The\nlast time this gaseous stream lashed our planet's magnetic field,\nalmost a month ago, it sparked bright ribbons of purple light\n(a.k.a. 'STEVE') seen from multiple US states. Visit today's edition\nof http://www.spaceweather.com for more information.\"\n\nThe Sun remained active over the past reporting week. Average daily\nsolar flux rose from 70.1 to 74.9, and average daily sunspot number\nrose from 7.7 to 26.3. During the previous week in which the average\ndaily sunspot number was 7.7, the first four days had no sunspots.\n\nNew sunspot regions appeared on May 21, 23 and 24.\n\nPredicted solar flux is 77 on June 1-3, 76, 74 and 72 on June 4-6,\n70 on June 7-8, 71 on June 9, 72 on June 10-14, 70 on June 15-17, 72\non June 18-23, 73 on June 24, 72 on June 25-30, 70 on July 1-6, 72\non July 7-11, 70 on July 12-14 and 72 on July 15.\n\nPredicted planetary A index is 25 on June 1-2, 15, 12 and 8 on June\n3-5, 5 on June 6-12, 8 on June 13, 5 on June 14-18, 8 on June 19, 5\non June 20-23, 8 on June 24-25, 5 on June 26-27, then 15, 28, 15,\n12, 10 and 8 on June 28 through July 3, then 5 on July 4-9, 8 on\nJuly 10, and 5 on July 11-15.\n\n2018 ARRL Field Day is June 23-24. Assuming the predicted numbers\nabove, conditions should be good for Field Day. We want to see low\ngeomagnetic activity, and planetary A index at 5 and 8 on Saturday\nand Sunday are good indicators. During this period of low solar\nactivity solar flux at 72 and 73 is also good.\n\nTed Leaf, K6HI of Kona, Hawaii reports that he is still in operation\nthrough the local volcanic activity, and asks, \"Are there beacons\nfor the lower frequencies, especially now with the lower solar\nflux?\"\n\nI found this Wikipedia resource for HF beacons:\n\nhttps://en.wikipedia.org/wiki/Amateur_radio_propagation_beacon\n\nOf course, there are lower frequency HF resources on\nhttp://www.wsprnet.org, but this is a bit different than showing\nwhat you can tune in and hear without using a special weak signal\nmode.\n\nAny readers have suggestions for lower frequency HF beacons?\n\nNote that Ted has a comment on page 56 of the June 2018 QST\nregarding preamps and attenuator effects on receiver noise.\n\n>From last week: https://bit.ly/2LG8MAp\n\nF.K. Janda, OK1HH brings us this geomagnetic activity forecast for\nthe period June 1-26, 2018.\n\n\"Geomagnetic field will be:\nQuiet on June 11-12, 16-17, 20-23\nQuiet to unsettled on June 10, 18, 24-25\nQuiet to active on June 8-9\nUnsettled to active on June 3-4, 7, 13-15, 19\nActive to disturbed on June 1-2, (5-7, 26)\n\n\"Solar wind will intensify on June 1-3, (4-8, 13-15), 16-17, (18-19,\n22-24)\n\n\"Remark:\n- Parenthesis means lower probability of activity enhancement.\n- Forecasts remain less reliable.\"\n\n>From Dr. Tamitha Skov, the Space Weather Woman:\n\n\"What's Old is New Again\n\n\"Dear Tad,\n\n\"I am still smiling at the huge response I got to a post I put up on\nTwitter this week. A newbie to our Space Weather community dared to\ntalk about amateur radio as if it were an outdated hobby-- whoops,\nbad idea. I gently educated him. In doing so, I roused many radio\namateurs and emergency communicators, who added their own comments\nand talked about their own personal experiences in the field. It was\nvery gratifying. What I hadn't expected, however, was the strong\ninterest in the concept that amateur radio will be critical to\nestablishing over-the-horizon radio communications on planets like\nMars in the near future.\n\n\"This idea brings me back to how we managed to communicate over long\ndistances many decades before we had satellites, internet or\ncellular networks. In terms of wireless communications on Earth, we\nwere very much in the same place back in the early 1900s that we\nfind ourselves in now when we think about colonizing Mars. Yet few\npeople realize that despite all our advanced technology, we can't\nbring a cell phone to Mars. We will need to fall back on our 'old\nways' of doing things when it comes to communicating on other\nplanets. Isn't it funny how 'old' things become 'new' again?\n\n\"Speaking of, this week brings us a new chance for a decent solar\nstorm. Strangely though, the source of this storm is an old coronal\nhole that gave us a moderate level solar storm about a month ago.\nThis old hole has survived its backside passage on the Sun and has\nnow returned, with the new promise of bringing aurora views down to\nmid-latitudes again. Isn't it funny, what was old has become new\nagain, in more ways than one!\n\n\"Cheers, Tamitha\"\n\nDr. Skov's latest video report:\n\nhttps://www.youtube.com/watch?v=QwvKyY26lB0\n\nIf you would like to make a comment or have a tip for our readers,\nemail the author at, [email protected] .\n\nFor more information concerning radio propagation, see the ARRL\nTechnical Information Service web page at,\nhttp://arrl.org/propagation-of-rf-signals.

A SSTV\nCamera Transmitter (400 - 500 mW) will take a photo and transmit it\nevery 5 minutes. The call sign is ZR6MUG and will transmit on 144.500\nFM, Martin 1 Mode and you will need MMSSTV to decode. A Telemetry\nTransmitter (400 - 500 mW) will transmit telemetry data every 30\nseconds under the call sign ZR6TG on 144.600 FM and you can use\nFLdigi to decode. And an APRS Transmitter (300 mW) will transmit\nposition and altitude every minute on 144.800 MHz under the call\nZR6TG-11. We will also have a Go-pro camera and a Science Lab\n(Raspberry pi based with lots of sensors) in the payload. The payload\nis estimated to be around 900 g and we are using a 1 000 g white\nballoon.\n\nThere are several prizes and awards available. The first person to\nrecover the payload will get a prize and footage of the payload\ncoming down will receive a prize.
