GOES-14 eclipse season begins

August 26, 2010: GOES-14 eclipse season begins August 26 and lasts through September. The GOES Solar X-ray Flux plots and lists will have a daily data outage of up to one hour. The longest outage is Sept 14 from 0623 to 0728 UTC.

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.

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

Auroral Activity Extrapolated from NOAA POES

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.

  • On the Move

    As if surrounded by a celestial halo, space shuttle Discovery made its way towards the expansive confines of NASA Kennedy Space Center's Vehicle Assembly Building following a move from its processing hangar on Sept. 9, 2010. A metal sling will be carefully connected to the spacecraft and then operators will hoist it from transfer aisle to the high reaches of the 52-story building before lowering it into place beside the external fuel tank and twin solid rocket boosters. Crews then will connect the spacecraft giving the stack its familiar launch day form. Discovery is targeted to liftoff on the 11-day STS-133 mission on Nov. 1 at 4:40 p.m. EDT.
