The blinding of the #Byzantine Emperor Constantine VI in #Constantinople in August 797 CE and his overthrow by his mother Eirene was used as legitimation for the #coronation of the Frankish King #Charlemagne as emperor of the Romans on 25 December, 800. (2/9)

In #Byzantine sources, Constantine VI´s #blinding was linked with a spectacular #celestialmanifestation of divine disapproval: “The #sun was darkened for seventeen days and did not emit its rays so that ships lost course and drifted about.” (3/9)

The Sun spewed out two consecutive coronal mass ejections on August 14-15, giving rise to a 'Cannibal CME'.
The scarier part? It's heading towards the Earth this week & could spark strong geomagnetic storms on Aug 18!

A cloud of dark plasma erupted on the solar surface on Aug 14, launching a #CME that could side sweep the Earth's magnetic field.
Then, on Aug 15, an exploding magnetic filament launched another CME right at its tail.
Then, on Aug 15, an exploding magnetic filament launched another CME right at its tail.
This could be a Cannibal CME event where the second CME might overtake and gobble up the first, creating a mish-mash of the two.
Cannibal CMEs contain tangled magnetic fields and compressed plasmas that can spark strong geomagnetic storms.

Eyección de #MasaCoronal e intensa #Llamarada Solar☀️clase X1 registrada por SDO🛰en Oct.28. Radiación de #Llamarada causó algunos problemas en señales de radio en Sudamérica. Partículas cargadas de Eyección arribarán a Polos mañana: #Auroras pronosticadas!blogs.nasa.gov/solarcycle25/2…
Las llamaradas, eyecciones de #masacoronal, y la emisión de #vientosolar son parte de la normal actividad solar transiente.
