ARLP023 Propagation de KT7H

There is very little solar activity to report. There was an 8 day run of no visible sunspots at the end of May, but activity has picked up slightly since then. Average solar flux is up about two points from last week's bulletin.

Solar flux should peak in the short term around 72 on June 9 and 10, and then drop down below 70 after June 14. It isn't expected to rise above 70 until after the first of next month. Geomagnetic conditions are quiet, but some moderate unsettled conditions are forecast for June 9 thru 13 and 16 and 17.

Propagation on the upper bands remains depressed. As we move toward Summer 160 and 80 meters are getting noisier. Check 30 and 40 meters during the night for worldwide propagation and 20 meters during the day.

Sunspot Numbers for May 30 through June 5 were 0, 0, 11, 11, 13, 23 and 28, with a mean of 12.3. 10.7 cm flux was 66.5, 68, 68.5, 68.2, 69.1, 69.2, and 70.7, with a mean of 68.6.
