COMMENT: A small sunspot group (Catania number 23) emerged in the
northern solar hemisphere. We do not expect it to produce any noticeable
flaring activity. A small low-latitude coronal hole in the northern
hemisphere reached the solar central meridian yesterday. A fast solar
wind stream from this coronal hole may arrive to the Earth on November
7. Due to a small size of the coronal hole, we do not expect any
significant geomagnetic disturbance. The solar wind speed at Earth is
currently low (around 300 km/s) and the interplanetary magnetic field
magnitude is average (around 5 nT). We thus do not expect any
geomagnetic disturbance.

TODAY'S ESTIMATED ISN  : 008, BASED ON 07 STATIONS.
