The Ham Radio Science Citizen Investigation (HamSCI) is an international collective of professional researchers and amateur radio operators working together to simultaneously advance the fields of space science and amateur (ham) radio activities. The 2nd US HamSCI meeting was held March 22-23, 2019, organized by Nathaniel Frissell of the New Jersey Institute of Technology (NJIT) and hosted by the Case Amateur Radio Club (Case ARC) at Case Western Reserve University (CWRU) in Cleveland, OH. The theme of this year’s meeting was “Ionospheric Effects and Sensing,” which includes the use of amateur radio techniques for the characterization and observational study of ionospheric phenomena such as traveling ionospheric disturbances, sporadic E, response to solar flares, geomagnetic storms, and other space weather events.
HamSCI will again be at the Dayton Hamvention as part of the new Ham Radio 2.0: Innovation and Discovery area sponsored by the Yasme Foundation. Come visit the HamSCI Booth and Forum to learn about projects on the cutting edge of ham radio science and engineering research, including new directions in Sporadic E research, causes of F region ionospheric variability, how propagation works on the new 630 and 2200 m bands, the Personal Space Weather Station, and more. Hamvention will be held May 17-19, 2019 at the Greene County Fairgrounds in Xenia, Ohio.
Plain Language Summary: Radio communications using the high‐frequency (HF) bands (3–30 MHz) is important for emergency communications because it is the only form of electronic communications that can travel over the horizon without relying on man‐made infrastructure such as the Internet, satellite systems, or phone networks. This is possible because HF rays can be bent back to Earth by the ionosphere, an electrically charged layer of the upper atmosphere. Space weather events such as X‐ray flares from the Sun and geomagnetic storms can alter the ionosphere to disrupt these communications. During September 2017, a significant number of solar flares and geomagnetic activity occurred. Simultaneously, major hurricanes, including Hurricane Irma and Hurricane Jose, caused situations in the Caribbean region requiring the use of emergency HF communications, often provided by ham (amateur) radio operators. This paper shows the impacts of these space weather disturbances on HF communications as observed by multiple ham radio monitoring systems.
This week, many HamSCI members are presenting their research at the American Geophysical Union (AGU) Fall Meeting in Washington, D.C. The AGU Fall meeting is one of the largest geoscience meetings in the world, and consists of about 24,000 attendees. The scientific program includes sessions pertaining to all areas of geophysics, including space weather, the solar wind, auroral activity, the ionosphere, and the neutral atmosphere. Below is a list of selected presentations and sessions being given by HamSCI members, or of general interest to ham radio operators. The complete scientific program is available here.
HamSCI will again be at the Dayton Hamvention, this year as part of the new Ham Radio 2.0: Innovation and Discovery area sponsored by the Yasme Foundation. Come visit the HamSCI Booth and Forum to learn about projects on the cutting of ham radio science and engineering research, including initial science results of the Solar Eclipse QSO Party (SEQP), the status of the Arecibo Observatory, the latest in understanding the causes of 6 meter sporadic E propagation, and how an inexpensive software defined radar for ionospheric studies works. Hamvention will be held May 18-20, 2018 at the Greene County Fairgrounds in Xenia, Ohio.
The 2018 HamSCI Workshop held at the New Jersey Institute of Technology (NJIT) February 23-24, 2018 brought together hams and space scientists from across the United States, Canada, and Great Britain. With over 60 people in attendance, presentations included results from the 2017 Great American Eclipse, ideas for a personal space weather station, and other amateur radio-space science experiments and projects.
Registration for the 2018 HamSCI Workshop is now open! The workshop will be held February 23-24, 2018 at the New Jersey Institute of Technology in Newark, NJ and seeks to bring together the amateur radio community and professional scientists. Anyone interested in this workshop is invited to join. This year, the workshop will focus on results of the 2017 Great American Eclipse ham radio ionospheric experiments (including SEQP results) and the development of a Personal Space Weather station.
The Yasme Foundation announced this past week that Nathaniel Frissell, W2NAF and Magda Moses, KM4EGE are winners of the 2017 Excellence Award for their role in starting HamSCI and organizing and promoting the Solar Eclipse QSO Party. From Yasme's Website, "The Yasme Excellence Awards are presented to individuals who through their own service, creativity, effort and dedication have made a significant contribution to amateur radio. The contribution may be in recognition of technical, operating or organizational achievement as all three are necessary for amateur radio to grow and prosper. These awards shall be given from time to time as the board feels appropriate."
