The
long string of days with no sunspots continues, with spots last observed nearly
a month ago, on May 18. According to spaceweather.com
Predicted solar flux for
the next 45 days is 68 on June 14 through July 28. That’s right, the prediction
updated on June 13 is nothing but 68 on every day for the near
future.
Predicted
planetary A index is 8 on June 14, 10 on June 15-18, 8 on June 19, 5 on June
20-23, then 8, 12 and 8 on June 24-26, 5 on June 27 through July 5, then 10, 8,
10 and 8 on July 6-9, then 5 on July 10-20, then 8, 10 and 8 on July 21-23, and

The ARRL June VHF Contest was last weekend, and Scott Avery, WA6LIE, reports, “This last VHF contest was definitely unique. During the day expecting sporadic E, we were influenced by a lot of meteor scatter caused by the Beta Taurids, a daytime event that is not advertised as it is not seen and only radio astronomers and hams would be interested. I spent a lot of time on 6 meters FT8 mode as there was little SSB/CW activity. Two meters was the same.
“I
was bombarded with pings CQ TEST, but then the signal would vanish. This
happened for most of the daylight hours with few exchanges. MSK144, which is a
true meteor-scatter mode, worked great, but everyone was on FT8, so few contacts
were made.
"At
about 0300z we had an opening to Japan that lasted for about 3 hours, so I
snagged a few contacts. That opening from Japan to the central coast of
California was about 1 hour long.
“The
Midwest enjoyed an opening to Japan on Sunday at around 2100z for about an
hour.
"Finally,
at 2200z on Sunday, we got some multi-hop Es to the east coast. It was a bit
late for the contest, but welcome.”
Jon Jones, N0JK, also sent a report on the VHF contest: "Conditions on 6 meters were uneven, but on Sunday even we had a great opening to Japan from here in the Midwest.
“Operators
in Kansas including N0LL, WQ0P, and KF0M worked Japan from 2330 to 0030z. I
de-coded JG1TSG at about 0020z with just a 1/4 wavelength vertical whip antenna
on my car.
“I
should note that W7D/R put rare grid DN10 in many logs."
Steve Sacco, NN4X, reported, “Finally, some decent E-skip on 12 meters! I was able to work S9A and some others for new DXCC entities on the band today (Sunday 6/9/2019, 1537Z on FT8).”
