The average daily sunspot numbers this week were about the same as last week, while the average daily solar flux declined a little more than eight points to 128.9. Geomagnetic indicators were quiet. The average daily sunspot numbers of 95.3 for the week is considerably below the average for the previous 90 days, which was 120.8. Sunspot numbers for December 15-21 were 44, 60, 95, 103, 133, 139 and 93, with a mean of 95.3. The 10.7 cm flux was 124.2, 121, 119.6, 127.4, 128.2, 137.4 and 144.5, with a mean of 128.9. The estimated planetary A indices were 0, 0, 0, 1, 4, 3 and 3, with a mean of 1.6. The estimated mid-latitude A indices were 2, 2, 2, 3, 6, 5 and 5, with a mean of 3.6.
The solar flux has been climbing over the past week, after a low of 119.6 on December 17. The predicted flux values for the near term are 145 on December 23, 140 on December 24-27, 145 on December 28-30, then dropping suddenly to 120 on December 31-January 2, 125 on January 3-4, 128 on January 5-8, and then peaking at 130 on January 9-17. The predicted planetary A index is 5 on December 23 through January 4, 8 on January 5-6, and 5 on January 7-21. This is from NOAA and the U.S. Air Force Space Weather Operations. There is another opinion, of course: Geophysical Institute Prague predicts quiet conditions December 23, quiet to unsettled December 24, active conditions December 25, unsettled to active December 26, quiet to unsettled December 27 and quiet again on December 28-29.
Active conditions are quite different from an A index of 5, although the NOAA/USAF outlook is at least eight hours newer than the Prague prediction. But looking back 24 hours earlier to the December 21 prediction, USAF/NOAA has nothing different on December 25, although they do show an A index of 8 on December 29.

Yaesu’s Amateur Radio Division Breaks with Motorola, Changes Name to Yaesu Musen
Loyd C. Headrick Published Date Hits: 63
After four years under the Motorola umbrella, Yaesu has split from that company. According to Vertex Standard President and Chief Executive Officer Jun Hasegawa, effective January1, 2012, Motorola will keep the Vertex Standard Land-Mobile Division, while the amateur, marine and air-band will be under the Yaesu Musen banner. The new company will be known as Yaesu USA here in the US.
“This reorganization will allow us to concentrate in amateur, marine and air-band business, which will better leverage and align the strengths of our entire business operation,” Hasegawa said in a press release dated December 27. “We believe that there is an exciting opportunity to evolve our organization to meet the needs of the Amateur Radio, Marine equipment and air band telecommunication industries by continuing to provide specialized services and the highest quality products.”
Hasegawa explained that the new company’s name will be Yaesu Musen, “a name our business partners have been familiar with for over 50 years. We are delighted to bring you the legacy of trust, quality and solid customer service that has always been associated with the Yaesu Musen company name.”
While Yaesu Musen will have a new Japanese address, the address and phone numbers -- as well as the US operations and sales organization -- for Yaesu USA will not change. Dennis Motschenbacher, K7BV, will remain in charge of Yaesu USA’s sales division.
