The Sun Online and solar activity. March 18, 2014

NOAA AR 2010 released this morning a C3.4 flare and is still candidate for more C-flaring activity. The global probability for C-flares is well above 50%.The solar wind speed is below 400 km/s, this is a slow solar wind.
A small increase in the magnetic field strength followed by a smooth increase in the solar wind speed this morning can possibly be linked with the northern coronal hole which passed the central meridian on March 13.
The geomagnetic impact is negligible.

NGC 2736
 (also known as the Pencil Nebula) is a small part of the Vela Supernova Remnant, located near the Vela Pulsar in the constellation Vela. The nebula’s linear appearance triggered its popular name. It resides about 815 light-years (250 parsecs) away from our solar system. It is thought to have been formed from part of the shock wave of the larger Vela Supernova Remnant. The Pencil Nebula is moving at roughly 644,000 kilometers per hour (400,000 miles per hour).

Cosmic Microwave Map Swirls Indicate Inflation

Explanation: Did the universe undergo an early epoch of extremely rapid expansion? Such an inflationary epoch has been postulated to explain several puzzling cosmic attributes such as why our universe looks similar in opposite directions. Yesterday, results were released showing an expected signal of unexpected strength, bolstering a prediction of inflation that specific patterns of polarization should exist in cosmic microwave backgroundradiation — light emitted 13.8 billion years ago as the universe first became transparent. Called B-mode polarizations, these early swirling patterns can be directly attributed to squeeze and stretch effects that gravitational radiation has on photon-emitting electrons. The surprising results were discovered in data from the Background Imaging of Cosmic Extragalactic Polarization 2 (BICEP2) microwave observatory near the South Pole.BICEP2 is the building-mounted dish pictured above on the left. Note how the black polarization vectors appear to swirl around the colored temperature peaks on the inset microwave sky map. Although statisticallycompelling, the conclusions will likely remain controversial while confirmation attempts are made with independent observations.
