> Average daily sunspot numbers for the week were down 16 points to
> 27.4 from the previous week. Geomagnetic conditions were unsettled
> on Monday through Wednesday, January 15-17. For the near term don't
> look for any radical changes in activity, with the next period of
> moderate geomagnetic activity set for January 30. Expect geomagnetic
> conditions to become progressively quieter over the next few days.
> Geophysical Institute Prague predicts unsettled conditions for
> today, January 19, quiet to unsettled January 20 and 21, and quiet
> on January 22-25.

> Bill Van Alstyne, W5WVO of Rio Rancho, New Mexico wrote to say that
> this winter's 6-meter E-layer propagation season has been poor.
> East Coast operators have had one or two more openings than western
> states. Bill has counted three openings in New Mexico, on December
> 8-9, December 12-13, and January 8-9. "The guys I have worked in the
> northwest, north-central, south-central, and midwest states have all
> said the same thing about their Es experiences thus far this winter:
> Lousy."
> 
> Bill's 6-meter QSOs have been running close to 70 percent behind
> last year's, with only 50 so far, but 160 at this time in 2006.
> Bill notes that 6-meter operators he's talked to in the Northwest,
> North Central, Midwest and South Central states are reporting the
> same experience.

> 546 miles east-northeast of Bill in Wichita, Kansas, Jon Jones, N0JK
> is quite excited about the January 8-9 6-meter opening. He says it
> sounded like a summer opening at times, and on one occasion he had
> stations from the 2, 3, 4, 5, 7 and 8 call areas coming in at the
> same time. On January 9 on 2-meters, Kansas and Oklahoma stations
> worked North Carolina and Florida. Jon worked XE1MM and XE3ARV on
> 6-meter CW on January 9, and he noted that XE3ARV is about 2300 km
> (a little over 1400 miles) from him.

> Ray Parker, ND6S of Sutter Creek, California wrote to report the fun
> he's had at the bottom of the solar cycle working Africa on 15 and
> 20 meters this month. 100 watts worked 3DA0TM in Swaziland on
> January 4 at 2109z on 20 meters and XT2C in Burkina Faso on January
> 11 at 1824z on 15 meters with great signals. Running the average
> sunspot numbers during those times through propagation prediction
> software for the paths to Burkina Faso and Swaziland from W6 showed
> those were good times of the day for that propagation.

> Dave Mays, W8UI of Saint Marys, West Virginia mentioned a
> "Handiman's Guide to Solar Activity and HF Propagation for the
> QRPer" by Paul Harden, NA5N, that Dave read about in the ARRL
> Contest Rate Sheet. The guide is carried on the web by the GQRP Club
> at, http://www.interalia.plus.com/SOLAR_HO.pdf. The GQRP web site is
> at, http://www.interalia.plus.com. This single-sheet resource
> illustrates sunspot groups and has a guide to geomagnetic indices
