Not a whole lot happening on the Sun today. Space weather is fairly quiet but we could see the passage of a minor coronal mass ejection within the next 24 hours which could stir up to minor G1 geomagnetic storm conditions according to the NOAA SWPC. But that is not the main space weather story of today. It is SpaceX which steals the headlines today. A geomagnetic storm is blamed by the company for the loss of 40 (out of 49) Starlink satellites launched last Thursday.
