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 was very low. Only mid level B-class flares were observed from Regions 2458 (N08W21, Cao/beta) and 2459 (N04E04, Axx/alpha). The largest flare was a B6/Sf at 29/0737 UTC from Region 2459. Slight growth was observed in the intermediate spots of Region 2458. Newly numbered Region 2461 (S07W54, Axx/alpha) emerged during the period with a lone spot and was inactive. No Earth-directed coronal mass ejections (CMEs) were observed during the period. A full-halo CME was observed in STEREO A COR 2 imagery beginning at 29/0824 UTC. Analysis concluded that this was a far-sided event as STEREO A EUVI imagery showed a correlated filament eruption on the backside around 29/0755 UTC.
Solar Activity Forecast
Issued: 2015 Nov 30 0030 UTC
Solar activity is expected to be at very low levels with a chance for C-class flares over the next three days (30 Nov-02 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.
