NOAA AR 1907 produced the only C-flare of yesterday November 30. We forecast a probability for C-flares slightly above 50%. A partial halo CME was detected by CACTus. The CME appeared in the field of view of SOHO/LASCO C2 around 19:00, November 29. There was no clear on disk signature of the eruption. We can assume that the CME is back sided. The solar wind speed increased to 350 km/s. The total interplanetary magnetic field (IMF) shows also an increase since yesterday. The solar wind structure passing near the L1 point can be possibly linked to the northern coronal hole that passed the central meridian on November 24. The plasma pressure although was not strong enough to cause a geomagnetic disturbance. Similar for the z-component of the IMF which was not strongly negative. The planetary Kp stayed below 4. We expect quiet geomagnetic conditions with K lower than 4.
