Sun online. Solar activity. 2nd of September 2013

Solar activity has been eruptive during the past 24 hours, featuring one
C1.7 flare from NOAA AR 11834 peaking at 14:20 UT. More C flares from NOAA
AR 11834 and 11836 are likely within the next 48 hours, with a slight
chance for an M flare.Solar wind speed rose from about 460 to 580 km/s
around 6h UT on September 1, possibly due to the effects of the CME of
August 30. Solar wind speeds later decreased to about 430 km/s and climbed
to a peak of 520 km/s around 3h UT on September 2. Current wind speed lies
around 420 km/s. Meanwhile, the Interplanetary Magnetic Field varied
between 2 and 6 nT. Solar wind may experience the influence of a small
Coronal Hole on September 4. The geomagnetic activity was at quiet levels
(K Dourbes between 1 and 3; NOAA Kp between 2 and 3) during the past 24
hours. Quiet conditions (K Dourbes < 4) are expected for September 2 and 3.
Quiet to active conditions are possible on September 4, due to the effects
of a Coronal Hole high speed stream.

Milky Way Over Spain’s Bardenas Reales

Explanation: What’s that below the Milky Way? First, across the top of the above image, lies the faint band that is our planet’s sideways view of the central disk of our home Milky Way Galaxy. The Milky Way band can be seen most clear nights from just about anywhere on Earth with a dark sky. What lies beneath is, by comparison, is a much less common sight. It is the striking peak of Castildetierra, a rock formation located in Bardenas Reales, a natural badlands in northeast Spain. Standing 50 meters tall, the rock spire includes clay and sandstone left over from thousands of years of erosion by wind and water. The astrophotographer waited months for the sky to appear just right — and then took the 14 exposures that compose the above image in a single night.
