On Monday 8 April 2024, a total solar eclipse gripped North America as radio amateurs worldwide looked on to see its effect on the ionosphere. This included RSGB Propagation Studies Committee (PSC) associate member Gwyn Griffiths, G3ZIL, who was interviewed by BBC news on the topic. The article, which was shared across the world, looked […]
Solar Cycle 25 is officially here
The Solar Cycle 25 Prediction Panel, an international group of experts co-sponsored by NASA and NOAA, announced that the solar minimum occurred in December 2019, marking the start of a new solar cycle. Because our Sun is so variable, it can take months after the fact to declare this event. Scientists use sunspots to track […]
Solar eclipse QSO party on Monday
On Monday a solar total eclipse will sweep across the USA and many radio experiments will be conducted, taking advantage of the expected anomalous propagation conditions. The August RadCom described the solar eclipse QSO party that will take place from 1400 to 2200UTC on Monday, 21 August 2017. Activity will be on several bands from […]
Solar information for January 2017
The January RadCom went to press before the following information was available to add to the Propagation page. Key: The figures represent approximate S-Meter readings, whilst the colours represent expected circuit reliability. Black equals low to very low probability, Blue equals good probability and Red equals a strong probability. No signal is expected when a […]
Amateur experiments for solar eclipse
On Friday 20 March 2015 a partial solar eclipse will be visible from the UK. The path of totality will pass north of the UK, but up to 89 percent of totality may be experienced, depending on where you live. As part of British Science Week, the RSGB has prepared a simple experiment using a […]
Eight days of solar flares on NASA video
NASA has released a video showing eight days of solar flares produced by the largest sunspot in the past two dozen years. Known as AR 2192, the video is a time lapse that shows its X-class flares in both visible and ultraviolet light using images taken by the Solar Dynamics Observatory Atmospheric Imaging Assembly Instrument.
