Mauna Loa Solar Image
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.
Solar activity continued at very low levels. Region 2615 (S07W54, Dso/beta) continued its dissipation trend and produced only low-level B-class flares. An approximately 24 degree long filament centered about N17E72 became unstable and eventually disappeared by 07/1000 UTC as observed in GONG/H-alpha imagery. Initial analysis of available imagery indicated an eruptive nature to this activity and much of the plasma appeared to escape the Sun on a northeasterly vector. We await updated coronagraph imagery to confirm if a CME occurred in relation to this event, and if so, conduct further analysis to determine any potential geoeffectiveness. At the time of this discussion, no Earth-directed CMEs were observed in available coronagraph imagery.
Solar Activity Forecast
Issued: 2016 Dec 07 1230 UTC
Solar activity is expected to continue at very low levels, with a chance for C-class flares all three days (07-09 Dec). Energetic

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.
Auroral Activity Extrapolated from NOAA POES
Northern Hemi Auroral Map
Southern Hemi Auroral Map
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.
