Title: NEW SUNSPOT! Post by: Ed-VA3ES on September 23, 2008, 11:43:54 AM A NEW SUNSPOT:
A new sunspot http://www.spaceweather.com/images2008/22sep08/midi_lab.jpg?PHPSESSID=fqqehum5f8h7dku1k760ll8c53&PHPSESSID=bohimeorlhkn8r56s3ufcqe317 is emerging in the sun's northern hemisphere. After several months of almost-relentlessly blank suns, "this is like a breath of fresh plasma," says photographer Pete Lawrence who sends this picture: http://spaceweather.com/submissions/large_image_popup.php?image_name=Pete-Lawrence-2008-09-22_10-24-21_SF100ss_1222082083.jpg from Selsey, UK. The magnetic polarity of the emerging spot identifies it as a member of new Sunspot Cycle 24. http://science.nasa.gov/headlines/y2008/10jan_solarcycle24.htm more images: http://spaceweather.com/submissions/large_image_popup.php?image_name=N.-Hebert-J.-Fairfull-J.-Stetson-solar_092208_41c_1222114293.jpg from N.

Title: Re: NEW SUNSPOT! Post by: k4kyv on September 24, 2008, 01:33:58 AM Quote Jan. 10, 2008: Hang on to your cell phone, a new solar cycle has just begun. "On January 4, 2008, a reversed-polarity sunspot appeared—and this signals the start of Solar Cycle 24," says David Hathaway of the Marshall Space Flight Center. This is the second one in 8 months thought to belong to Cycle 24. But I'm not getting my hopes up just yet. We'll have to wait to see how this plays out. 160 and 75m DX should be good this coming fall and winter. http://science.nasa.gov/headlines/y2008/23sep_solarwind.htm http://www.msnbc.msn.com/id/26857491/ Title: Re: NEW SUNSPOT!

Title: Re: NEW SUNSPOT! Post by: k4kyv on September 25, 2008, 12:07:18 AM But condx on 160 will be better during the minimum. So will 75 for DX, but the band may go long early in the evening making it useless for normal 75m activity.

Unfortunatley, 160's been pretty noisy for me these past few weeks. AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
