via the ARRL: Nature Article Suggest a “Grand Solar Minimum” Lies Ahead

A juried research paper in Nature, “Oscillations of the baseline of solar magnetic field and solar irradiance on a millennial timescale,” suggests that a “grand solar minimum” — similar to the legendary “Maunder Minimum” — is approaching, starting as early as next year and lasting for three solar cycles. That would be bad news for HF enthusiasts, who are […]

via the ARRL: Reverse-Polarity Sunspot Group Does Not Belong to Cycle 25, Observatory Says

The Royal Observatory of Belgium’s Solar-Terrestrial Centre of Excellence (STCE) has asserted that the reverse polarity sunspot group 2720 observed in late August belongs to the current solar cycle — Cycle 24 — and does not represent the start of Cycle 25. “Because of its reversed polarity, some websites claimed sunspot group 2720 was possibly one of […]

via the ARRL: More Frequent Spotless Days Now, Can Signal Solar Activity in the Future, Top Contester Says

The sunspot numbers have not been good, and it does not seem they’ll be getting much better anytime soon. According to the April 6 “K7RA Solar Update,” only 2 days of the March 29 – April 4 reporting week saw sunspots, and that was at the bare minimum. No sunspots showed at all for the […]

via the ARRL: Higher Bands Will Pick Up this Fall, Data Suggest Smaller Solar Cycles Lie Ahead

Propagation guru Carl Luetzelschwab, K9LA, says that, while conditions on 12 and 10 meters will pick up as they always do in the fall, F2 propagation on those bands will decline thereafter, with only sporadic E during the summer months as a possible saving grace. On the other hand, the lower bands — 160, 80, […]
