TOTAL LUNAR ECLIPSE: On Wednesday evening, February 20th, the full Moon over Europe and the Americas will turn a delightful shade of red. It's a total lunar eclipse—the last one until Dec. 2010. When should you look? Click here for an animated timetable.

PACIFIC FIREBALL: On Tuesday morning, Feb. 19th, at approximately 5:30 a.m. Pacific time, people in Washington, Oregon, Idaho and Montana witnessed a spectacular fireball. It exploded not once but twice in midair, casting shadows and rivaling city lights. Many onlookers wondered if spy satellite USA 193 had been shot down. No, it was a small asteroid breaking up in Earth's atmosphere, a surprisingly common event. Reports of meteorites hitting the ground remain unconfirmed; stay tuned for updates.

Sunspots Erupt Suddenly

The sun goes through an 11-year cycle of activity. The last peak, when sunspots were common and flares frequent, was in 2001 and 2002. The new cycle, Solar Cycle 24, began recently, scientists figure, based on a sunspot with reversed polarity appearing. But pinning down exactly when the shift occurred has proven challenging — it might have been in 2006, sun-watching scientists reported initially, or perhaps 2007, they later said.


Though forecasts vary wildly, some scientists predict Solar Cycle 24 will be intense. If so, "it could have significant impacts on telecommunications, air traffic, power grids and GPS systems," according to a NASA statement issued in December.

this is an interesting article
and it is scientific
get pased the mayan stuff
i find it hard to believe a bunch of blood thirsty
savages did that calendar
maybe it is pre flood
who knows
they knew about solar flares which we did not know about until the 17thy century
they invented the concept of 0 etc

so i have done s study on this you may find the following of interest

It's all about the Sun

It's ironic (or maybe not) that the Mayan Calendar is often called the "sun stone." While the calendar does have "solar" days, acknowledging the 365 days it takes for Earth to rotate around the Sun, it is also true that the Sun plays a key role in the final day of the "long count." To understand what will happen to the Sun on December 21, 2012, we need to review some scientific terms like "ecliptic," "barycenter," and "sunspots." These are important in the discussion that follows. We'll start with the most difficult one first.

[lighthouse]

What is the Barycenter?

You've no doubt heard that Earth revolves around the sun. Well, actually, that's not quite true!

Have you heard the term "center of gravity"? It's a technical-sounding term for something pretty simple. It's the exact center of all the material (that is, mass) that makes up the object. For example, if you have a straight stick, like a ruler or yardstick, there's a place at the middle where you can balance it on your finger. That's its center of gravity.



But the center of gravity may or may not be the point that is exactly in the middle, distance-wise, of the object. Some parts of the object may be heavier (denser) than others. If you have something like a sledge hammer that is heavier on one end than the other, the center of gravity will be much closer to the heavy end than the lighter end.



To get an idea of where the center of gravity is, rest the ends of any object like the ruler or a pencil on one finger from each hand. Slowly move your fingers together without dropping the object. Your fingers will meet underneath the object's center of gravity. You can balance the object on one finger at that special place.

The actual center of gravity could be close to the surface or deep inside, depending on whether the object is flat like a ruler or a dinner plate, or "three-dimensional," like a box or a ball. And if you let the object spin (like when you throw it), it will try to spin about that point.

In the case of the Earth and the sun, both bodies actually revolve, or spin, around the very center of the mass (similar to center of gravity) between them. This point is called the "barycenter." Earth and the sun are "connected" by the gravity pulling them together. It's just like the light end and heavy end of the sledge hammer. Compared to the size of the sun, Earth is about like a flea on a cat! So the center of mass between the Earth and the sun is almost--but not quite--the very center of the sun.

In the case of a planet the size of Jupiter, which is 318 times as massive as Earth, the barycenter of Jupiter and the sun is a bit further from the sun's center. So, as Jupiter revolves around the sun, the sun itself is actually revolving around this slightly off-center point, located just outside its center. Thus, a planet the size of Jupiter will make the sun (or any star) appear to wobble a tiny bit. This picture shows you that the center of mass and barycenter can be slightly different points. It isn't meant to be very accurate!



We can take advantage of this bit of knowledge and look for large planets in other solar systems by learning to detect this type of tiny wobble in the star's position.

For now, let's forget all the small planets and focus on Jupiter. It makes one complete trip around the Sun every 11.861773 years. There's a new theory put forth by Dr. Rollin Gillespie which shows that Jupiter, and to a smaller degree the other less massive planets, may trigger the 11 year cycle of sunspots and solar flares.

The barycenter is not a single point in the Sun. Because the Sun is a rotating gaseous sphere, the barycenter forms a vertical, cylindrical "sleeve" that is partially inside and outside the main solar body. All of the planets have such a "sleeve," one inside the other, depending on their relative mass and the location of their barycenters. The particular sleeve representing the mass of Jupiter intersects the solar surface at 35.9 degrees North and South. This is precisely where sunspot and flare activity begin and end during each 11 year cycle.

The new cycle has already begun with the recent observation of a solar spot with reverse polarity. But some surprising activity on March 27, 2008, shows some huge eruptions with M-class radiation at about the equatorial region of the Sun. [ See Solar Map]. These surprising eruptions suggests a barycenter of disturbance from an object even more massive than Jupiter, placing the "sleeve" outside the Sun. Could this be the beginning of the Galaxy's effects (keep reading to learn more about this) on our Sun?

Scientists have noted that when Jupiter and Saturn are aligned on the same side of the Sun, the solar activity is at its minimum; when they are on opposite sides of the Sun the solar activity is at its maximum. The positions on December 21, 2012 are ideal for extreme solar activity.
