The K7RA Solar Update

04/28/2017

Each of the average solar and geomagnetic indices rose last week (April 20-26) over the previous seven days.

Average daily sunspot number rose from 8.6 to 35.7, and solar flux rose from 76.5 to 81.4.

Average daily planetary A index went from 8 to 26.4, and average daily mid-latitude A index from 6.3 to 18.4.

The day with the most geomagnetic activity was April 22 when the planetary A index was 54. One the same date, Alaska’s College A index (near Fairbanks) was 86.

Predicted planetary A index is 8, 5 and 5 on April 28-30, then 14, 10, 8 and 10 on May 1-4, 15 on May 5-6, 8 on May 7-8, 5 on May 9-14, 8 and 15 on May 15-16, and then into a more active period at 30, 25, 45, 50 and 30 on May 17-21.

Announcing the BS7B DXpedition to Scarborough Reef !

FOR IMMEDIATE RELEASE

After a lot of negotiation, we are pleased to announce a team of twelve has been granted permission to activate Scarborough Reef from 28 March 2018 to 8 April 2018.

Territorial disputes are so last century so we have gained permission to operate from the organisations that really matter, Google, Amazon, Twitter, Apple, Facebook, Snapchat, Airbnb, Uber, Spotify and Tesla, (Tesla doesn’t actually have anything to do with the South China Sea but we just wanted to talk to them as they are really cool).

Interestingly none of them could figure out in this day and age why we need radios or would even want to go to Scarborough Reef. But we are excited to announce they are supporting us in setting up the world’s first fully remote DXpedition. We are setting up five remote stations on the rocks and then operating from the comfort of a five star hotel in Japan (with regular room service). In case you guys haven’t realised, the internet is where it is at. Accordingly there will be none of this risking life and limb on a bunch of rocks which may disappear during the operation because of climate change or a storm, going somewhere that doesn’t have a decent Chinese takeaway, or risk being shot at because people from a number of countries didn’t get the memo that tech companies rule the world.

Quiet to unsettled April 19, 29, May 1, 2, 7, 8
Quiet to active on April 23, 25-28
Active to disturbed on April 17-18, 24

"Amplifications of the solar wind from coronal holes are expected on April (15,) 16-19, 24-27

"Remark: - Parenthesis means lower probability of activity enhancement and/or lower reliability of prediction."

Bil Paul (I think he must be KD6GUI) wrote on April 7:

"The high solar flux number for Wednesday, April 5 (around 95) didn't seem to translate into good propagation. I was out in my kayak trying to qualify an island in Northern California for U.S. Islands on the Air, running my usual 10w into an end-fed half-wave wire vertical (won't even get into how I can set that up while operating from kayak!).

"As usual, started operating on 17m SSB. One contact told me I was the only signal he was hearing on the entire band. Only obtained 3 contacts on 17 (SSB/CW), then went down and tried 20m. I could hear Europe and South America coming in on SSB, but from my little pistol setup, I only found 3 more contacts before I rolled up the rug and went QRT.

"But it's encouraging that the SF is often predicted to be running considerably higher for the next 30 days or so.

"I don't know if you read CQ magazine, but I have an article in the April issue about a 91-year old ham/navy vet in PA who intercepted Japanese code transmissions in Alaska during WWII."

Sunspot numbers for April 6 through 12, 2017 were 38, 27, 0, 13, 13, 12, and 13, with a mean of 16.6. 10.7 cm flux was 75.7, 73.9, 73.1, 74.4, 73.6, 74.6, and 71.4, with a mean of 73.8. Estimated planetary A indices were 7, 10, 16, 18, 5, 12, and 6, with a mean of 10.6. Estimated mid-latitude A indices were 5, 9, 14, 16, 5, 10, and 6, with a mean of 9.3.
