> DSCOVR (Deep Space Climate Observatory) is an American space weather station that monitors changes in the solar wind, providing space weather alerts and forecasts for geomagnetic storms that could disrupt power grids, satellites, telecommunications, aviation and GPS.

> DSCOVR can warn forecasters 15 to 60 minutes before solar storms reach Earth.

How does one prepare these systems for a solar storm within 15-60 minutes?

I think you get a couple of days' advance notice, but don't know exactly when it will arrive until you get word from DSCOVR. Satellites can turn off radio receivers, astronauts can get in their shielded compartment. Maybe some power systems disconnect from the grid.

Land planes, stop (or don't start) surgeries, send first responder instructions, call loved ones

Launch the missiles.

Probably by making sure backups are ready to go and having people expecting it in case something does break? So if something goes wrong they're aware that a solar storm might've caused it rather than a localized issue.
