% chance of M-class flares and a 5% chance of X-flares on Feb. 10th. Solar flare alerts: text, voice
