WSJT-X MSK 144 Meteor Scatter
Posted: Mon Mar 04, 2019 9:51 pm
Hello All,
I am perplexed. Why does meteor scatter works best between about 5AM - 7:30AM DST.
Why does it seem to be enhanced only between these times and best results on 6 meters usually.
A few possibilities come to mind.
Operators are not willing to get up earlier and usually they quit to go off to work by 8AM.
But it is noticeable that the peak in burns are during the above times. But why?
Disregarding the usual periodic peaks as the Earth encounters a stream of dust from comet remains in sun orbit, there will still be a lot of rocks randomly scattered in Sun proximity flooding in from who knows where or left overs?
The Earth is traveling in Sun orbit at 1690km/hour in the direction of earth-sun time 6AM.
At that speed, one would expect that dust and rocks would hit the Earth evenly across it's leading face and spread the reflections over a full 12 hour period but that seems to not be the case. So what is happening?
My guess is Gravity.
All the rocks and dust swept up are heading for the Earth's gravity centre.
That says then the best place for meteor scatter is a circle 2 hours across or 30deg cone. (360/24 15deg/hour) With the dregs dropping off after that. We get the dregs.
Those that don't get effected skip on by with a few impacting at 6PM on the back side or continue on by at a new direction ready to get us next year.
I have not seen a write up about this but my guess is MSK 144 results above and below 35deg Latitude would be poor.
You might think about trying MSK 144 at 6PM to see if there are bits coming around and impacting the atmosphere on the back side too.
So can you point me at the location about some info on all this please? Any ideas please?
Thanks
