lori100: It's shaped like the U.S. ? ...I don't think so....maybe the sun is just having a bad decade...it could happen...maybe it's just age spots....

I think the important point is the large holes in the upper layers types allow solar wind to blow out across the solar system.

And there seems to be holes almost at both poles of the sun. The ' upper layers ' seem to have got thin at the top as well. That leaves only a belt around the middle which is going on as normal.

Astroblog claims that auroras are visible in Tasmania.

The implication is they are a result of the coronal holes.

Although there is a monitoring station, so they can not be such a surprise.

" Powerful Nor’easter to hit US Northeast " earthsky reports.

An effect of the sun coronal hole or the passing asteroid?

Changes in the sun causes changes in the weather on earth.

Earthsky suggests blizzards in New York which is an interesting thought.

Blizzards fail to arrive but the temperature drops in the UK.

“It is incumbent on us to communicate forecast uncertainty,” Uccellini said. “We need to make the uncertainties clear.”
He added: “We’re going to review this [issue of communicating uncertainty in weather forecasts] very carefully and assess a different approach as we deal with these types of storms.”
However, Uccellini stressed erring on the side of caution and planning for the worst was “the right decision” given the potential for “extraordinary” snow totals." Washington post/Mr Computer.

-3 to -11 or lower is forecast in New York this week.

I think I read somewhere that low sunspot activity at this time of year could help cause a Nor’easter.

"Brooklyn, NY -- An unusual interdisciplinary study by astronomers and climatologists has found a striking correlation between holes in the outermost layer of the sun -- or the corona -- and the globally averaged temperature of the Earth, suggesting that the Earth's atmospheric temperature may be strongly linked to solar magnetism changes over months or years..."

"In a paper that appears in the February 28 issue of the journal New Astronomy,..."

"....The scientists compared the Earth's temperature with the size of coronal holes reported on the Sun during a two-decade period, starting in January 1979 and ending April 1998. Results show a clear drop in terrestrial atmospheric temperature after the Sun's magnetic field activity is most intense. At this point, there is a dropping off of magnetic activity and an enlargement of the coronal holes. "This is the first time anyone has combined these modern, reliable data sets to link solar activity and climate, and to cite several alternative mechanisms that might explain this link," Posmentier explained.

 "....the percentage of the Sun's surface covered by coronal holes seems to be a fairly accurate indicator of temperature in the Earth's troposphere over months or years." Spaceref.com

A solar comet?

http://spaceweather.com/images2015/20feb15/comet_anim.gif?PHPSESSID=i8oqdput2rdvsrgi6smtlb2pd7

"An unusual comet is skirting past the sun today. "It's a 'non-group comet,' meaning that it does not appear to be related to any other comet or comet family that we have on record," explains Karl Battams of the Naval Research Lab. "Unofficially I've labelled it SOHO-2875, as it's the Solar and Heliospheric Observatory's 2,875th comet discovery." Spaceweather.com
