Ionospheric variability produces measurable effects in Doppler shift of HF (high-frequency, 3–30 MHz) skywave signals. These effects are straightforward to measure with low-cost equipment and are conducive to citizen science campaigns. The low-cost

Ionospheric variability due to atmospheric coupling produces measurable effects in Doppler shift of HF (high frequency, 3–30 MHz) skywave signals. These effects are straightforward to measure with low-cost equipment and are conducive to citizen sci

A model is proposed which furnishes a non-black hole-based explanation of the Galactic center compact source and similar sources at the cores of M81 and M82. The model demonstrates that a normal young pulsar is sufficient to power each of these sourc
