New blog site under construction

2010-12-22T10:24:00.003Z

I am soon releasing a new site. The content will be more on automatically updating graphics. I do apologise the lack of time to make further "specific analyses" and updates on past propagation event. Let´s see how it goes. Thanks for all viewers so far.

Merry Christmas and Best of 2011 to all!

Jukka

ps. For Nordic medium wave Dxers looking at TA signals, indeces are falling promisingly prior to Christmas Eve. Next opportunity window expected also around new year. Please follow NOAA 3-day forecast and Spaceweather.com to be on track of latest events.

Solar wind velocity (km/s, L1) and planetary K index. Data provided by SWENET.Editor´s note; top dates for good transatlantic DX conditions for MW operated AM stations from NA are marked with grey blocks. Towards the end of the season the number of loggings are getting fewer (people tired on excessive DXs?) but despite that there has been most likely still good openings.

Summer Period

2009-05-07T13:41:00.003+01:00

For next couple of months this blog will turn into a "summer sleeping mode" and most likely only the Gedds estimated Kp index graph will be updated. This is due to the short nights in the northern hemisphere. For example after the 9th of May, the sun is less than 12 degrees below the horizon (term for a dark night) between the sunset and sunrise at Helsinki latitude. Above the 70 degr. North the sun is not setting down at all from 16th of May onwards. The blog will return to normal mode in August.

Hello fellow Dxers! Welcome to my blog pages hopefully for some interesting content and links regarding the wonderful and exiting world of DX listening on medium waves. To start with in the beginning you will find from this page some links and other information for current space weather and geomagnetic conditions. Stay tuned, more will follow.
