- Solar activity was down over the past week, but at least the
- geomagnetic indices were lower, signalling more stable conditions.
- The A index dropped into the single digits, and there were periods
- toward the end of the week when the K index was one or zero.
-
- Unfortunately, more upsets are predicted, and the poor conditions
- could disrupt Field Day weekend. For June 25 and 26 the solar flux
- is predicted to be around 70, and the K index could go as high as
- five. Solar flux should rise again to peak near 85 around July 10.
-
- The best all around DX band should be 20 meters for the near term,
- considering the Summer season and the low solar flux.
-
- Sunspot Numbers from June 16 through 22 were 80, 53, 49, 60, 25, 38
- and 20, with a mean of 46.4. 10.7 cm flux was 87.9, 83.9, 78.4,
- 77.6, 76.4, 74.4 and 72.2, with a mean of 78.7.
-
- There is more than one path projection for this week, and they are
- domestic forecasts for Field Day weekend.
-
- >From Southern California to the New England states 80 meters looks
- good from 0200 to 1030z, peaking around 0430. 40 meters looks good
- from 0030 to 1230, peaking from 0400 to 0900. Check 20 meters from
- 0000 to 0300. 10 and 15 meters do not look promising.
-
- >From Texas to Ohio 80 meters looks best from 2330 to 1230z, peaking
- from 0230 to 0930. 40 meters just might be open around the clock,
- but will most probably be good from 1830 to 1200, with the best
- period from 0200 to 1000. 20 meters does not look good, but check
- from 2100 to 0000 and 0230 to 0500. 15 and 10 meters do not look
- good.
-
- Finally from Oregon and Washington to Florida, 80 meters looks good
- from 0230 to 1100z, peaking from 0430 to 0930. 40 meters looks good
- from 0130 to 1230, peaking from 0400 to 1000. 20 meters looks great
- from 0230 to 0430, and may open as early as 2000 and close as late as
- 1000.
