Spring GOES-14 XRS Eclipse Season Feb 27 - Apr 14
During the spring and fall, GOES-14 experiences eclipses in which the Earth blocks the X-ray instrument view to the sun for short periods once each day. For spring 2010 this period will run from Feb. 27 to Apr. 12, 2010. Eclipses ranging from minutes to just over an hour occur around 0700 UT. At these times there will be a dip or gap in the XRS signal shown.

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 Cycle Progression Solar Cycle chart updated using the latest ISES predictions. |
|
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. |

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.

Potentially
Hazardous Asteroids (PHAs)
are space rocks larger than approximately 100m that can come
closer to Earth than 0.05 AU. None of the known PHAs is on
a collision course with our planet, although astronomers are
finding new
ones all the time.
On
March 21, 2010 there were 1110 potentially
hazardous asteroids.

2010 Earth-asteroid encounters:
LD means "Lunar Distance." 1 LD = 384,401 km, the distance between Earth and the Moon. 1 LD also equals 0.00256 AU. MAG is the visual magnitude of the asteroid on the date of closest approach. |
