~ Space Weather Update~ INCOMING CME, CHANCE OF STORMS [1]
COLDEST SPOT IN THE KNOWN UNIVERSE: NASA engineers are building a refrigerator for the International Space Station that can make atoms colder than anything else in the known universe. Inside this "Cold Atom Lab [2]," researchers hope to discover new forms of matter and novel quantum phenomena. Get the full story [3] from Science@NASA.
INCOMING CME, CHANCE OF STORMS: Big sunspot AR1967 is crackling with solar flares and hurling CMEs into space. The biggest CME so far was propelled away from the sun on Jan. 30th by an M6-class [4] explosion in the sunspot's magnetic canopy. It is expected to reach Earth on Feb. 2nd:

The blast was not squarely Earth-directed. Instead, it will deliver a glancing blow to our planet's magnetic field. NOAA forecasters estimate a 45% chance of polar geomagnetic storms when the cloud arrives on Sunday. High-latitude sky watchers should be alert for auroras. Aurora alerts: text [6], voice [7]
