El sol es monitoreado constantemente pormanchas solares y eyecciones de masa coronal. IET (Extreme ultravioleta Imaging Telescope) imágenes de la atmósfera solar en varias longitudes de onda , y por lo tanto , muestra material solar a diferentes temperaturas. En las imágenes tomadas a 304 Angstrom el material brillante es en 60.000 a 80.000 grados Kelvin. En las tomadas en 171 Angstrom , en 1 millón de grados. 195 imágenes Angstrom corresponden a alrededor de 1,5 millones de Kelvin , 284 Angstrom a 2 millones de grados. Cuanto más caliente esté la temperatura , cuanto más alto se observa en la atmósfera solar

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 was expected to occur in May, 2013.

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.
