Another huge coronal hole has opened up on
our Sun and is facing Earth and is spewing streams of solar wind towards Earth
at an incredible 750 kilometers per second.
It’s another massive hole in the Sun’s
atmosphere and could influence major quake activity here on Earth in the coming
days.
The whole is so huge it stretches more than
halfway across the face of the Sun.
Spaceweather reports: This is a
"coronal hole" (CH)--a region where the sun's magnetic field opens up
and allows solar wind to escape. NASA's STEREO spacecraft recently sampled the
stream flowing from this hole and the velocity was unusually high: 750 km/s.
Such a fast-moving stream will almost surely spark Arctic auroras when it
arrives on Feb. 1st.
The action could begin even before the
stream arrives. NOAA forecasters say there is a 65% chance of geomagnetic
storms on Jan. 31st when Earth crosses through a fold in the heliospheric
current sheet. Many people have never heard of the heliospheric current sheet,
yet it is one of the biggest things in the solar system--a vast undulating
system of electrical currents shaped like the skirt of a ballerina. Earth dips
in and out of it all the time. These crossings are called "solar sector
boundary crossings," and they can cause high-latitude auroras

This is interesting. Last night Feb 1st, my dog began howling which he never has done before and an air purifier and a radio turned on by themselves, between 2:00 & 3:00 AM.
When I arrived at work a co-worker told me a very similar story of his dog and a radio and intercom system.
Google earth GPS has been way off for several days now.
