The HamSCI[1] Antarctic Eclipse Festival in December is seeking amateur radio participation. As the shadow of the moon passes across Antarctica on December 4, it will generate traveling ionospheric disturbances that will, in turn, affect radio propagation. The unusual geometry of this year's eclipses will give researchers an opportunity to investigate complicated ionospheric dynamics over the poles as the long daytime of polar summer is briefly interrupted by the eclipse.

During this and other HamSCI eclipse festivals, hams and citizen-scientists are asked to collect Doppler-shift data from time-standard stations, such as WWV[2]. All that's needed is an HF radio connected to a computer. A GPS-disciplined oscillator is helpful for collecting data, but it is not required. Data collection will run from December 1 through December 10, and the results will be made available for scientific analysis.

All radio amateurs and shortwave listeners are invited to join in, even those located far from the path of totality. In 2020, more than 100 individuals from 45 countries took part in eclipse festivals.The instructions are available in multiple languages.

HamSCI is an initiative of ham radio operators and geospace scientists dedicated to advancing scientific research and understanding through amateur radio activities. Eclipse festivals are pilot campaigns for the Personal Space Weather Station (PSWS), HamSCI's flagship project. The PSWS team seeks to develop a global network of citizen-science stations. Participants monitor the geospace environment to deepen scientific understanding and enhance the radio art.
