AuroracastUKTonight's Chance — 5%
Quiet tonight
Solar activity is low. We'll alert you if it changes.
Quiet — monitor Bz for changes
Solar wind comes from NOAA's satellites, which occasionally have short data gaps. This isn't a fault with the site — the reading updates automatically the moment NOAA's feed resumes, with nothing for you to do. Your Hp30 reading (from GFZ Potsdam) is unaffected. Why does this happen?
