- Conditions were fairly good until May 1, when the previously
- predicted cycle of disturbances from a coronal hole began again.
- Solar flux was down a bit relative to the previous week.
-
- Poor conditions should continue until the middle of May, when
- geomagnetic activity should finally quiet down again. Solar flux
- will be rising until a peak around May 19 near 100. Flux should
- decrease again, with disturbances returning by the end of the month
- for another cycle of high K indices.
-
- Sunspot Numbers from April 28 through May 4 were 35, 16, 38, 80, 75,
- 52 and 38, with a mean of 47.7. 10.7 cm flux was 77.3, 77.8, 74.9,
- 75.2, 75.9, 74.4 and 73.1, with a mean of 75.5.
-
- The projection for this week is from Larsen Bay, Alaska, on Kodiak
- Island, to New Zealand.
-
- 80 meters should be open from 0000 to 1500z, and 40 meters from
- 0630 to 1530. Check 30 meters from 0530 to 1600, and 20 meters
- from 0430 to 0700. 17 meters should be open from 0300 to 0430,
- and on same days as late as 0600. 10, 12 and 15 meters do not look
- good at this time. All of this assumes that geomagnetic conditions
- are not terribly stormy, which tends to create problems for
- propagation in the higher latitudes.
