The Deep Space Climate Observatory (DSCOVR) is scheduled to begin operations this summer giving early warning of solar storms. It was launched from Cape Canaveral on February 11, 2015. Essentially, it will replace the Advanced Composition Explorer (ACE) satellite (in operation at L1 since the late 1990s) with upgraded measurement capabilities.
An EOS Earth & Space Science News on-line article by Delores Knipp and Douglas Biesecker describes the mission:
SuperDARN: An International Collaboration
SuperDARN is made possible through the cooperation and funding of nine different countries... a true international effort!
Large geomagnetic storm occurs on St. Patrick's Day 2015 and produces aurora visible from Virginia
The aurora was photographed from a mountain near Blacksburg on the evening of March 17, 2015. See the News item or click on image for more information, Photo credit: Alex Thornton (Virginia Tech)
Total Solar Eclipse took place on March 20, 2015
Effects of the eclipse on the ionosphere were observed by SuperDARN radars. The track of totality is shown.
NASA MMS mission launched on March 12, 2015
Atlas 5 rocket carrying the MMS mission awaits liftoff at Cape Canaveral. MMS will make measurements in Earth's magnetosphere of processes that produce space weather.
The 2015 SuperDARN Workshop will be held in Leicester, UK, June 1-5, 2015
The Workshop website is now open for submitting abstracts and making reservations.

Welcome to SuperDARN!
SuperDARN stands for Super Dual Auroral Radar Network. The network consists of more than 30 low-power HF radars that look into Earth's upper atmosphere beginning at mid-latitudes and extending into the polar regions. The radars operate continuously and observe the motion of charged particles (plasma) in the ionosphere and other effects that provide scientists with information on Earth's space environment. The knowledge gained from this work provides insight into space weather hazards including radiation exposure for high-altitude travelers and disruptions to communication networks, navigation systems (GPS), and electrical power grids.
The SuperDARN Research Group at Virginia Tech (VT) collaborates with an international community of scientists and engineers to operate radars and share data. The VT Group operates five radars. For a summary of the radars and their affiliations, visit the Radar Maps/Tables/Links web page.
