A New Journey Around (and Around) the Sun

by Daniele Telloni, Francesco Valentini and Raffaele Marino 25 February 202231 January 2023

The Solar Orbiter just completed its commissioning phase while en route to the Sun. It has already provided valuable looks at solar campfires and Venus’s magnetic fields, and it promises much more.

Example of how, given the presence of aurora, an over-the-horizon radar based in Scotland might be used to track an aircraft at 10 km altitude in a region to the north.

Can Aurora Enhance Radar Monitoring of Arctic Aviation?

by Michael A. Hapgood 2 February 202215 March 2022

Enhanced E-region ionization produced by the aurora can be used to reflect signals from over-the-horizon radars and thus enable those radars to better monitor aviation in Arctic regions.

Observing the Sun via Soil Moisture Measurements

by Michael A. Hapgood 31 March 202113 October 2021

Solar radio bursts are background noise for satellite-based radio observations that monitor soil moisture, so, with appropriate processing, those observations can provide data on radio bursts.
