"NOAA’s first space weather satellite, DSCOVR, has completed instrument
validation and will go operational on July 27, when it will take over
the role of monitoring potentially damaging space weather storms as they
approach Earth. [...]

Data from DSCOVR, which will be available to the public in real-time
online, will allow forecasters to provide space weather warnings and
alerts up to an hour before a surge of particles and magnetic field
generated by solar storms hit Earth."
