Next solar storm cycle will start late

April 27th, 2007 by

The next 11-year cycle of solar storms will most likely start next March and peak in late 2011 or mid-2012 — up to a year later than expected — according to a forecast issued by the U.S. National Oceanic and Atmospheric Administration’s Space Environment Center in coordination with an international panel of solar experts.

STEREO spacecraft make first 3-D images of Sun

April 25th, 2007 by

NASA’s twin Solar Terrestrial Relations Observatory (STEREO) spacecraft have made the first three-dimensional images of the sun. The new view will greatly aid scientists’ ability to understand solar physics and thereby improve space weather forecasting, the agency said.

LM scientists determine magnetic reconnection locations

February 18th, 2007 by

Scientists from the Lockheed Martin Advanced Technology Center (ATC) are using data from the Toroidal Imaging Mass Angle Spectrograph (TIMAS)–an ATC instrument launched on the NASA Polar spacecraft in 1996–to determine how and where the energy from the solar wind is transferred into the Earth’s magnetosphere.

ESA develops space weather tool to protect satellites

February 3rd, 2007 by

Since early 2005, SEISOP (Space Environment Information System for Operations), a space-weather monitoring and forecasting tool under development at ESA’s Space Operations Centre, has been successfully providing near-real-time space weather reports for Integral, ESA’s gamma-ray space observatory. In 2007, SEISOP will enter operational development aimed at providing all ESA missions with the same vital space weather updates, the agency said.

Recent solar outburst produced record amount of radio noise

December 16th, 2006 by

A solar outburst on 6 December produced a record amount of radio noise, said solar physicist Dale Gary, chair of the department of physics at New Jersey Institute of Technology (NJIT). Owing to a computer software failure, initial research reports in the U.S. downplayed the outbursts.

Space weather affects satellites, ISS

December 16th, 2006 by

Recent solar activity has forced ESA mission controllers to react to anomalies or take action to avoid damage to spacecraft. Several missions, including Integral, Cluster and Envisat, felt the storm’s effects. Apparently, the International Space Station’s attitude control system was also affected.
