Operating an aurora - Ham Radio Engineering
2012年7月15日 · Excellent video on operation during a radio aurora. Here are some broad ideas about operating during an aurora. These are taken from many web sources. Operating an aurora. Be ready. Auroras don’t last long. Monitor space weather for Kp going high to indicate a geomagnetic storm.
Propagation via an aurora - Ham Radio Engineering
2024年5月12日 · Propagation via an aurora. This then illustrates how a radio amateur would approach communications via an aurora. An estimate of the strength of the aurora and hence how far south the radio auroral oval has sunk leads speculation about likely beam angles.

2009年7月1日 · Auroras are usually observed as coloured lights or a glow coming from the upper atmosphere, and appear to be associated with instability in the geomagnetic field of the Earth. The glow is caused by solar flares colliding with atoms of Oxygen and Nitrogen in the upper atmosphere, causing ionsation of the atoms.

Radio auroras - Ham Radio Engineering
2024年10月7日 · Auroras overview. Auroras are caused by the interaction between the solar wind, the molecules in the upper atmosphere (ionosphere), and the interplanetary magnetic field (magnetosphere). This follows an ejection of high-energy helium and hydrogen ions and electrons from the Sun heading earthward as a solar wind.

In addition to creating a pretty light show (mostly in upper latitudes), ham radio signals scatter off of these particles and can greatly enhance propagation on the VHF and UHF ham radio bands. High levels of aurora can also make HF ham radio propagation via polar routes difficult.
Propagation: Aurora
Auroral activity is most likely around the equinoxes, but may happen at any time when the proper solar disturbances occur. Heavy auroral activity can also induce regular Es during the following day or two and at 27-day intervals coinciding with the rotation of the sun.
