Thanks Jim. Plenty of non IoA to go around.

Good Day all! A VERY light trace of Io-B from my location.? Might be stronger from the west side observatories.

Sabine, Great catches!! Very clear spectrograms, very nice.

In the overall view, a not very spectacular recording of a non-Io-A event. Only at higher magnification interesting criss-cross patterns between Faraday lanes and ?modulation lanes do become apparent.

Yes, but consider that only the 2-element array saw it. That array's beam is fixed at zenith.
The 8-element array saw nothing of it because that larger array has a much smaller beam fixed at azimuth 180°. Its beam elevation is changed every half year or so to match Jupiter's transit elevation.
Sometimes a wide, low-directivity beam is a good thing!

Es precioso de Nancay.

Hi Sabine,
If you had 144 conical log spiral antennas spread over a hectare giving you 26
dBi directivity, you would see that too.? :)
Here are some pictures I took at Nancay in 2016:

For those interested in some of the the details of the Nancay Radio Astronomy Field Station, here is a trip report from my visit there in 2016.
Hope you find it interesting!

What surprises me is that I only saw the initial phase of a Jovian breeze that
Nancay recorded in epic broadness. Jupiter was at negative hour angles at every
point of the event, so one would expect reception conditions to steadily improve.

Quizá por tu comentario acertado sobre las antenas verticales, también compartir que como ingeniero en radio desde hace 50 a?os, he podido investigar y practicar, que muchos de los conceptos y medidas técnicas, tanto en los circuitos electrónicos de radio, amplificación, acoplamiento de impedancias, Balun y un largo etc. no siempre (por no decir casi siempre) corresponden con la realidad práctica en el terreno de aplicación.?
He podido dise?ar, construir y comprobar, que la realidad salta con amplio margen los protocolos teóricos.?
Esto es, por lo que desde mi experiencia he hecho comunicaciones, Radioastronom?a, etc. con grandes resultados, que saltan los conceptos de protocolo técnico. Esto me ha dado siempre grandes alegrías, pues en la Ciencia,? todo es posible de una manera agradablemente? sorprendente...?
Sin más y deseando que tengáis felices e interesantes recepciones, recibid mis más sinceros deseos de digna investigación.
Un abrazo. Claudio? EA4AND?
