Caution Light: The Anik E2 Solar Disruption And Its Effect On Telesat Canada
… Anik line. On January 20, 1994, a major solar storm knocked out communications on two Anik satellites. Anik E1 was recovered through a backup system within hours. However, Anik E2 was non-operational until June 31, 1994, when engineers used an innovative ground fix to regain control.</p> …

Low frequency plasma waves at Mars
… plasma waves produced in the interaction of the solar wind with the Martian ionosphere. Using the MAG/ER data, I identify the properties and physical origins of the waves in the magnetosheath, magnetic pileup region, and ionosphere. I find that the waves in the dayside magnetosheath are …

Characterization and Modeling of Solar Flare Effects in the Ionosphere Observed by HF Instruments
… frequency (HF, 3-30 MHz) radiowave propagation. Solar activities, such as solar flares, radiation storms, coronal mass ejections (CMEs), alter the state of the ionosphere, a phenomenon known as Sudden Ionospheric Disturbance (SID), that can severely disrupt HF radio communication links by …

Geomagnetically induced currents and their effect on power systems
… to power grids around the world. For example, solar storms that generate coronal mass ejections can induce a change in the Earth’s magnetic field. Geomagnetically induced current (GIC) then enters the power grid and causes unusual real and reactive power flows, voltage fluctuations, frequency …
