Global Ionospheric (TEC) Maps
GPS users with single-frequency receivers need ionospheric electron content information in order to achieve positioning accuracy similar to dual-frequency receivers. The GDGPS System provides a global real-time maps of ionospheric electron content (currently producing a map every 5 minutes). These maps are also of value in monitoring the effect of the ionosphere on radio signals, power grids, and on space weather.

Comet Lovejoy came into LASCO's view on Dec. 14 as a bright, white streak, skimmed across the Sun's edge about 140,000 km above the surface late Dec. 15 and early Dec. 16, 2011, furiously brightening and vaporizing as it approached the Sun...
STEREO
STEREO consists of two space-based observatories - one ahead of Earth in its orbit, the other trailing behind. With this new pair of viewpoints, scientists will be able to see the structure and evolution of solar storms as they blast from the Sun and move out through space.
SWPC - D-RAP
Conditions in the D region of the ionosphere have a dramatic effect on high frequency (HF) communications and low frequency (LF) navigation systems.

Solar activity remains very low with only B-Class X-Ray activity detected mostly around Sunspot 1450 and region 1451. The leader spot located within 1450 did show some growth over the past 24 hours.

The disturbance index is defined over two distinct latitude ranges (low latitudes -20 - 0°; mand mid latitudes -50 - -20°;) in the Australasian longitude sector (110 - 180°E longitudee), as the median TEC deviation in each region.

SOLAR STORM HEATS UP EARTH'S ATMOSPHERE: A flurry of solar activity in early March dumped enough heat in Earth's upper atmosphere to power every residence in New York City for two years. The heat has since dissipated, but there's more to come as the solar cycle intensifies. [ full story ] [ video ]
