Default Earth is entering a stream of debris from an unknown comet

Space Weather News for June 4, 2015
http://spaceweather.com

Earth is entering a stream of debris from an unknown comet, and this
is causing one of the most intense meteor showers of the year.
Ironically, most sky watchers won't notice because the shower peaks
in broad daylight. We only know it's happening because a radar in
Canada is picking up echoes from meteoroids streaking through the
blue sky overhead. Astronomers call these meteors "Arietids" because
they emerge from the constellation Aries not far from the June sun.
For observing tips on how you might be able to see earthgrazing
Arietids just before sunrise in the mornings ahead, visit

It is a real pity that observers can't get their act together and consider observations in a more productive way than the astrological descriptions in that paragraph.

To appreciate the motion of the Earth and those of the inner planets it is crucial to set aside the older astrological descriptions of the 'June Sun' and the apparent passage of the Sun through the constellations and adopt the more productive line-of-sight observation where the stars appear to move behind the central Sun in sequence -

All that is happening is the Earth is moving through space therefore the only valid use of the apparent motion of the stars is the one using the orbital motion of the Earth and not daily circumpolar motion and its celestial sphere connotations.

The debris stream is meant to give the observer the impression of the Earth as a vehicle moving through space like a car passing through a local rain shower but the celestial sphere descriptions block this productive view.
