Hi MF

TA conditions favouring low latitudes again ?
I was the only one spotted last night

Sorry, can not copy the spots here. Saw them once but now WSPR server = looks out of order again :(

Alan, Stefan & All: The LF T/A dx = event did coincide with or just after a C-class X-ray flux event of mo= derate duration (30 minutes or so).  It was a lower level C-class even= t in the C2 or C3 range.  Perhaps the combination of the X-ray flux event and geomagnetic state are involved in the propagat= ion enhancement. 
 
Also interesting that the resulting T/= A dx event was farther to the south in the U.S. Perhaps some seasonal cycli= c factor is involved as well.   I was surprised that neither WG2XJM, W= G2XKA, W1VD, or W1TAG reported any T/A in that time period, although VD and TAG may not have been on the air at the = time.  To the west I have not had any captures from WH2XCR in the= last week or so, although other stations farther south of my location have= captured XCR recently and XJM has done so with his large RX antenna arrays.  If there is a seasonal-latitude pr= obability factor in addition to the X-ray flux and geomagnetic states, then= I would expect better chances of T/A events in the coming months  of = Febuary and March of this year for my inland location.

Thanks Stefan. MMmmm interesting......= the DST was stable at around -50nT and did not dip further on the CME = on the 21st it was slightly above the value early morning on the 20th. The = precipitation is at high latitudes and does, it is thought, take a little while to diffuse to lower latitudes. Again th= e Dst is the "pressure" behind the electron injection it is not r= elated to the concentration of hot (excess absorbing) electrons in the= ionosphere.
 
Thanks for your test, it adds to the s= uggestion that Dst below -20nT can affect your signal propagation.
