As Solar Cycle 25 begins, amateur radio operators look forward to the return of the exciting propagation conditions associated with solar maximum. The classic paradigm for solar cycle prediction is based on an 11-year sinusoidal pattern of sunspot numbers, with an official NASA-NOAA "consensus" prediction coming from a panel of experts evaluating an ensemble of different types of models. However, the underlying solar cycle mechanism is still not well understood and this consensus prediction can fall short. Scott McIntosh at the U.S. National Center of Atmospheric Research (NCAR) and his team have recently published a new method for predicting the time and amplitude of solar maximum, based on changes in the observed magnetic polarity in different regions of the sun. This new method predicts a stronger Solar Cycle 25 than the NASA-NOAA "consensus" prediction. HamSCI member Frank Howell K4FMH teams up with Dr. McIntosh to review this new methodology and its potential impacts on how we think about solar cycle predictions in a two-part article series currently featured on the cover of RSGB's RadCom magazine. More information can also be found at Frank's blog.
"Our sense of sound can be a powerful tool in exploring and analysing data collected from satellites. But what is the best way to make this data audible? Space science researchers at Imperial College London asked for your input on which methods of making the sounds of near-Earth space audible produce the best results. We’re pleased to announce that the results of this survey have now been published in Frontiers in Astronomy and Space Sciences. The feedback was invaluable, providing clear recommendations on which methods were best. These are now being used by space scientists around the world to improve their science communication, public engagement, and citizen science. Thank you!"
HamSCI played a major role at the 2022 Dayton Hamvention, which was held in Xenia, Ohio May 20-22, 2022 at the Green County Fairgrounds The Dayton Hamvention is sponsored by the Dayton Amateur Radio Association and is the world's largest ham radio gathering, with over 32,000 attendees at the 2019 Hamvention. The Hamvention is an extremely important event for engaging with the amateur radio community, sharing ideas, developing collaborations, and sharing scientific results. This year, HamSCI hosted a booth, gave presentations in the Ham Radio 2.0 area, and hosted a forum. Support for the 2022 HamSCI Hamvention activities comes from The University of Scranton, the Yasme Foundation, TAPR, the National Science Foundation, NASA, and volunteers like you. This year, HamSCI will again host a booth in building 5 next TAPR, host booth talks in the Ham Radio 2.0 area, run demos, and the host HamSCI Forum.
