Il sole è costantemente monitorato per macchie solari e le esplosioni di massa coronale. EIT (Extreme UV Imaging Telescope) immagini dell'atmosfera solare a diverse lunghezze d'onda e, quindi, mostra materiale solare a differenti temperature. Nelle immagini prese a 304 Angstrom il materiale luminoso è da 60.000 a 80.000 gradi Kelvin. In quelle prese a 171 Angstrom, a 1 milione di gradi. 195 Angstrom corrisponde a circa 1,5 milioni di Kelvin, 284 Angstrom a 2 milioni di gradi. Più calda la temperatura, più si guarda nell'atmosfera solare.

Real Time Solar X-ray and Solar Wind

Solar Cycle Progression

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

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.
