A solar eclipse will occur across a broad swatch of the continental United States on 21 August 2017.  Although Hawaii will have only a partial eclipse, many radio amateurs will join their colleagues that day to study how this phenomenon will affect long distance communication between Hawaii and the U.S. mainland.

Stacy Hollbroook (KH6OWL), the ARRL PIO for Oahu, sent me this article about the eclipse:

North American / Hawaii Eclipse and Amateur Radio


Saturday, June 10, 2017. Oahu, HI


The first total solar eclipse in the continental United States in 38 years will happen Aug. 21, 2017, and it’s not too soon to learn about it and to begin making your plans and Amateur Radio Operators will help observe the Solar Eclipse in North America and provide date to scientist.


The eclipse will cross the United States from Oregon to South Carolina in 94 minutes. The states in the path are Oregon, Idaho, Wyoming, Nebraska, Missouri, Illinois, Kentucky, Tennessee, North Carolina, Georgia and South Carolina.

The eclipse will not be total in Hawaii so you must always eye protection to view the eclipse if you are in Hawaii! Oahu will have about 27% coverage and early morning.

Amateur Radio Operators across North America and Hawaii will use the ionosphere to report how the solar eclipse will impact their ability to talk across vast distances by using networks such as the Reverse Beacon Network to collect data and using amateur radio data to complement data from other sources.


Previous research shows that the shadow of the eclipse will impact the ionospheric state, but has not adequately characterized or explained the temporal and spatial extent of the resulting ionospheric effects. HamSCI is inviting the amateur radio community to contribute to a large scale experiment by participating in an Eclipse QSO party and further developing automatic observation networks such as the Reverse Beacon Network. Data resulting from these activities will be combined with observations from existing ionospheric monitoring networks in an effort to characterize and understand the ionospheric temporal and spatial effects caused by a total solar eclipse.
