2017 Total Solar Eclipse

Map of US Eclipses from 2017-2052

On 21 August 2017, a total solar eclipse caused the shadow of the moon to traverse the United States from Oregon to South Carolina in just over 90 minutes. Although the ionospheric effects of solar eclipses have been studied for over 50 years, many unanswered questions remain. HamSCI invited amateur radio operators to participate in a large-scale experiment which characterized the ionospheric response to the total solar eclipse and targeted open science questions.

Hundreds of ham radio operators helped out by getting on the air with the Solar Eclipse QSO Party, a contest-like operating event designed to generate data for studying the eclipse. Other HamSCI experiments included making HF Frequency Measurements, recording HF spectra, setting up a Reverse Beacon Network Receiver, particpating in VLF/LF receiving experiements, and listening to AM broadcast stations. See our Eclipse Get Involved for more information.

The annual HamSCI Workshop will be held virtually this year March 19-20, 2021 using Zoom hosted by The University of Scranton and sponsored by the National Science Foundation. The primary objective of the HamSCI workshop is to bring together the amateur radio community and professional scientists. The theme of the 2021 HamSCI Workshop is midlatitude ionospheric science. We welcome submissions related to development of the Personal Space Weather Station, ionospheric science, atmospheric science, radio science, space weather, radio astronomy, and any science topic that can be appropriately related to the amateur radio hobby. We especially encourage subimissions related to this year's meeting theme of midlatitude ionospheric physics, but will also accept abstracts outside of this theme and otherwise appropriate. To submit an abstract, please fill out the on the HamSCI Workshop 2021 page at http://hamsci.org/hamsci2021.

Save the dates! The next HamSCI workshop will be held virtually March 19-20, 2021. The HamSCI workshop is an annual meeting to share scientific and engineering ideas and results related to amateur radio, radio propagation, and radio science, as well as foster collaborations between the amateur radio and professional space science and space weather communities. The 2021 workshop will serve as both a team meeting for the Personal Space Weather Station project, as well as a forum for presentations on topics relevant to the HamSCI mission. The format will be similar to virtual March 2020 HamSCI workshop. Thanks to support from the National Science Foundation and The University of Scranton, the cost of this workshop is free. Abstract will be due February 15th. Information regarding abstract submission and other workshop details will be forthcoming. Please join the HamSCI Google Group to stay up-to-date on the latest information.

The IEEE Transactions on Antennas and Propagation have recently accepted new research by Chris Deacon G4IFX, Ben Witvliet PE5B, Simon Steendam, and Cathryn Mitchell M0IBG entitled Rapid and Accurate Measurement of Polarization and Fading of Weak VHF Signals Obliquely Reflected from Sporadic-E LayersThis research uses signals produced by a network of 6 meter amateur radio beacons across Europe.
