DSCOVR
Sits between the Earth and the Sun measuring the solar wind before it arrives, which is where the warnings of a geomagnetic storm come from - about fifteen to sixty minutes of notice for the power grids and the satellite operators. From the same place its camera photographs the whole sunlit face of the Earth several times a day.

Path
A drifting loop about L1, the balance point 1.5 million km sunward of the Earth. It does not close on itself and it slides off, so it is nudged back every few months.
Along the way
- Arrived at L1
- First photograph of the whole sunlit Earth from here
