<div dir="ltr"><h1>Extended solar ebb may lie ahead</h1><p> The <em>ARRL</em> report that Amateur Radio propagation guru <strong>Carl Luetzelschwab K9LA</strong> says we may be seeing an extended solar ebb <br>
<br> Amateur Radio propagation and solar phenomena authority Carl Luetzelschwab, K9LA, said in an April 27 webinar, “Are We Headed into Another Maunder Minimum? What Does That Mean for Propagation?” that most solar scientists believe several low solar cycles lie ahead, ushering in periods of diminished HF propagation, especially on the higher bands. <br>
<br> Luetzelschwab, who maintains K9LA’s Amateur Radio Propagation Web Site and pens a regular “Propagation” column for NCJ, stopped short of concluding that we’ll experience a Maunder minimum — an extended period of very few or no sunspots. As the Marshall Space Flight Center’s “Solar Physics” web page explains, early sunspot records indicate that the Sun went through an inactive period from about 1645 to 1715 — called the Maunder minimum after the scientist who discovered it — when very few sunspots were observed.<br>
<br>“Right now there’s nothing bulletproof to say we’re heading into a Maunder minimum, so we’re just going to have to wait and see,” Luetzelschwab told the webinar, sponsored by the World Wide Radio Operators Foundation (WWROF). “It sure looks like something inside the sun changed around the peak of Cycle 23. There’s lots of evidence that we’re entering a grand solar minimum. But I don’t think any of the solar scientists are 100 percent sure that we’re going to see a Maunder-type minimum.”<br>
