1Umbral magnitude is the fraction of the Moon’s diameter obscured by Earth’s Umbra. For penumbral eclipses, the umbral magnitude is always less than 0. For partial eclipses, the umbral magnitude is always greater than 0 and less than 1. For total eclipses, the umbral magnitude is always greater than or equal to 1. 2Eclipse Duration is the duration of a partial eclipse. If the eclipse is total, the duration of totality is given in bold.
3Geographic Region of Eclipse Visibility is the portion of Earth’s surface where a lunar eclipse can be seen.

Solar X-ray Flux
This 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 both operational GOES satellites are included. Some data dropouts will occur during satellite eclipses. SEC alerts are issued at the M5 (5×10E-5 Watts/m2) and X1 (1×10E-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. Some large flares are accompanied by strong solar radio bursts that may interfere with satellite downlinks.
This page updates dynamically every 5 minutes.
This plot combines satellite and ground-based data in an attempt to present an overview of the current satellite envionment (particularly at geosynchronous altitude). 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.

Filamentary structure in 3D. Image credit: SubaruClick to enlarge
Astronomers have used the Subaru and Keck telescopes to discover gigantic filaments of galaxies stretching across 200 million light-years in space. These filaments, formed just 2 billion years after the Big Bang, are the largest structures ever discovered in the Universe. The filaments contain at least 30 huge concentrations of gas, each of which contains 10x the mass of the Milky Way.

Galaxy NGC 908. Image credit: ESOClick to enlarge
This photograph of galaxy NGC 908 was taken with the European Southern Observatory’s Very Large Telescope. This spiral galaxy was first discovered in 1786 by William Herschel, and is considered a starburst galaxy. Clusters of young, massive stars pepper its spiral arms indicating regions of furious star formation. NGC 908 must have had a recent encounter with another galaxy; the gravitational interaction between the galaxies caused gas clouds to collapse, igniting star formation.
