qst de ad7i hr propagation forecast bulletin nr 47 from arrl headquarters newington ct november 21, 1983 to all radio amateurs bt the solar flux curve continued downward, from 111 on november 9 to 82 on the 20th. the most recent 82 was recorded september 1, 1577, only 14 months into the present solar cycle. this does not indicate that we are 14 months from the end of cycle 21. solar activity rises rapidly in the early years of the cycle, but the decline afternthe peak is much more gradual. loss of dx on 28 mhz this fall has resulted from high geomagnetic activity rather than from the considerably lower solar flux values in recent weeks. propagation was no better than fair from november 8 through 20. things shokld improve early in the forecast week, holding up from at least the 24th. the solar flux will be rising again by then, but geomagnetic activity will be high intermittently from the 26th to the rest of the month. the next really good conditions after this thursday should begin about december 2. american sunspot numbers for november 10 through 16 were between 25 and 62 with a mean of 39 ar
