From: skywave...@yahoogroups.co.uk [mailto:skywave...@yahoogroups.co.uk] On Behalf Of Chris Trask Sent: 24. tammikuuta 2013 15:12 To: skywave...@yahoogroups.co.uk; skywave...@yahoogroups.co.uk; vhfs...@yahoogroups.com; m...@yahoogroups.com Subject: Re: [SkywavesDX] Solar Eruptions Three years ago I spent about four months with a spreadsheet, using a formula devised by a NASA contractor that showed how the magnetic fields of the planets affect the solar flux and sunspot cycles. I elaborated on what he had published and came up with a chart that reasonably reconstructed the measured sunspot activity back to the 17th century, and which showed that this cycle and the next three are going to be very low: http://www.home.earthlink.net/~christrask/Solar%20Activity%201600-2100.pdf Unlike other predictions from NASA, ARRL, and others, I have not modified this prediction since I completed the spreadsheet some three years ago. I do update the chart by adding measured monthly average sun spots counts as they become available at the beginning of each month from the Royal Observatory of Belgium (http://sidc.oma.be/) Chris Trask N7ZWY / WDX3HLB Senior Member IEEE http://www.home.earthlink.net/~christrask/ __._,_.___ Reply to sender<mailto:christr...@earthlink.net?subject=Re%3A%20%5BSkywavesDX%5D%20Solar%20Eruptions> | Reply to group<mailto:skywave...@yahoogroups.co.uk?subject=Re%3A%20%5BSkywavesDX%5D%20Solar%20Eruptions> | Reply via web post<http://uk.groups.yahoo.com/group/SkywavesDX/post;_ylc=X3oDMTJyamZwM2pvBF9TAzk3NDkwNTA1BGdycElkAzI5MTkyNTU0BGdycHNwSWQDMTY5MDA2MzEwOARtc2dJZAMyNDE4MgRzZWMDZnRyBHNsawNycGx5BHN0aW1lAzEzNTkwMzMxMDI-?act=reply&messageNum=24182> | Start a new topic<http://uk.groups.yahoo.com/group/SkywavesDX/post;_ylc=X3oDMTJmZXRvNWdkBF9TAzk3NDkwNTA1BGdycElkAzI5MTkyNTU0BGdycHNwSWQDMTY5MDA2MzEwOARzZWMDZnRyBHNsawNudHBjBHN0aW1lAzEzNTkwMzMxMDI-> Messages in this topic<http://uk.groups.yahoo.com/group/SkywavesDX/message/24177;_ylc=X3oDMTM3YnY5bXB2BF9TAzk3NDkwNTA1BGdycElkAzI5MTkyNTU0BGdycHNwSWQDMTY5MDA2MzEwOARtc2dJZAMyNDE4MgRzZWMDZnRyBHNsawN2dHBjBHN0aW1lAzEzNTkwMzMxMDIEdHBjSWQDMjQxNzc-> (5) Recent Activity: · New Photos<http://uk.groups.yahoo.com/group/SkywavesDX/spnew;_ylc=X3oDMTJnbTRmN2xjBF9TAzk3NDkwNTA1BGdycElkAzI5MTkyNTU0BGdycHNwSWQDMTY5MDA2MzEwOARzZWMDdnRsBHNsawN2cGhvdARzdGltZQMxMzU5MDMzMTAy> 4 Visit Your Group<http://uk.groups.yahoo.com/group/SkywavesDX;_ylc=X3oDMTJmNTE2YTdvBF9TAzk3NDkwNTA1BGdycElkAzI5MTkyNTU0BGdycHNwSWQDMTY5MDA2MzEwOARzZWMDdnRsBHNsawN2Z2hwBHN0aW1lAzEzNTkwMzMxMDI-> [http://l.yimg.com/a/i/us/yg/logo/uk-ie.gif]<http://uk.groups.yahoo.com/;_ylc=X3oDMTJlYWg4ZzhrBF9TAzk3NDkwNTA1BGdycElkAzI5MTkyNTU0BGdycHNwSWQDMTY5MDA2MzEwOARzZWMDZnRyBHNsawNnZnAEc3RpbWUDMTM1OTAzMzEwMg--> Switch to: Text-Only<mailto:skywavesdx-traditio...@yahoogroups.co.uk?subject=Change%20Delivery%20Format:%20Traditional>, Daily Digest<mailto:skywavesdx-dig...@yahoogroups.co.uk?subject=Email%20Delivery:%20Digest> • Unsubscribe<mailto:skywavesdx-unsubscr...@yahoogroups.co.uk?subject=Unsubscribe> • Terms of Use<http://uk.docs.yahoo.com/info/terms.html> . __,_._,___
