just to let peoples know these images only remain for 24 hours and everybody must see,the earth magnetosphere waved and failed allowing ionispheric ions from sun to hit earth momentarily ,checkout the tear in the global earth ionisphere centre to left.
FIRST X-FLARE OF THE NEW SOLAR CYCLE: Sunspot 1158 has unleashed the strongest solar flare in more than four years. The eruption, which peaked at 0156 UT on Feb. 15th, registered X2 on the Richter scale of solar flares. NASA's Solar Dynamics Observatory recorded an intense flash of extreme ultraviolet radiation, circled below:
X-flares are the strongest type of solar flare, and this is the first such eruption of new Solar Cycle 24. In addition to flashing Earth with UV radiation, the explosion also hurled a coronal mass ejection (CME) in our direction. The expanding cloud may be seen in this movie from NASA's STEREO-B spacecraft. Geomagnetic storms are possible when the CME arrives 36 to 48 hours hence. Stay tuned for updates.

roduct: Geophysical Alert Message wwv.txt :Issued: 2011 Feb 15 1810 UTC # Prepared by the US Dept. of Commerce, NOAA, Space Weather Prediction Center # # Geophysical Alert Message # Solar-terrestrial indices for 14 February follow. Solar flux 113 and mid-latitude A-index 8. The mid-latitude K-index at 1800 UTC on 15 February was 2 (13 nT). Space weather for the past 24 hours has been strong. Radio blackouts reaching the R3 level occurred. Space weather for the next 24 hours is expected to be minor. Radio blackouts reaching the R1 level are expected.
ACE RTSW News and Announcements Introduction Geomagnetic storms are a natural hazard, like hurricanes and tsunamis, which the National Oceanic and Atmospheric Administration (NOAA) Space Weather Prediction Center (SWPC) forecasts for the public's benefit. Severe geomagnetic storms cause communications problems, abruptly increase drag on spacecraft, and can cause electric utility blackouts over a wide area. The location of ACE at the L1 libration point between the earth and the sun will enable ACE to give about a one hour advance warning of impending geomagnetic activity. NOAA has arranged for the transmission of a subset of data from four ACE instruments during the times when ACE is not transmitting it's full telemetry to the Deep Space Network. For about 21 of 24 hours per day, ACE will send data (~464 bps) to NOAA operated ground stations. During the other three hours when NASA is getting high rate data through the Deep Space Network, NOAA will get a copy of the real time data. NOAA will process all the data (using algorithms provided by the ACE experimenters) at its Space Weather Operations (SWO) in Boulder, Colorado, which will issue any warnings of expected geomagnetic activity.

Thats untrue as there are other planets in our solar system that do not have a magnetosphere and they are still spinning,all be it they are highly radioactive and dangerous to live on with extreme heat to cold on rotation and unbearable to live on..
Explanation of Frames of Reference
Astronomers observing the Moon noticed that it seems to be rotating on its axis in precise synchronization with its orbital speed, but their conclusion is wrong. A close examination would reveal the Moon does not rotate at all and is void of spin. Here is an experiment that can be conducted in your elementary astronomy labs. First the definition of rotation about its axis: when an object rotates 360 degrees about its central point within a set reference field. A set up a simple clear rigid plastic square sheet drill a hole in its center and suspend an attached sphere at its central axis with a string and the other end to the hole. Draw a straight reference between both points in which the rotational axis pierces the surface of the sphere and follows its curved surface. As a reference, mark a point on the perimeter of the square establishing as a lineup for the minimum distance between the line drawn between the axis of the suspended sphere and the marked point. Rotational spin within the grid is defined as the axis line moving away from the reference point and returning to the reference point in the same direction. Absence of rotation, the points of the axis line and grid reference remain aligned. Now attach a rigid rod to the frame of reference, if we move the grid away a point of origin at a set speed in a straight line does the parameters for rotation within the grid change as we view it while holding the grid away perpendicular to our motion? No. The next condition is for you move grid forward along a curved path and observing a reference of no rotation the points maintain alignment within the grid. When spin is applied and the sphere rotates 360 degrees in the same direction, if you move the grid forward along a curved path, you observe the sphere rotates. Again as you notice the sphere with no rotation, you constantly see the reference point and the axis line locked. If it spins you see all sides of the sphere. Now if you hold the grid and turn in an arc about a rigid point if the is no spin you constantly see the reference point and axis line. Apply a spin of 1 rotation you see all sides. If during that time you also pivoted 360 degrees about the same point you still observed all sides of the sphere during the turn. Looking at the total picture we find that a sphere with no rotation when pivoting about a point presents the same view of the reference point and axis line. In the second part when the speed of the rotation of the sphere to completes 1 rotation within the grid was matched to pivoting about 360 degrees in synchronization you still see all sides. Now realize the Moon is the sphere within the grid and the pivot point is Earth does this change the observations? No. Can astronomers present a simple experiment with models that backs the how Moon rotates?
Ok I had some time so I just want to point out, this is not true. Now, I understand that the moon and venus are not fully explained, they have theories on their spins. In short, they don't spin. They're not magnetized, and they always face us in the same position. If there is anything there its got something unusual to it, with anohter explanation, in other words its not your normal spin on axis, or its non-existant. It takes magnetic poles, or a magentized core and all those currents to do it.
New evidence from NASA's Mars Global Surveyor (MGS) spacecraft supports a long-held suspicion that much of the Red Planet's atmosphere was simply blown away -- by the solar wind. Right, above: Earth is shielded from the solar wind by a magnetic bubble extending 50,000 km into space -- our planet's magnetosphere. Right, below: Without a substantial magnetosphere to protect it, much of Mars's atmosphere is exposed directly to fast-moving particles from the Sun.
For all of its differences, here’s one situation where Mars is very similar to Earth. Mars’ rotation is 24 hours, 39 minutes, and 35 seconds. In other words, Mars only rotates 39 minutes more slowly than Earth.
