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:

Total Solar Eclipse to Sweep over Svalbard on March 20, 2015

A total solar eclipse will take place on March 20. The path of totality will pass over Svalbard at 10:10 UT and sweep through the fields of view of multiple SuperDARN radars. Totality will last for 2 min 47 seconds. The accompanying plot shows the path of the eclipse with time stamps (credit: Muhammad Rafiq - VT).

Aurélie Marchaudon of IRAP/CNRS is making the arrangements to schedule SuperDARN radars to run in Discretionary Time (DT) for the period 20 March, 08 - 16 UT. One focus of the run will be to observe AGWs caused by the eclipse.

Launch of NASA MMS Satellite from Cape Canaveral

The NASA Magnetospheric Multiscale mission (MMS) launched as scheduled on March 12, 2015 at 10:44 EDT from Cape Canaveral carried by a United Launch Alliance Atlas 5 rocket.

Quoting from the NASA MMS website at http://mms.gsfc.nasa.gov/(external link) : 'The Magnetospheric Multiscale (MMS) mission is a Solar Terrestrial Probes mission comprising four identically instrumented spacecraft that will use Earth’s magnetosphere as a laboratory to study the microphysics of three fundamental plasma processes: magnetic reconnection, energetic particle acceleration, and turbulence.'

The science phase of the mission is scheduled to begin in September. SuperDARN is planning to operate in supporting modes.

SuperDARN-Related Article Provides Cover Page for JGR October issue

By: miker  on: Thu., Dec. 04, 2014 02:40 PM EST  (644 Reads)
An article lead-authored by graduate student Christer van der Meeren of the Birkeland Centre for Space Science at the University of Bergen has been selected to provide the cover image for the October 2014 issue of the Journal of Geophysical Research - Space Physics. The article examines the occurrence of GPS scintillations and irregularities in relation to a tongue of enhanced ionization that extends into the nightside ionosphere at polar latitudes.

The cover image shows a sequence of maps of total electron content (TEC) obtained from GPS measurements with simultaneous convection patterns obtained from analysis of SuperDARN velocity data overlaid. The circle indicates the field of view of instrumentation located on on Svalbard.

Christer is advised by Prof. Kjellmar Oksavik. The figure was generated with the help of the on-line GPS/TEC plotting tools developed by graduate student Evan Thomas at Virginia Tech and collaborators at MIT Haystack Observatory.


Australian SuperDARN Researchers Win Awards for Excellence in Engineering Innovation

Australian SuperDARN researchers lead by the La Trobe University group and PI John Devlin have been recognized with prestigious awards for excellence in engineering innovation in connection with the design of the Buckland Park digital radar. In September they received the 2014 Victorian Engineering Award for Excellence. In November they were presented with the 2014 Australian Engineering Excellence Award for Innovation. Announcement of the latter can be found on the 'Engineers Australia' web site:
