The solar disk is currently spotless, solar activity is expected to be very low on UT day 18 October. The solar wind speed is currently light but expected to increase to moderately elevated levels late today due to coronal effects. Geomagnetic activity is expected to increase to active levels with a slight chance of minor storm periods later in the UT day. Normal to fair HF propagation conditions are expected with no shortwave fadeouts.
