The K7RA Solar Update

The sun is blank–no sunspots. Credit: SDO/HMI

According to Spaceweather.com, as of June 5 there have been no sunspots for 17 days in a row. Average daily solar flux went to 69.5 this reporting week (May 30 through June 5) from 67.4 in the previous seven days. Average daily planetary A index declined from 7.3 to 5.6, while mid-latitude A index went from 8.1 to 5.

Last week I mentioned that sunspots should return soon, based on the predicted solar flux, but those projections have softened. On June 6 the 45-day predicted solar flux was 70 on June 7-14, 72, 72 and 71 on June 15-17, 70 on June 18-29, 71 on June 30, 72 on July 1-13, 71 on July 14, and 70 on July 15-21.

Predicted planetary A index is 8, 10 and 8 on June 7-9, 5 on June 10-22, then 8, 10, 12 and 8 on June 23-26, 5 on June 27-29, 8 on June 30 through July 2, 5 on July 3-4, 8 on July 5-6, 5 on July 7-19, then 8 and 10 on July 20-21.

Spaceweather.com sent this alert on June 5: “A DAYTIME METEOR SHOWER IS UNDERWAY: Radars in the northern hemisphere are pinging with activity as one of the strongest meteor showers of the year takes place in broad daylight. The source of the shower is sun-grazing Comet 96P/Machholz.”

Dick Bingham, W7WKR, alerted us to this, and wrote: “What a fine six-meter opening this afternoon! I copied many of you on FT8 working across the country. The one I really would have enjoyed capturing was NW1P in FN67 – probably the only person in the USA there. Listening to all the meteor-echoes was impressive. Seemed like up to 10 per minute for a while.”

Jon Jones, N0JK, wrote: “I enjoyed reading N8II’s detailed report of his activity in the WPX CW this year. I noted his rare Hawaiian contact on 10-meters described in the W1AW bulletin at http://www.arrl.org/w1aw-bulletins-archive/ARLP022/2019.

“Six meters was also open from Hawaii to the mainland USA on May 25. At almost the exact same time Jeff worked WH7V on 10 meters, VE2XK worked NH6Y on 6 meters:

NH6Y  19/05/25 1859Z  50313.0 FN07 ES BL10 TU FT8 qso & grid  VE2XK NH6Y  19/05/25 1857Z  50313.0 DN70MQ ES BL10TS                K0GU

“No Hawaii contacts from here in Kansas, but I logged KP4EIT and KP4AJ on 6-meter FT8 at about 2000 UTC on May 25.”

Geomagnetic activity forecast for the period June 7 to July 3, 2019 from F.K. Janda, OK1HH.

Geomagnetic field will be: Quiet on June 13, 16-18, 28, 30, July 1, 3 Quiet to unsettled on 8, 10-11, 14, 19-22, 27, 29 Quiet to active on June (12, 15,) 26, July 2 Unsettled to active on June (7, 9,) 23-25 No active to disturbed days expected.

Solar wind will intensify on June 10-14, 24-27

Parenthesis means lower probability of activity enhancement.

Monster Region Returns & Alien Aurora 04.10.2019

“This week old region region 2736 (renumbered 2738) returns to Earth view, giving the solar flux a much needed boost. This means radio propagation returns to the high side of marginal for amateur, shortwave radio & emergency operators on Earth’s dayside. Luckily, this monster region is not a threat for big flares or radio blackouts so GPS users should continue to enjoy decent reception, especially on Earth’s dayside.

Aurora photographers at high latitudes also get another brief chance for aurora views this week due to another small pocket of fast solar wind expected around April 12-13. On top of that, we have had some very strange lights in the sky recently due to a NASA rocket mission to study aurora (called AZURE). Learn the details of these stories, what conditions to expect and what else our Sun has in store this week.”
