Part of an article I recieved the link to the whole thing is at the bottom.


A new and powerful sunspot complex has materialized over the last 2 days
capable of producing significant solar flare activity. The sunspot complex,
known as active Region 10484 (or simply Region 484), increased its size by
more than 5 times over the last 48 hours. It should now be easily visible to
the unaided (protected!) eye.

Region 484 produced a major class X1.1 solar x-ray flare at 16:51 UTC
(12:51 pm EDT) on 19 October followed by several smaller but notable events.
Growth has persisted despite this activity and additional major solar flares
are expected.

There is a notable possibility that some lucky observers may spot a
rare white-light flare from this spot complex. The area to concentrate on
(observationally) is the penumbral region between the two largest sunspots.
These two sunspots form a magnetic delta configuration where opposite
magnetic polarity sunspot umbrae are contained within a single penumbra. This
is also the site where most of the energetic solar flare activity has been
observed to-date. See for details.

Thus far, the coronal mass ejections associated with the energetic
flaring from Region 484 have not been directed Earthward, although there is a
chance the Earth may see a weaker glancing blow within the next 24 to 48
hours. This is expected to change over the next several days.

Over the next 4 days, Region 484 will rotate toward the central region
of the Sun (as viewed from the Earth). It will therefore be more radially
aligned and capable of producing more signifcant Earthbound coronal mass
ejection impacts. These impacts could include proton bombardments capable of
affecting high-latitude radio signal communications and enhancing space
radiation conditions for satellites and astronauts, increased atmospheric
drag on spacecraft, increased incidents of electronic anomalies on
spacecraft, permanent degradation of spacecraft solar array electrical
generation efficiencies, and unusual displays of auroral activity ("Northern
Lights"), to name just a few."" target="_blank" class="postlink" rel="nofollow">

Thanks for the info.
I posted on this topic yesterday..

Im new to this website so I have been skipping around and have not had time to read many of the posts. Sorry for posting about the same thing twice.
My Cell phone seems to jog in and out of signal when these solar flares happen. Usually when my phone starts to act crazy I'll check the web and sure enough there is solar activity.

More sun activity......Here is the artical
Solar Terrestrial Dispatch

22 October 2003


It is an established fact that intense regions of solar activity can
occur at just about any time during the ~11 year solar cycle. Although they
appear more frequently during the years immediately around the solar maximum,
they can also occur well into the declining years closer to the solar
minimum. We are currently observing one of those periods.

Not one, but TWO intense active regions are now visible on the Sun.

The first and thus far the largest region (Region 484) was mentioned in
the last AstroAlert. It now covers an area of more than 5,200 million square
kilometers. That is larger than the surface areas of all of the inner planets
(Mercury, Venus, Earth and Mars) combined - with more than enough room left
over for an additional planet having the surface area of the Earth)! Region
484 is easily visible to the unaided (but protected!) eye.

Another active region has just rotated into view around the
southeastern limb of the Sun. John McConnell, an avid solar observer,
notified us today that this region is now visible on the limb. It's size is
still difficult to discern given its proximity to the limb. But it has proven
to be a powerful sunspot complex capable of very energetic activity.

Beginning at about 19:30 UTC yesterday (3:30 pm EDT) and while still
behind the east limb of the Sun, this region produced a long-duration flare.
The tops of the solar explosion were visible as the activity rose above the
surface of the Sun. Several hours later, at 03:24 UTC on 22 October (or 11:24
pm EDT on 21 October), this region produced a very long duration solar flare.
X-rays from this event remained above M-class levels for a remarkable 8 full
hours! The total energy released from this event was comparable to the energy
released in a typical major X-class solar flare. Coronal mass ejections were
associated with both of these events.

As this region rotates toward the Earth over the next week, it may
produce additional coronal mass ejections capable of producing stronger space
weather storms and associated periods of stronger auroral activity ("Northern

Either of these two strong centers of solar activity are capable of
producing minor to major solar flares."
