Magnetic Field Weakening And Polarity Change

More signs of magnetic field weakening and disarray

February 5, 2011 – More evidence of magnetic field disarray in the onslaught of a speedy solar wind stream. This latest image was captured on February 5, 2011 when the solar winds accelerated to 608.1 km/sec conveying a proton density of 3.2 protons/cm3. The spectral pattern appears chaotic and disorganized and shows symmetry disparity.

Solar Wind Will Hit Earth Early February

CORONAL HOLE: A dark croissant-shaped hole has opened up in the sun's atmosphere, and it is spewing a stream of solar wind into space. NASA's Solar Dynamics Observatory took this picture of the vast opening during the early hours of Jan. 30th:

Researchers call this a "coronal hole." Solar rotation is turning the coronal hole toward Earth. The stream of solar wind pouring from it will swing around and hit our planet in early February, possibly sparking polar magnetic storms. High-latitude sky watchers should be alert for auroras between Feb. 2nd and 4th.
