iNTEGRATED SPACE WEATHER ANALYSIS SYSTEM

ISWA is a flexible, turn-key, Web-based dissemination system for NASA-relevant space weather information that combines forecasts based on the most advanced space weather models with concurrent space environment information. iSWA is customer-configurable and adaptable for use as a powerful decision-making tool. The system offers an unprecedented ability to analyze the present and expected future space weather impacts on NASA’s human and robotic missions. iNTEGRATED SPACE WEATHER ANALYSIS SYSTEM

Today's Space Weather The Satellite Environment Plot combines satellite and ground-based data to provide an overview of the current geosynchronous satellite environment. Click on a data panel to open an updating secondary window. An updating Satellite Environment Plot window is also available. Although these data are of interest to the satellite community, they do not include all parameters and energy ranges known to be associated with satellite anomalies. See related information from the NOAA POES satellite -- Auroral Activity Estimates, Relative Intensities of Energetic Particles, and Solar Protons. Today's Space Weather

The GOES X-ray flux plot contains 1 minute averages of solar X-rays in the 1-8 Angstrom (0.1-0.8 nm) and 0.5-4.0 Angstrom (0.05-0.4 nm) passbands. Data from the SWPC Primary GOES X-ray satellite is shown. As of Feb 2008, no Secondary GOES X-ray satellite data is available. Some data dropouts will occur during satellite eclipses. 6-hour GOES X-ray Flux Monitor 6-hour GOES X-ray Flux Monitor
The GOES X-ray Flux plot contains 5 minute averages of solar X-ray output in the 1-8 Angstrom (0.1-0.8 nm) and 0.5-4.0 Angstrom (0.05-0.4 nm) passbands. Data from the SWPC Primary and Secondary GOES X-ray satellites are shown. Some data dropouts from the Primary satellite will occur during satellite eclipses. Other plots of interest: A white background version of this plot; GOES 1-min X-rays; SWPC Real-time Monitors. SWPC X-ray alerts are issued at the M5 (5x10E-5 Watts/m2) and X1 (1x10E-4 Watts/m2) levels, based upon 1-minute data. Large X-ray bursts cause short wave fades for HF propagation paths through the sunlit hemisphere. 3-day GOES X-ray Flux Monitor 3-day GOES X-ray Flux Monitor
