High-latitude sky watchers should be alert for auroras this week

Space Weather News for April 20, 2015

High-latitude sky watchers should be alert for auroras this week when
a solar wind stream and a faint CME are expected to hit Earth's
magnetic field in quick succession. NOAA forecasters estimate a 45%
to 65% chance of polar geomagnetic storms on April 21-22.

At the same time, Earth will be passing through a stream of debris
from Comet Thatcher, source of the annual Lyrid meteor shower. Sky
watchers are already seeing a smattering of late-night fireballs as
Earth approaches the diffuse core of the debris stream. Meteor rates
are expected to crest on April 22-23 with as many as 20 Lyrids per
hour.

Tell me Sam ,as possibly the one person left in saa that I would care to respond to, what do you think causes the seasons just by look at the article in that website ? -

If you stood in front of your students and told them that there are two daylight/darkness cycles to consider with a slight shift of attention towards the year long polar day/night cycle you would be half way there to teaching them that the Earth has dual surface rotations - all planets do.

The only explanations presently are the cringing 'earth tilts towards and away from the sun' in lieu of not accepting the necessary surface rotation where the North/South poles are seen to move parallel to the orbital plane.

Truly remarkable !.
