CHANCE OF FLARES: NOAA forecasters estimate a 60% chance of M-class solar flares, and a 5% chance of X-flares today. The probable source would be big sunspot AR1654, which is squarely facing Earth.
AURORAS BY SATELLITE: A solar wind stream hit Earth's magnetic field on Jan. 13th, igniting bright auroras around the Arctic Circle. A US Department of Defense meteorological satellite photographed the luminous tendrils winding past Iceland:

Mark Conner of the Air Force Weather Agency prepared the image using data from a low-light camera onboard the DMSP-18 satellite. It shows not only the auroras, but also the city lights of northern Europe and the glow of gas flares from oil rigs in the North Sea. The auroras were every bit as bright as the manmade lights below.
More auroras are in the offing. NOAA forecasters estimate a 15% chance of polar geomagnetic activity as the solar wind continues to blow. www.spaceweather.com
