"NOAA warns of dangerous CME strike and potential geomagnetic storm"

The National Oceanic and Atmospheric Administration (NOAA) has issued a warning for a dangerous solar storm today, May 16, which is expected to cause a G1-class geomagnetic storm. The solar storm can disrupt wireless communications and GPS services, causing trouble for airlines, mariners, ham radio controllers, and drone operators. The coronal mass ejection (CME) is likely to strike the Earth in a few hours' time as per the NOAA models. NASA's Solar Dynamics Observatory (SDO) carries a full suite of instruments to observe the Sun and has been doing so since 2010.
