This is probably really easy question but I am just learning this stuff so dont laugh. but...
What earth longitude degree line directly faces and lines up center to Vernal Equinox vector? I am guessing the prime meridian 0 degrees longitude on earth lines up with Vernal Equinox every year which is 0 hour on the celestial sphere? But this is a guess. My readings on the web so far kind of skip that connection and explanation possibly infering but not confirming it for me.
or I could just be totally off.
thanks
