Having marked its first anniversary on orbit, NASAs Solar Radiation and Climate Experiment (SORCE) satellite has hit its stride. In concert with other satellites, SORCEs observations of the suns brightness are helping researchers better understand climate change, climate prediction, atmospheric ozone, the sunburn-causing ultraviolet-B radiation and space weather.

In fall 2003, SORCE was fortunate to see and measure exceptionally high levels of the suns activities. In late October and November the sun sent solar flares and coronal mass ejections hurtling Earthward, disrupting satellites and other transmissions, triggering an intense geomagnetic storm, and enabling sightings of the northern lights as far south as Arkansas, Texas and Oklahoma.
The third most powerful solar flare ever observed in X-rays, high-energy photons with very short wavelengths, erupted from Sunspot 486 October 28, 2003, at approximately 6 a.m. Eastern Standard Time. The same spot released a large X11 flare on the afternoon of October 29. As the sunspot moved across the face of the sun, total solar brightness decreased by 0.3 percent.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
