Re: [HCDX] Aurora...or NOT !
France Inter still hanging on RIGHT NOW... I think all this active condx are a joke... May the good DX not let you run away from the sleep !

Solar activity was very low. No flares were observed. The visible disk was spotless. Solar activity is expected to be very low. Geomagnetic field activity ranged from quiet to active levels. ACE solar wind measurements indicated a recurrent coronal hole high-speed stream began early in the summary period. Velocities gradually increased from 305 to 559 km/sec during the period. IMF changes associated with the transition to the high-speed stream included increased Bt (peak 17 nT at 31/Z) and intermittent periods of southward Bz (minimum -16 nT at 31/0131Z). Well all of this is doing little to me; LW are stronger than ever, I got my 2nd best reception of Europe 1 ever and France-162 is quite good too... However, something is happening as 1) Iceland-189 is inexistent tonight (it's a high-latitude path), this being stronger than Europe 1 during the early mornings AND there is (there was a few minutes ago, but they faded) SOME LITTLE enhancement on Latins, Coro-780 got good and listenable, the 1 kW Rebelde outlet on 610 kHz was briefly good instead of the more elusive YVXY, YVSE or the Voz de la Cultura public broadcaster out of Colombia... But, WABC on 770 is also very strong splattering onto Coro with WBBM completly nulled out. I even have taped a nice play with the radio, as I turned it on and off, switching between Coro and Chicago. But, nothing to really get excited about. I begun to get tired of Coro-780 and Barranquilla-760, I would like to log some REGIONAL YVs in the upper 1300s and 1400s, for this Europe would be a better QTHs, because the high angle of short-skip from east coast domestics aren't overwhelming and, correct me if I'm wrong, there are fewer stations in Europe than in the USA and fewer DRM operations than IBOC ones... It is still strange Uruguay and Carúpano, estado Sucre, YV-land are regular on 1470 along with CPN Radio, Lima, Peru, while there are decades since Peru was last logged within the USA, but there are obvious reasons for this, of course... What I can do right now is only wait, auroral condx may be slow to start, but the CME will still going on tomorrow as well... It stay January 1st AND 2nd, so let's try to sleep and wait until tonight (we ARE Januery 2nd) or let's enjoy the not-so-auroral condx and try to scan the LW band which works better when average or above-average high-latitude paths are in progress. A full repport may come tomorrow or if not tomorrow during the week-end. Tomorrow, I hope to show some LW and MW DX to a friend from school... May the good DX be with you !

[HCDX] Aurora and more...
NW7US Propagation Bulletin Update 21 January 2005 - 1945 UTC As I mentioned early on (see my recent bulletins), the X7 flare unleashed a coronal mass ejection. I had reported that it was probable that the CME was directed Earthward. It was. It has hit, today, and we are now seeing a planetary K index (Kp) of 8, with a reading from Boulder at 7. At the time of this bulletin, the Bz is strongly positive, decreasing the full impact on geomagnetic activity. However, we're watching the IMF closely, becuase if it does turn southward, what is already a major/severe geomagnetic storm will increase even more in strength. Of course, the dynamic pressure of this passage is very high, and the speed is over 950 km/s. At the same time, the proton storm is finally ending. Aurora is very possible for North America this evening. Certainly, Aurora is active over Asia/Europe. With a Kp of 8, it is possible that radio propagation via Aurora is in the cards for today/tonight. 73 de Tomas, NW7US (AAR0JA/AAA0WA) : Propagation Editor for CQ, CQ VHF, Popular Communications : : Creator; live propagation center http://prop.hfradio.org/ : : Associate Member of Propagation Studies Committee of RSGB : : US Army Miltary Affiliate Radio Service (MARS) SMD AAA0WA : : 122.93W 47.67N / Brinnon, Washington USA CN87 CW/SSB/DIGI : : Website/software/database design http://newwebmakers.com/ : : 10x56526, FISTS 7055, FISTS NW 57, Lighthouse Society 144 : ---[Start Commercial]- World Radio TV Handbook 2005 is coming out.
