Re: (meteorobs) Noctilucent Clouds
Sirko, Thank you very much for the info and pointers to the noctilucent
clouds. Are these the very-thready clouds that one often sees very high in
the sky, or do they only appear from the viewpoint of earth observers when
the sun illuminates them after sunset?
Is there some other connection to meteors other than the common altitude?
This is also the altitude of the lower E-layers; I wonder whether there is a
connection between E-layer radio-reflectivity and the clouds?
Thanks again, Steve Harrison
