"Cycle 25 Is On the Way"

We are pleased to announce that Carl Luetzelschwab, K9LA, will be our special guest presenter at the March 4 monthly meeting.

PLEASE NOTE: We will be starting the meeting at 1900 hours with Carl's presentation, and conduct the regular club business portion following his presentation and the Q&A session.

Carl will start his presentation with a review of solar cycles and why they are important. He will follow up with a quick look back at Cycle 24, then review the predictions for Cycle 25 and what to expect now while we're still at solar minimum and what to expect in the next several years.

He will go over space weather data and list what he thinks is important as Cycle 25 rises. Carl will conclude his talk with some simple antennas for 15 meters, 12 meters, 10 meters and 6 meters so you can take advantage of the increased number of sunspots.
