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.

On Tuesday, October 6, Senator Joe Lieberman (ID-CT), along with Senator Susan Collins (R-ME), introduced Senate Bill 1755, The Amateur Radio Emergency Communications Enhancement Act of 2009. Similar to HR 2160 -- also called The Amateur Radio Emergency Communications Enhancement Act of 2009 -- that was introduced this past April by Representative Sheila Jackson-Lee (D-TX-18), the bill, if passed, would direct the Department of Homeland Security (DHS) to undertake a study on emergency communications. S 1755 points out that "There is a strong Federal interest in the effective performance of Amateur Radio Service stations, and that performance must be given -- (A) support at all levels of government; and (B) protection against unreasonable regulation and impediments to the provision of the valuable communications provided by such stations.""We are delighted to have the sponsorship of both the Chairman and the Ranking Member of the Homeland Security and Governmental Affairs Committee, and especially to have the support of Senator Lieberman from the ARRL's home state," said ARRL Chief Executive Officer David Sumner, K1ZZ. "The bill could not have a better pedigree. Click here for more information on S 1755."
