(meteorobs) Re: The Exploding Lunar Eclipse

[Robert Lunsford]

Bruce and All,

Helions are outbound from the inner solar system while antihelions are 
inbound from the outer solar system. The helion radiant lies on the ecliptic 
approximately fifteen degrees east of the sun, so it sets an hour after the 
sun (very difficult to see!). The antihelion lies on the ecliptic fifteen 
degrees east of the opposition point so it rises as the helion radiant sets.

Clear Skies!

Bob

    Interesting story on NASA Science News. I assume "Helions" are the 
opposite of "Anthelions", and would be (almost?) impossible to observe as 
meteors within our own atmosphere.

NASA Science News for August 27, 2007
On Tuesday morning, Aug. 28th, a team of astronomers and engineers at the 
Marshall Space Flight Center will attempt something never done before--to 
observe meteoroids hitting the Moon and exploding during a lunar eclipse. 
This will allow them to explore an elusive and mysterious population of 
"Helion" meteoroids coming from the direction of the sun.
