Merry Christmas and Happy New year to all of you.
May next year brings to you lot of DX and many successful Ham Radio activities.
In the plot, left, black curves are solar cycles; the amplitude is the sunspot number. Red curves are geomagnetic indices, specifically the Inter-hour Variability Index or IHV. "These indices are derived from magnetometer data recorded at two points on opposite sides of Earth: one in England and another in Australia. IHV data have been taken every day since 1868," Cross correlating sunspot number vs. IHV, they found that the IHV predicts the amplitude of the solar cycle 6-plus years in advance with a 94% correlation coefficient.
According to their analysis, the next Solar Maximum should peak around 2010 with a sunspot number of 160 plus or minus 25. This would make it one of the strongest solar cycles of the past fifty years—which is to say, one of the strongest in recorded history.
A great dxpedition in Swain’s Island has been announced for March 2007. The call they will use it is N8S. Among the famous hams in the crew it will be a Greek one: Vangelis, SV2BFN. I think it is the first time that a Greek amateur participates in such a big event. We all of us wish to them great success.
I thought it was time to clean my tuner: a Palstar AT1KM. I have to admit the feeling of a robust construction that hit me at the first glimpse without the cover. I cleaned the coil carefully with isopropyl alcohol even I didn’t see any sign of dirty after a year of service. I put it up together again with that kind of satisfaction that hams experience after any successful job of repair.
