- Solar activity rose again last week, with flux an average 17 points
- higher than the week previous. New Years Day was the biggest treat,
- with the flux at 148.3, higher than on any day since March 12, 1993.
- Coronal hole activity produced some geomagnetic disturbances, but
- nothing really major.
-
- Solar flux should fall this week, dropping to 100 around January 12,
- and then rise again toward a peak around January 26 of 140. There
- is a chance of some moderately disturbed conditions around January
- 12 or 13, and again, but possibly more severe, around January 28.
-
- Sunspot Numbers from December 30 through January 5 were 110, 134,
- 130, 94, 134, 131 and 154, with a mean of 126.7. 10.7 cm flux was
- 142.8, 140.8, 148.3, 146, 133.1, 128.8 and 136.9, with a mean of
- 139.5
-
- The path projection for this week is from Garland, Texas to Brazil.
- It is based on a flux of 115 for Saturday, January 8.
-
- 80 meters should be good from 2330z to 0930z, with the best time
- from 0130z to 0830z. 40 meters looks good from 2300z to 1000z, with
- the best conditions from 0030z to 0900z. 30 meters should be open
- from 2230z to 0800z or 0900z, with the best bet for propagation from
- 0000z to 0200z, and from 0630z to 0800z. 20 meters should be good
- from 1900z to 0030z, although on some days it may be open as early
- as 1300z and as late as 0600z. 17 meters looks good from 1400z to
- 2230z, and 15 meters from 1500z to 2130z. 12 meters should be open
- from 1600z to 1900z, and on some days as early as 1500z and as late
- as 2200z. 10 meters looks marginal over this path, but on many days
- it could be open from 1600z to 2100z.
