The aurora may be "beyond the curvature" of the earth. Additionally, they can be subtle. When lacking extreme brightness, they could be "unseeable" or missed or lost in "light pollution" to a viewer at moderate latitude. Certainly when a large magnetic storm is in progress, viewing latitude is more favorable to the viewer. Just such a large event on the sun in 1994 put observers at 47 degrees south latitude in a position to watch things. Wow! What a show that must have been! Got a link for ya if'n ya wan it.

∙ 13y agoThe aurorae are cause by high energy charged particles interacting with Earth's ionosphere. However due to the shape of the Earth's magnetic field, these particles are deflected toward the north and south poles, hence the aurorae are much brighter and more frequent the closer to the magnetic poles you get. Aurora Borealis is a specific term meaning 'Aroura in the northen hemisphere'. To specify southern aurora the term Aurora Australis is used.
Together they are known as 'aurora' the plural being 'aurorae'
_____________________________
Auroras occur when charged particles from the Sun interact with the ionosphere of the Earth. This TYPICALLY happens only at fairly high latitudes, but during solar storms, auroras are often visible in the mid-latitudes as well. The northern tier of states in the USA often see auroras, and during one freakish solar storm, they were visible as far south as Florida!

What is the minimum percent of the moon that needs to be illuminated in order for the phase to be called gibbous?
A "gibbous" Moon has between 51% and 99% of the illuminated side of the Moon visible from Earth. Just to be precise; the Moon is always 50% illuminated. The Moon is a rocky ball, half in sunlight and half in darkness. As the Moon orbits the Earth, the same face of the Moon is always visible. From the Earth, we see "phases" of the Moon as the Moon orbits the Earth. At the new moon phase, the illuminated half of the Moon is the "far side" of the Moon; at the full, the illuminated half is the "near side".
What time of the year is the Milky Way visible?
Every star you see is in the Milky Way, so you can say it is visible throughout the year. A particular line that looks like a trail or a sort of milky way goes through the night sky and can also be seen all year round in different constellations.
When the Sun and Moon are out at the same time is there no Sun and Moon out on the other side of the earth?
they are always out at the same time so yes but it is scince we are tilted they can also see it. _________________________________ Except at the full Moon, there is always a period at night when the Moon is not visible; either it has already set, or has not yet risen. At the new phase of the Moon, the Sun and Moon are pretty close in the sky, and the Moon isn't visible at all during the night.
Why do tornadoes almost always start in empty fields?
Tornadoes are most common in temperate grassland areas such as the Great Plains due to climatic factors. Such regions contain large areas of open fields.
What are the climate zones in the US?
The three major climate zones on the Earth are the polar, temperate, and tropical zones. Temperatures in these three climate zones are determined mainly by the location, or latitude, of the zone. polar- has the coldest with temperatures almost always below freezing. The Mainland US is temperate, Most of Hawaii is tropical, and Northern Alaska is polar.
