The K7RA Solar Update

Fri, 06/09/2017 - 09:55

The big event this week was multiple sporadic-E linkups on 6 meters yesterday (June 8).

The average daily sunspot number rose this week from 15.6 to 19.3. This was largely due to the fact that there was one zero-sunspot day last week, and no days with zero sunspots this week.

The average daily A index, planetary and mid-latitude were both 5.6 this week. Last week they were 13.3 and 10.6.

Centenarian ARRL Member Claiming Oldest Active Radio Amateur Crown

Wed, 06/07/2017 - 14:21

A 105-year-old ARRL member, Cliff Kayhart, W4KKP, of White Rock, South Carolina, is claiming the title of “World’s Oldest Operating Ham.” No official record of such milestones exists, but ARRL is not aware of any radio amateurs senior to Kayhart, and he is now quite likely the oldest active ham at least in the US. Early this year, Charlie Hellman, W2RP, died at 106; he also may have been the lo...

Our Sun’s 11-Year Magnetic Cycle Destined to Disappear

Thu, 06/01/2017 - 14:19

The Sun’s 11-year magnetic cycle appears to be ending, but that won’t happen anytime soon. In a paper submitted on May 26 to the journal Solar Physics, two solar scientists are reinterpreting earlier evidence to hypothesize that the Sun’s rotation rate and magnetic field are in a transitional phase that could lead to lengthening solar cycles, with the cycle ultimately disappearing altogether be...
