I was able to work JE1 in Japan and JA1NUT on 20 meter CW around 2220Z and small portable/mobile stations from National Parks were mostly near normal signal levels very workable. Despite this, paths from east through south to west were not that bad up to 15 meters. “Starting Monday before the contest, the K index was 4 or higher almost all week and storm levels moderate or stronger. Jeff, N8II,reports again this week from West Virginia, this time about last week’s CQ World-Wide SSB DX Contest. Ran across this from Discover Magazine about solar seismology: I called CQ while beaming to the north, but no takers.”

There was a brief auroral opening on the October 26 around 2200 Z. “Six meters has been pretty quiet here with a brief Es opening on October 25 at 1754 Z. Richard Ferry, K2KA of Westford, Massachusetts sent this a week ago, just after I submitted last week’s bulletin to Newington, on October 28: Regular contributor David Moore sent this, about recent aurora: Jimmy Mahuron, K9JWJ, submitted this reference to construction of a VLF receiver for detecting Sudden Ionospheric Disturbances.

Indeed, I see their weekly Saturday schedule listed under Events on the NPOTA web site. With separate 1.5 kW transmitters and gain antennas for each frequency, we get out pretty well - propagation permitting! We're on the air each Saturday and Sunday from 1200 to about 1700 Pacific time.” “I hope/assume you have bagged K6KPH, one of the only permanent stations in a national park (Point Reyes National Seashore). Richard Dillman, W6AWO, of Point Reyes Station, California saw the reference to the ARRL National Parks on the Air activity by N8II in last week’s bulletin, and wrote: Parenthesis means lower probability of activity enhancement.” Quiet to active on November 12-13, 20, 24Īctive to disturbed on November 21-23, 25-26Īmplifications of the solar wind from coronal holes are expected: “Geomagnetic activity forecast for the period November 4-November 30, 2016 Petr Kolman, OK1MGW, of the Czech Propagation Interest Group sent us this on October 3. Over the same three-month period in 2015 the average was 64.5, and in 2014 it was 108.4. Looking at our three-month moving average of sunspot numbers, the average sunspot value for August 1 through October 31 was 39. Predicted planetary A index is 10 and 8 on November 4-5, 5 on November 6-10, then 10, 15, 18, 10 and 8 on November 11-15, 5 on November 16-18, then 8, 15, 54, 42 and 24 on November 19-23, then 18, 22, 18, 15 and 12 on November 24-28, then 8 on November 29 through December 1, then 5 and 8 on December 2-3, and 5 on December 4-7. Geomagnetic indicators were slightly lower, with average daily planetary A index declining from 20.3 to 18.1, and mid-latitude A index from 16.7 to 13.4. Average daily sunspot number for the week was 9.1, down from 18.7 over the previous seven days.Īverage daily solar flux rose, but only slightly from 76.9 to 77.5. Prior to the past week, in recent memory only October 1 had no sunspots either. Over the past reporting week (October 27 through November 2) we saw two days with no sunspots, October 28 and November 2. At 2347 UTC on November 3, Australia’s Space Weather Services issued a geomagnetic disturbance warning: “Expect Unsettled to Active conditions with periods of Minor Storm levels in the Australian region for the next UT day, 4 November, if a small coronal hole in the Southern hemisphere becomes geoeffective.”īut as of November 3, the prediction from NOAA/USAF for planetary A index for November 4 and 5 is only 10 and 8.
