Solar flares are large explosions from the surface of the sun that emit intense bursts of electromagnetic radiation. The intensity of the explosion determines what classification the flare belongs to. The most powerful are X-class flares, followed by M-, C- and B-class; A-class flares are th...

Observations of track-rich grains found in deep lunar cores and meteorite interiors are discussed which demonstrate the presence of solar flare activity for at least the past 4 billion years, and the similarity of track density profiles from various lunar and meteoritic samples with those in a ...
While space weather ultimately originates on the sun, the term solar storm refers to occurrences on, or near, our own planet, when material tossed out by the sun reaches us. There are two distinct types of solar storm: Geomagnetic storms and solar radiation storms. A CME erupted on Jan....
This describes the same situation that we are currently in with the CONVID-19 pandemic – the same prevention strategies are being used while a search for a vaccine is currently underway. You would think that having gone through this in 1918 our elected officials would take this more seriously...
It describes an important cycle of relationship between the Sun, Earth, and another planet; a period centered on the planet s perigee (closest approach to Earth). The table below shows the Mercury Max cycles for 2022-2023. In particular, note the first line in the table, which details the...
somewhat mockingly describes the theory to encompass “aardvarks, baseball, and galaxies; or grilled cheeses, commandos, and Lake Michigan.” For OOO, your skin cells are objects, and so are you, and so is the population of the nation you live in, and so is the very idea of ...
