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

By: miker  on: Thu., Mar. 16, 2017 07:31 PM EDT  (245 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

VT student researchers decode Ham radio transmissions received by Canadian satellite

By: miker  on: Fri., July 24, 2015 04:55 PM EDT  (1377 Reads)
A news bulletin issued by the National Association for Amateur Radio (ARRL) describes an experiment spearheaded by Virginia Tech students led by PhD candidate Nathaniel Frissell to detect transmissions from Ham radio stations with the Enhanced Polar Outflow Probe (ePOP) Radio Receiver Instrument (RRI) on-board the CASSIOPE satellite. A total of 23 stations, mostly in mid-western states, were detected during an ARRL Field Day on June 28. The reception of signals at 7 MHz but not 3.5 MHz was explained on the basis of ionospheric density levels measured by an ionsonde located at the Millstone Hill Observatory in Massachusetts. The operation of the ePOP instrument is managed by Dr. Gareth Perry at the University of Calgary. Read the ARRL bulletin at

VT Students Attend 2012 ISR Summer Workshop

By: Nathaniel Frissell  on: Sat., Aug. 04, 2012 10:01 PM EDT  (2288 Reads)
Ph.D. students Bharat Kunduri and Nathaniel Frissell spent this past week in Banff, Canada at the 2012 NSF Incoherent Scatter Radar (ISR) Summer School. During the week, they attended lectures given by leading international researchers in the field of ISR and interacted with other space science students from around the world.

Incoherent scatter radar is a type of radar that is able to remote sense ionospheric plasma properties such as electron density, ion and electron temperature, and ion velocities. This is done by measureing the ion acoustic and plasma waves using very large radars that operate at frequencies typically around 500 MHz with approximately 2 megawatts of power or more. ISRs often complement SuperDARN radars, which are coherent scatter radars. This is because ISRs are able to provide plasma measurements SuperDARN can not, but have much smaller spatial coverage. Also, unlike SuperDARN which operates continuously, ISRs can typically only be operated for limited amounts of time.

Visit to USS Manufacturing

By: ksterne  on: Thu., June 14, 2012 05:35 PM EDT  (2838 Reads)
Front Page News
Update 6/16/2012: I've since left the USS Manufacturing shop in Renfrew, Ontario and toured some through Canada. Upon leaving the shop at USS, there were a few remaining issues, only a small one of which for the upcoming build at Adak Island. One thing that was communicated very well to the guys at USS Manufacturing, was our problem with the 1/2" shackles at the base of the 56' poles as seen in the picture to the right. These poles were quickly brought inside and a air-powered dremel tool was used to easier make the hole bigger such that the 1/2" shackle would fit into the hole. Upon leaving the shop in Renfrew, it was determined that the set of poles and hardware for Renfrew could go out early next week, probably on Tuesday and take about 5 days to get to Seattle.
