IARU Region 1 President Expresses Concern Regarding Spectrum Challenges in
Europe: International Amateur Radio Union Region 1 (IARU R1) President Don
Beattie, G3BJ, told an audience at Ham Radio 2017 (Friedrichshafen) that he is
"deeply concerned about our ability to maintain a usable radio spectrum in some
 parts of suburban Europe." Beattie said that Amateur Radio spectrum
allocations are of little value if they are "made unusable by the presence of
multiple sources of interference -- be it electrical interference or intruders
in the amateur bands." Beattie said the IARU "is deeply involved in the work of
 the international standards organizations, arguing for common sense in the
setting of emission standards for electrical and electronic devices." He cited
solar photovoltaic arrays, wind generators, digital devices, VDSL+ and wireless
 power transfer technology as areas of current concern. "Some would say that
even with the work we are involved in on standards, much of the radio spectrum
is becoming unusable in the suburban environment," Beattie said, "and I have
sympathy with this view." -- Thanks to Southgate Amateur Radio News

declined by just 1.7 to 26.6, although July 18 and 19 saw no sunspots. Average
daily solar flux was 85.9, down 1.1 from the previous week.

The average planetary A index rose 3.9 points to 13, the average mid-latitude A
 index rose from 9.6 to 10.9. A coronal mass ejection (CME) on July 16 struck
at 0545 UTC, driving the planetary A index to 41, and 27 the following day.

90 on July 29-August 11; 85 on August 12-13; 80 on August 14; 74 on August

15 and 12 on August 17-18; 5 on August 19-31, and 25 and 10 on September 1-2.

David Moore called my attention to an excellent New York Times article,
"Unlocking Mysteries in the Sun's 11-Year Cycle."

Sunspot numbers for July 13 through 19, 2017 were 55, 58, 34, 26, 13, 0, and 0,
 with a mean of 26.6. The 10.7-centimeter flux was 92.3, 93.9, 91.6, 86.5,
85.6, 78.2, and 73.1, with a mean of 85.9. Estimated planetary A indices were
