The average for the week, 117.5, was transposed into the solar flux number for the last day of the reporting period. The Winter Solstice was on the date of the last Propagation Forecast Bulletin, ARLP051, on Friday December 21, at 1112z. Average daily solar flux was down this week about four points to 113.4, which coincidentally was the solar flux number for the last reporting day of the previous week. Average daily sunspot numbers were down 6.7 points to 65.4. Geomagnetic indices were very low and stable, which should please 160 meter operators, who are also enjoying the long periods of darkness in the Northern Hemisphere. For more information concerning radio propagation, see the ARRL Technical Information Service web page. A detailed explanation of the numbers used in this bulletin is also available on this site. An archive of past propagation bulletins is also available. Sunspot numbers were 53, 55, 67, 90, 53, 58, and 82, with a mean of 65.4. 10.7 cm flux was 114.1, 114.6, 115.3, 114.2, 113.1, 113, and 109.8, with a mean of 113.4.
