Sporadic E, combining WSPR & VK Logger data

[VK2KRR]

Todays evening south east Sporadic E opening

The Es was at times VERY strong and would have supported 6m, but possibly not landing in areas where there were any stations.

Early 6m VK Logger posts from the ever alert Rob VK1KW (aprox 950 km)-

13-Jun 05:30 VK1KW > VK5RBV in PF95MK on 50.3140 BCN 519 > QF44MT @ 919.8km 271°
there for a minute then gone
13-Jun 05:42 VK1KW > VK5VF in PF95IA on 52.4495 BCN 519 > QF44MT @ 942.3km 268°

You can see that I had -
05:46 DF4PV 28.126080 -18 dB JN49ax 10W VK2KRR QF34mr 16343 Km

13-Jun 05:47 VK1KW > VK5ZPS in PF94FT on 50.1600 SSB 59 > QF44MT @ 961.7km 267°

Then suddenly the EU 10m path was gone for me, and then next thing was an intense signal from VK5ZRL on Es -

10m WSPR

Ive been having a look at some of todays Sporadic E data from WSPR 28 MHz in southern VK.
Looked for someone with a bit of data available, choose transmissions from VK3XPT and recpetion by VK5AKK (655 Km) and VK3MIR (489 Km).
This is what I came up with:

3XPT TX spots

Interesting to see at approx 0450 UTC where the signal became stronger at 3MIR (shorter distance) that it weakened at VK5AKKs longer distance. Could be just a co-incidence though too.

This sort of data could be improved in a co-ordinated group of stations, with some dedicated RX only stations. For example VK5AKK was on RX only today, so he could capture each TX sequence and not have data lost by himself TXing at the same time as VK3XPT. Where as there were some data gaps from VK3MIR due to him also TXing and RXing.
