Another thing besides world economy I watch is Solar flares and earthquakes...this is the lastest.
EARTH-DIRECTED SOLAR FLARE: On Feb. 13th at 1738 UT, sunspot 1158
unleashed the strongest solar flare of the year so far, an M6.6-category
blast. NASA's Solar Dynamics Observatory recorded an intense flash of
extreme ultraviolet radiation, circled below: (see link)

The eruption produced a loud blast of radio waves heard in shortwave
receivers around the dayside of our planet. In New Mexico, amateur radio
astronomer Thomas Ashcraft recorded these sounds at 19 to 21 MHz. "This
was some of the strongest radio bursting of the new solar cycle," he
says. "What a great solar day."
Preliminary coronagraph data from
STEREO-A and SOHO agree that the explosion produced a fast but not
particularly bright coronal mass ejection (CME). The cloud will likely
hit Earth's magnetic field on or about Feb. 15th. High-latitude sky
watchers should be alert for auroras.

Now many oversea's folks think a HUGE earthquake will happen right after this flare hits earth up to a 3 days after...many are saying New Madrid, which Guy, Arkansas just had a 2.1...Chile is getting hammered the last 3 days with earthquakes...direct hit of flare will be South America but will effect the USA.
Just a FYI...use Sunblock if outside tomorrow.
Just some info to understand what this is about:
The average distance from the Sun to the Earth is 150 million kilometers
which can be written as 150 x 10^6 Km. CME's can vary in speed. They
can range from 200 km/s to 1000 km/s, although typically, most of them
travel at about 424 km/s (Avg 1996-1998 speed St. Cyr et al., 2000).
The
most powerful flare of the last 500 years was the first flare to be
observed, on September 1, 1859, and was reported by British astronomer
Richard Carrington. The event is named the Solar storm of 1859, or the
"Carrington event". The flare was visible to a naked-eye, and produced
stunning auroras down to tropical latitudes such as Cuba or Hawaii, and
set telegraph systems on fire.[7] The flare left a trace in Greenland
ice in the form of nitrates and beryllium-10, which allow its strength
to be measured today (New Scientist, 2005).
A coronal mass
ejection can make the 93-million-mile journey to Earth in just three to
four days. This implies an average speed of about one million miles per
hour.
Solar flares are classified by brightness at their X-ray wavelengths.
X-class is the largest flare.
M-class is a medium sized solar flare.
C-class is the smallest of the flares.
Numbers
are attached which are logarithmic, powers of 10. A class X-4 flare is
more than 10 times more energetic than a class X-3 flare would be.
