Get the current X-ray data. High X-ray flux readings can mean trouble for communicating via short wavelengths (high frequency). High X-ray levels from the Sun usually indicate that a solar flare is occuring. Strong solar flares usually preceed a Geomagnetic storm. The flare's magnitude is usually proportional to the amount of material ejected (CME) and to the strength of the magnetic fields that twist through the CME material. | |
|
Gives graph of data recorded by the ACE spacecraft. This data includes the Interplanetary Magnetic Field (Bz), velocity of the solar wind, as well as other statistics. Bz values less than zero are sometimes a good indicator to be on the lookout for Aurora. Negative Bz values and a fast solar wind speed are almost always your best bet. The time period to see aurora is right after a CME hits the planet's Magnetosphere- an event known as a 'sudden impulse' when referring to Bz, and a 'transient passage' when looking at solar wind speed values. | |
| Satellite
Environment Plot |
Gives the graphs of several space weather variables. Includes the Kp, Hp indices, as well as Proton and Electron Flux. High proton levels in the vicinity of Earth can cause polar regions to absorb radio waves, making communication difficult. Hp indices can be used to check for impacts of CMEs. |

| Current
Planetary Kp Index Graph |
The Kp
index is an indication of geomagnetic disturbance. Values above 4 indicate
storm conditions. Storm conditions may bring Aurora and other phenomena.
If the Kp index is 5 or above, we here in Maine should be on the lookout
for Aurora. Places to the south (VA) will need to have higher Kp values
to see Aurora. You can find a map of Geomagnetic Latitude (not geographic latitude! declanation...) here, which is helpful. |

Sun Pix |
More pictures of the sun in various wavelengths; also includes a few magnetograms of the sun as well. Each picture gives a unique look at the different faces of the sun. |

| Look
Through The Sun! |
This new technique is called Helioseismic
Holography. An instrument aboard the SOHO
spacecraft 'listens' to oscillations in the Sun, and can determine locations
of large magnetic flux. Magnetic fields poking through the Photosphere
in the sun are the cause of sunspots.
