1. LF: strange MF TA propagation last night (score: 1)

I just noticed very strange TA propagation on MF last night: During a very short period (04:40 - 05:02) 3 US stations were copied in southern Germany, but nowhere else in Europe: 2016-03-07 04:40 WH2

Wow, very impressive. As we saw in the past, JN68 is a special field... The dst plot showed a dramatical dip. On LF we think that propagation must be down for days but on MF i thought there can be mi

Hi Stefan, all, to get the facts right: there were many other EU's "listening" at that time (> 30), but any one (you) at less than 500 km from the JN68 group. So it's not sure how focussed the propag

Hi Rik, thanks for obeservations and for evaluating the somewhat mysterious propagation on MW into JN68. There were other nights when even DH5RAE and DL0ABR didn't spot TA stations and I was the only

Hi Rik I looked at your initial posting and the first thing I noticed was the Pacific DX was all before the CME impact and conditions re Dst were good. I have pondered the use of WSPR for propagation

Hello Clemens, Attached is the my Linrad overnight graph of VO1NA on 477.7 kHz. The path was still there, but is certainly effected. There was a lot of static snow, which explains the high background

Hello Alan, thanks for your reply. I was just wondering if (and how) the strange propagation was correlated to the solar events. Although the WSPR SNR values have to be interpreted the sharp eak at 0

Hi Rik yes odd, I do not know how reliable the SNR are because they are a calculated value and probably assuming Gausian noise which LF noise rarely actually is. Being a cynical ol' guy, I suspect a

Hi Rik That is a good run of data but look at the spot times, or rather the intervals between them, 58 mins at the start. OK that may be the path opening, but there are spot intervals between 4 and 1

Hi John if there is that much data on the path it would be worth gathering together and looking at. Individual spots are not too interesting, multiple spots from one station are more interesting but
