I discovered that one, 'bout 12 years ago, when I was posting all those weather reports here, showing Solar wind speads and densities, CMEs, the satus of the manetosphere and all. a lot of my data came straight out of SOHO, out at EL-1, where the satellites (I understand there are a few of them) obit the null region of the lagrange, while focusing cameras on the Sun.

It will doubtless carry fuel to stableize, and there may be need for occasional adjustments, but not a lot. My understanding is that an object cannot occupy the actual lagrange point, but can slowly orbit it. And I believe lagranges 2 and 5 are negative, while 1, 3 and 4 are positive.

Gaia will be our first outpost at EL-2, so watching her might prove interesting.

Well, again, gotta log out.

Cheers.
