Front Page News
A new version of the radar software toolkit (RST) has been released by the Data Analysis Working Group and can be found on the working group's github repository(external link) as version 4.1. Some major changes come with this new version including the deprecation of the '-new' flag in favor of using '-old' for data formats prior to 20060701 (*.dat, *.fit, etc.). The '-new' flag will no longer work and may break processing if used, so please update any external processing code.

In addition, RST 4.1 comes with major revisions to the gridding and mapping software. This means RST 4.1 will no longer produce the grdex and mapex files that are found on the VT-SuperDARN website. New files produced with the RST 4.1 code will be called grid2 and map2. These new files retain much of the same format as grdex and mapex files but are being separated to distinguish between the major revisions in the gridding and mapping software. RST 4.1 does maintain backwards compatibility so grdex and mapex files should be read and plotted with the current code.

Lastly, RST 4.1 introduces fitacf 3.0 as an experimental option of processing rawacf files into fitacf files. The default for this processing remains with fitacf 2.5, but users have the option to process what we at Virginia Tech are calling fitacf3 files with the command 'make_fit -fitacf-version 3.0'.

For now, grdex and mapex files will be produced to the end of 2017. Grid2 and map2 files will be produced starting with the beginning of 2017, but could be extended further back in time as necessary. Also, starting with the beginning of Dec. 2017, fitacf3 files will be produced in addition to fitacf (v2.5) files. Some of the web tools found on this website have been updated to plot this data. For the latest on what is available in the VT database, please refer to the data inventory page.

Prof. Mark Lester has passed on the exciting news that Dr. Suzie Imber from Leicester University has won a BBC-sponsored contest entitled 'Astronauts: Do you have what it takes?' to receive a reference from NASA Astronaut Commander Chris Hadfield to be accepted into the ESA astronaut training program. Suzie is a graduate of Leicester University where she was advised by Prof. Steve Milan. She has worked as a Research Scientist at NASA GSFC and is currently Associate Professor at Leicester. Mark has passed on the following notes:

"Suzie Imber, who has made several contributions to the SuperDARN group, was selected as one of 12 contestants from an original pool of applicants of well in the thousands and reached the last 3 of the competition. In the final episode of the series it was announced that Suzie had won the competition. Many congratulations to Suzie!" Also see

Web page for ERG (ARASE) mission now available

By: miker  on: Sun., July 30, 2017 05:14 PM EDT  (2271 Reads)
Yoshi Miyoshi (Arase/ERG Project Scientist) announced on July 31, 2017 that a web page for Arase quick-look data is now available. Click on *Read More* for details.
The ERG (Arase) satellite has now been in full operation since March 24.

The Exploration of energization and Radiation in Geospace (ERG) satellite mission was launched on December 20, 2016 with an Epsilon rocket from the Uchinoura Space Center on the southern Japanese island of Kyushu. The aim of the mission is to study Earth's radiation belts. Coordinated operations are planned with the SuperDARN radars. Shortly after launch the satellite was officially nicknamed "Arase", which is a Japanese word for a river raging with rough water and also the name of a river close to the Uchinoura Space Center.

Great American Eclipse to cross the U.S. from coast to coast on August 21, 2017

By: miker  on: Sun., June 25, 2017 07:31 PM EDT  (2618 Reads)
A total solar eclipse will take place in 2017 on Monday, August 21. The path of totality will cross the continental U.S. from west to east as indicated in the map in about 90 minutes. All of the continental U.S. will experience at least a partial eclipse. Totality will last a maximum of 2 min 40 sec at any one place. The effects in the ionosphere will be observed by the SuperDARN radars located at Christmas Valley (Oregon) and Hays (Kansas) running special modes. This effort is part of a comprehensive project funded by the NSF CEDAR program to study the eclipse that is being lead by Prof. Greg Earle (Virginia Tech).
A set of maps showing the path of totality state-by-state can be found at

The Royal Astronomical Society has bestowed the 2017 Group Achievement Award in geophysics, solar physics, and solar-terrestrial physics on the international SuperDARN collaboration. Announcement of the award was made at the Ordinary Meeting of the Society held on January 13, 2017. The award will be presented at the Society's National Astronomy meeting in Hull in July to Prof. Mark Lester, Chair of the SuperDARN PI Committee. The on-line announcement of the 2017 RAS awards, medals, and prizes is found at https://www.ras.org.uk/awards-and-grants/awards/2943-winners-of-the-2017-awards-medals-and-prizes-full-details(external link)
