• 2 The ARRL Letter for August 24, 2017

    From mark lewis@1:3634/12.73 to all on Fri Aug 25 10:14:48 2017
    High-Speed Telegraphy Competition Set for September 8-12 in Hungary: The 14th High-Speed Telegraphy (HST) World Championship will take place September 8-12 in Esztergom, Hungary. The event's date was shifted this year to avoid conflicting with the International Amateur Radio Union Region 1 (IARU-R1) General Conference. The Hungarian Radio Amateur Society (MRASZ) is organizing the 2017 HST, which is sponsored by IARU. Hungary was the site of the first HST
    in 1995. Rules for the HST are available on the IARU Region 1 website. There are nine competition categories, based on age and sex. In general, competitors must be radio amateurs or "licensed SWLs (or SWL members of their national societies)," the rules state. Competitors will be judged on their ability to receive and transmit five-letter/figure/mixed groups for 1 minute and on their skill with RufZXP call sign recognition and Morse Runner pileup simulation software.

    The K7RA Solar Update

    Tad Cook, K7RA, Seattle, reports: All solar indicators rose over the August 17-23 reporting week, with the average daily sunspot number increasing from 15.3 to 39.9, and average daily solar flux from 72 to 84.6, compared to the previous 7 days.

    Predicted solar flux is 85 on August 24-30; 78 on August 31-September 2; 75 on September 3-7; 80 on September 8; 85 on September 9-14; 88 on September 15-16; 90 on September 17-22; 85 and 80 on September 23-24; 78 on September 25-29, and
    rising to 85 on October 6-7.

    The predicted planetary A index is 14 and 8 on August 24-25; 5 on August 26-29;
    10, 24, 18, and 14 on August 30-September 2; 5 on September 3-7; 10 and 8 on September 8-9; 5 on September 10-12; 25
    on September 13; 30 on September 14-15; 25, 8, 10, and 6 on September 16-19; 5 on September 20-25; 12, 24, 18, and 14 on September 26-29; 5 on September 30-October 4, and 10 and 8 on October 5-6.

    Did you witness the eclipse on Monday? I found a group of my neighbors gathered
    on the street corner after 1700 UTC, and they had one of those taped-together box arrangements for projecting the image. We were in Seattle, north of the band of darkness that spread over northern Oregon, south of us. Someone drove by with a box full of special eclipse-safe glasses, and they worked very well.

    Reports from friends who travelled to Madras, Oregon, reported that in the middle of the totality band, they saw the sky go totally dark, and stars illuminated the sky.

    Sunspot numbers for August 17-23 were 30, 41, 33, 44, 43, 48, and 40, with a mean of 39.9. The 10.7-centimeter flux was 76.7, 80, 86.8, 86, 87.1, 90.2, and 85.1, with a mean of 84.6. Estimated planetary A indices were 29, 21, 31, 22, 11, 23, and 25, with a mean of 23.1. Estimated mid-latitude A indices were 20, 20, 23, 21, 13, 16, and 17, with a mean of 18.6.
