Bulletin

Only one single C1.9 flare erupted from the Sun, with NOAA active region (AR) 2434 as source region. NOAA AR 2436 remains the largest region on disc, but is decaying in complexity. Flaring activity at the C-level is expected. No Earth-directed CMEs were observed.

The solar wind speed was variable between 400 and 480 km/s, while the magnitude of the interplanetary magnetic field was relatively stable near 6 nT. Mainly quiet (K<3, at local level in Dourbes) and up to unsettled (K=3 at global NOAA Kp) geomagnetic conditions were observed. A glancing blow from the October 22 CME may arrive in the coming period, which may result in (at maximum) minor storm (K=5) conditions.

Today's estimated international sunspot number (ISN): 076, based on 07 stations.
