Another nice Io-B arc, on 120703 about 0900 UT Please see the two atachments. The Nancay Decametric Array has 72 conical logarithmic spirals for each circular polarization. Many thanks to the Nancay Decametric Array Team at the Nancay Radio Astronomy Station of Paris Observatory, and Professor Imai Laboratory at Kochi National College of Technology in Japan.
