Just a word to describe it, gorgeous!

It fascinates me tremendously as a genre but I do not have either instrumentation or capacity;)
Compliments. I would like to deepen the technique, could you suggest something to read? :)

Real sunspots = zero .... now they call them smooth sun spots to soften the pill :-D other than the minimum of Mounder ... and we are down to the apex of the 24th solar cycle ... apart from the 1956 geophysical year Where spot observable sun spots were average over 500 per month, a little less in the 70s with an average of about 430 if I remember well, since then every subsequent cycle has produced fewer spots, ionizing less the layers D and E and F1 of the Our atmosphere, where radio waves bounce back in those layers back to the ground (even 10,000 km), allowing radio long-range radio communications (there were no communications satellites), these rebounds are called skips, and more Layers are ionized by the sun through the emissions generated by solar stains, and they function as a mirror ... up to a certain frequency, then they plunge the layersHigher and lose in space ... Long life in the sun! :-)

Something great and so far I've seen. Vivissime congratulations. If you want and when you can, post a description of the implementation technique. I would be really grateful to you. Hello.

Beppe can you go even better? Beautiful!

Spectacular all over the series ...
Thanks for these pictures.

" Beppe puoi spigare ancora meglio? Bello! "

I miei sono ricordi di oltre 40 anni, la fisica mi è sempre piaciuta Sorriso Il Nostro Sole ha un'interazione col nostro pianeta in una specie di convivenza non troppo tranquilla, la Terra è super fortunata ad avere un campo magnetico sostanzioso in grado di flettere le radiazioni contenute nei flares solari.... Queste emissioni per lo più sono letali per la vita biologica, composte per lo più da raggi Gamma, Raggi X, Protoni e altre particelle che viaggiano quasi alla velocità della luce trasportati dal vento solare. Quando raggiungono il pianeta, questi raggi, vengono deviati dal campo geomagnetico emesso ddl nostra pianeta, generato dal suo nucleo interno, composto principalmente di materia ferrosa. Quando i raggi letali giungono in prossimità della Terra. il campo gravitazionale e il geomagnetismo creano delle forze megnetiche in grado da neutralizzare questi raggi, sospingendoli oltre la magnetosfera facendoli "scivolare" sopra come un impermeabile che protegge dalla pioggia. Si suppone che un tempo Marte avesse una sua atmosfera, ma il suo nucleo piccolo, pare che producesse meno geomagnetismo che, esaurendosi, ha permesso l'atmosfera gassosa marziana di dissolversi nello spazio. Un altro fattore importante è la forza di gravitazione del Sole che tiene in orbita tutto il nostro sistema solare. E' noto che le macchie solari, una volta nei pressi del nostro pianeta, riescono a ionizzare le fascie altre della nostra atmosfera, il primo che se ne accorse fu Guglielmo Marconi, che utilizzò le onde corte per il primo esperimento di comuniocazioni radio transoceanico a bordo della sua nave scientifica Elettra.
Comunque ti rimando al dettaglio, la propagazione ionosferica delle onde radio, che permettono le telecomunicazioni in onde corte. Il link è questo, scritto da radioamatori competenti: www.ariroma.it/docs/projects/propag_ionosferica.pdf

Se invece vuoi vedere l'andamento del Sole attraverso gli osservatori delle sonde SOHO della NOAA-NASA e ora anche ESA, devi andare sul loro sito, dove ogni 12 ore il NOAA rilascia dei bollettini di propagazione in collaborazione con la NASA, che a sua volta pubblica in tempo reale, sia in infrarosso e in Ha, le foto della cromosfera compresi i dati telemetrici della spettrografia solare. ;-)

Thanks to everyone for appreciation. Quietly, I will try to write about the technique used for filming and processing. In the queue: thanks also to Beppe for the information he wanted to share and for the post posted (I have not read it yet but I will do it soon).
