Hello,
in heliocentric coordinates the longitude of the Earth on april 15, 2010 is 204.91°... well I know that the longitude in ecliptic system (centered on the Earth ) is measured from the vernal equinox... if i started measure from V.E. in heliocentric system too I would find the Earth in Autumn!
So I'm wondering...is the longitude measured from libra point?
