Propagation Summary
The Geomagnetic field was disturbed on March 1 – 2, quiet to active on March 3 – 6. Mostly quiet on March 7, and quiet on March 8 – 9.
The Boulder A, and K indices were at their lowest on March 7 to 11. Solar flux was at 72 on March 5 to 7. Calm conditions prevailed until 15-16 March, a slight increase in solar wind speed was observed. This was likely due to a coronal hole high speed stream (CH HSS).
The geomagnetic field responded with isolated unsettled periods on 15 and 16 March. The greater solar flux was at normal to moderate levels with high levels observed on 13-15 March.
Geomagnetic field activity ranged from quiet to unsettled levels. Solar wind speed was at nominal levels through most of the period. On 15-16 March, a slight increase in solar wind speed was observed. This was likely due to a positive polarity coronal hole high speed stream (CH HSS). . The geomagnetic field responded with isolated unsettled periods on 15 and 16 March.
The greater solar flux is expected to be at normal to moderate levels with high levels likely on 24 March and again from 29 March - 11 April due to recurrent CHHSS activity.
Geomagnetic field activity is expected to be at unsettled to active levels on 28 March - 06 April. G1 (Minor) geomagnetic storm levels are likely on 23, 28-31 March and 02 April while G2 (Moderate) geomagnetic storm levels are likely on 28-29 March due to recurrent CH HSS effects. BDXC member Martin J Reynolds has been conducting experiments with DRM with reception of R. Romania Int. on 7350 kHz at 18.00-19.00 UTC daily and this should also be interesting for comparison with analogue reception. The next propagation report will be in June.

Forecast of Solar and
Geomagnetic Activity up to 15 April 2017
Solar activity is expected to be at very low levels for the forecast period. The greater solar flux is expected to be at normal to moderate levels with high levels likely on 24 March and again from 29 March - 11 April due to recurrent CHHSS activity.
Geomagnetic field activity is expected to be at unsettled to active levels on 28 March - 06 April. G1 (Minor) geomagnetic storm levels are likely on 23, 28-31 March and 02 April while G2 (Moderate) geomagnetic storm levels are likely on 28-29 March due to recurrent CH HSS effects.
