There will be total eclipse of the sun over Antarctica on December 4, but the HamSCI citizen science group is asking amateurs around the world to help collect data on changes it causes in radio propagation. According to the ARRL Letter, it is expected that the shadow of the moon crossing over Antarctica will generate traveling ionospheric disturbances, or TIDs, that will in turn affect propagation.
Hams and shortwave listeners with HF radios connected to computers are asked to collect Doppler-shift data from WWV or other time-and-frequency standard stations between December 1 and December 10 and report the data to an internet site. Complete details and additional information on the Antarctic Eclipse Festival are available at <www.hamsci.org/festivals>.
