PLEASE NOTE: 25 December 2021 - WR-3 Receiver construction is ongoing and I continue to list in batches of 3 to 4 WR-3 Receivers on eBay (vlfradio) monthly or so. They do sell out quickly. Perform an eBay search for "WR-3 ELF-VLF Receiver" and the listing should appear first. Please write me to receive notice of new units ready to be sold & shipped. Thanks everyone, everywhere, for your fascination with Earth's lovely Natural-Radio signals! Please READ the WR_3 Listening Guide FULLY before eBay-ordering, please!

Manitoba Aurora - Aug. 1996 photo

A Summer 1996 photo of gorgeous aurora over northern Manitoba, Canada, taken during my Manitoba Solar-Minimum VLF Expedition way back on 22 August 1996. Central/Northern Manitoba, Canada is an excellent region in North America (in late-Summer when it is still mild weather) to see gorgeous Aurora Borealis. If you wish to witness this incredible spectacle for yourself, you don't have to wait until the cold/dark of winter to go northward to see gorgeous Aurora if you head for central/northern Manitoba or Saskatchewan, Canada in late August or early September. I love the vast Canadian Boreal Forest region for its feeling of deep-wilderness! - "The True North Strong and Free."

Furthermore, I cannot recommend highly enough to anyone whom wishes to see the aurora for yourself--from experience I can highly suggest that the finest period is the four weeks surrounding 01 September. Presently, auroral displays and also natural-radio phenomena are at a minimum due to overall minimal solar-activity as we finally-depart a deep Solar-Minimum (late 2020). The Solar-Flux (2800 MHz_ reached 101 on 08 September 2021 and large sunspot groups are appearing at high solar latitudes, thus exhibiting good signs of the coming Cycle 25 rising-up along with a ramping-up of good outbtreaks of fine natural radio listening and phenomena. Aurora appears most frequently and brightly during the equinoctal periods around late-September and early-April (due to the alignment of Earth's magnetic-field and the IPF). Periods of fast solar-wind streams (>500 to 600 km/sec speeds) will often produce nice aurora and potentially a magnetic storm, too -- conditions ripe for whistlers.

Thus, late August through mid-September will definitely present the mildest/warmest weather for viewing (short sleeves/pants weather) Summer Prairie-Beauty Canadian weather! Do head for Canada's High Plains/Boreal Forest region in late Summer. To be deep into the optimal locations under the auroral-oval for the most superb Aurora enjoyment, journey up toward Thompson, Manitoba; The Peace Country of Alberta; or Hay River, NWT (as I did in June 1996). Find an electrically-quiet camping location and enjoy the ELF-VLF show, too! (We are coming out of a very low Solar-Minimum presently and so the signals are considerably more rare and challenging to capture compared to my previous recording-expeditions presented herein.

This is my website presenting the span of the time-period between June 1989 to the present in 2021 that I have been researching and field-recording natural ELF-VLF radio phenomena (primarily) via the Magnetosphere, and other forms of radio "DXing" also.
