All of the numbered sunspots in this SOHO white light image have relatively uncomplicated beta-class magnetic fields. Sunspots 9338 and 9345, which are rapidly growing, might soon develop complicated field geometries that would harbor energy for powerful solar flares.

Subscribe to Space Weather News! FAST-GROWING SUNSPOTS: Solar activity has been remarkably low for the past three days, but that could change with the rapid emergence of a new sunspot complex. Active regions 9345 and 9338, which were nearly invisible just two days ago, are now among the largest spots on the solar disk. Rapidly changing magnetic fields above these active regions pose a threat for solar flares.  Above: This 48-hour animation of SOHO white light images shows the meteoric growth of sunspots 9345 and 9338 on Jan. 8th and 9th. ASTEROID FLYBY: Near-Earth asteroid 2001 WO148 will fly by our planet February 15th at 15:28 GMT. At closest approach the 400-meter wide space rock will be 65 lunar distances from Earth -- there is no threat of a collision.

 | On January 19th the University of Arizona Spacewatch program spotted a new Earth-approaching asteroid, 2001 BK41. The ~3 km-wide space rock, which follows a 2.8 year orbit stretching from the inner solar system (between Earth and Venus) to the asteroid belt, poses no immediate threat. Our next close encounter with 2001 BK41 will take place in 2094 when it passes 8 lunar distances from Earth. If current orbital calculations are correct, the asteroid can never come closer than 6 lunar distances from our planet.
