The sun is constantly monitored for Sun Spots and
coronal mass ejections. EIT (Extreme ultraviolet Imaging
Telescope) images the solar atmosphere at several wavelengths, and therefore, shows solar material at different temperatures.
In the images taken at 304 Angstrom the bright material is at 60,000 to 80,000 degrees Kelvin.
In those taken at 171 Angstrom, at 1 million degrees.
195 Angstrom images correspond to about 1.5 million Kelvin, 284 Angstrom to 2 million degrees.
The hotter the temperature, the higher you look in the solar atmosphere.

Real Time Solar X-Ray and Solar Wind
Solar Cycle Progression  Solar Cycle chart updated using the latest ISES predictions. |
Real-Time Solar Wind  Real-Time Solar Wind data broadcast from NASA's ACE satellite. |
The Solar Cycle is observed by counting the frequency and placement of sunspots visible on the Sun. Solar minimum occurred in December, 2008. Solar maximum is expected to occur in May, 2013.
Solar X-Ray Flux  This plot shows 3-days of 5-minute solar x-ray flux values measured on the SWPC primary and secondary GOES satellites. |
Satellite Environment Plot  The Satellite Environment Plot combines satellite and ground-based data to provide an overview of the current geosynchronous satellite environment. |

Real-Time Solar Wind
Real-Time Solar Wind data broadcast from NASA's ACE satellite. |
Instruments on board the NOAA Polar-orbiting Operational Environmental Satellite (POES) continually monitor the power
flux carried by the protons and electrons that produce aurora in the atmosphere. SWPC has developed a technique that
uses the power flux observations obtained during a single pass of the satellite over a polar region (which takes about
25 minutes) to estimate the total power deposited in an entire polar region by these auroral particles. The power input
estimate is converted to an auroral activity index that ranges from 1 to 10.
