Bulletin

The Sun did not produce any C flares in the past 24 hours. There is a 50% chance of C flares within the next 24 hours. In the past 24 hours, the solar wind speed detected by ACE increased from 320 to 470 km/s and is currently around 420 km/s, while the magnitude of the Interplanetary Magnetic Field varied between 4 and 15 nT and is currently around 6 nT. Over the past 24 hours, geomagnetic conditions have been quiet to active (K Dourbes between 1 and 4; NOAA Kp between 1 and 3). Quiet to unsettled (K Dourbes < 4) conditions are expected on November 29 and 30. Active (K Dourbes = 4) to minor storm conditions (K Dourbes = 5) are possible on December 1, due to the expected arrival of a coronal hole high speed stream.

Today's estimated international sunspot number (ISN): 050, based on 06 stations.
