> Sunspot counts were lower this week, but it is surprising what has
> happened on the ham bands. Operators are still having fun, and still
> working long distances, even on VHF, during this low part of the
> sunspot cycle. Most of this is due to seasonal sporadic-E
> propagation.
> 
> Average sunspot numbers dropped 35 points to 19.3 between the last
> week in May and the first week of June. Geomagnetic indexes were a
> little higher.
> 
> In 6-meter news, Scott Avery, WA6LIE in Salinas, California (CM96)
> says that on June 1 he worked four stations in Florida from
> 0000-0100z.
> 
> Jim Henderson, KF7E near Phoenix, Arizona said on June 2 that
> 6-meter conditions on the previous weekend were exceptional, with
> propagation to the Carolinas on May 27 and New England on May 28.
> May 29 saw openings to Vermont, Connecticut, Maine and New York, and
> then "a huge opening to the Pacific Northwest."
> 
> Jim also sent along an interesting link to a map of electron
> densities, along with plots of reported 6-meter propagation. You can
> see it at,
> http://69.15.204.66/ionosphere/DesktopDefault.aspx?tabindex=3&tabid=34.
> 
> Shelby Ennis, W8WN of Elizabethtown, Kentucky sent a link to,
> http://www.vhfdx.net/spots/map.php, that shows real-time maps of VHF
> propagation. You can select maps for different bands and various
> regions.
> 
> There were also reports of great HF conditions during the CQ WPX
> contest over the Memorial Day weekend. Sig, N3RS of Glenmoore,
> Pennsylvania said he could work Europe until the wee hours on 20
> meters, and he had 15 and 20-meter propagation to Japan as well.
> 
> Gordon Fogg, N5AU of Rockwall, Texas said that on Sunday night and
> Monday, June 4-5, he experienced an amazing 6-meter opening to
> Japan. He worked 17 JA stations on CW, and heard many other stations
> working them also.
> 
> Jon Jones, N0JK of Wichita, Kansas characterized the 6-meter opening
> to Japan on Sunday night, June 4 as "massive sporadic-E." Jon said
> the Sunday Japan opening favored Texas, Oklahoma, Kansas and
> Colorado. On Monday stations as far east as Florida, Ohio and
> Alabama worked Japan on 6-meters. On Sunday evening, Jon used 100
> watts and a 2 element Yagi atop the parking garage at the hospital
> where he works and he contacted JA7QVI around 2345z on 50.101 MHz.
> 
> Chip Margelli, K7JA of Garden Grove, California wrote to urge
> contact with WQ5W, who worked "at least 34 JAs" on 6-meters on
> Sunday. Chip worked JH0RNN and JA7QVI on CW.
> 
> Alan Benoit, WQ5W wrote, "Yes, we had an amazing opening into JA on
> Sunday evening from here in EM12 (near Fort Worth). I worked NL7Z at
> 2218z on SSB and then noticed in the 6M chat room that JH2COZ was
> going to call CQ on 50.096 MHz CW. Not expecting anything, I
> listened for his CQ and to my amazement, I heard him 559. He came
> back immediately to my call and I worked my first JA ever on 6M!"
> 
> Alan continues, "I then proceeded to call CQ on CW further up the
> band and had many JAs call me! Between 2227z and 0151z I made 42
> QSOs into JA along with 2 KL7s and a few VE7s (all on CW). It was
> the most amazing thing I've ever experienced on 6M. I believe all of
> this was via Es which makes it even more amazing."
> 
> This weekend is the ARRL June VHF QSO Party, a nice excuse for
> searching for more 6-meter excitement.
