Propagation News – 9 December 2018

We had a new sunspot group, Region 2729, appear this week, although it is a member of the weakening Solar Cycle 24. The region formed fairly quickly in the sun’s southwest quadrant and at the time of writing was producing only very minor B-Class solar flares. It is unlikely to do too much for the solar flux index though, which …

The K7RA Solar Update

After nine days with no sunspots, sunspot group 2729 emerged on December 5. The sunspot number on that date was 16. Average daily solar flux for the week was 68.9, unchanged from last week. On Thursday, December 6 the appearance of 2729 continued, with a sunspot number of 17 and the sunspot area increasing from 30 to 50 millionths of …

Propagation News – 2 December 2018

The CQ Worldwide CW contest last weekend showed that you can work DX with zero sunspots. Reports show that stations as far west as Arizona and California, plus the Caribbean, were workable from the UK on 20 metres, plus there were reports of some limited F2-layer openings on 10 metres. Chris, G0DWV even reported an afternoon greyline opening to Japan …

The K7RA Solar Update

At 2335 UTC on November 28 the Australian Space Forecast Centre issued a geomagnetic disturbance warning for December 1. “The effect of a high speed solar wind stream from a large and recurrent coronal hole may raise the geomagnetic activity to minor storm levels on December 1 and 2.” Sunspots appeared on only two days over the past reporting week, …

The K7RA Solar Update

We saw sunspots return recently, but only for a week, November 13-19. From last week’s bulletin, average daily sunspot number rose from 3.1 to 9.4, while average daily solar flux rose from 68.5 to 70.8. That week-long sunspot appearance was sunspot number 2727, but last weekend another smaller sunspot appeared briefly, so brief that it was not assigned a number, …

Propagation News – 25 November 2018

Last week saw relatively quiet geomagnetic conditions, thanks to a reduction in coronal hole activity. The Kp index never got higher than three, and was usually between zero and two for most of the week. We had a solar flux index high of 72 and a low of 69, which is in keeping with this point in the solar cycle. …
