The Deep Space Climate Observatory (DSCOVR) is scheduled to begin operations this summer giving early warning of solar storms. It was launched from Cape Canaveral on February 11, 2015. Essentially, it will replace the Advanced Composition Explorer (ACE) satellite (in operation at L1 since the late 1990s) with upgraded measurement capabilities.

An EOS Earth & Space Science News on-line article by Delores Knipp and Douglas Biesecker describes the mission:
