The International Project for Radio Meteor Observation
The Effect of Solar Flare at the end of October 2003
Report 10/Nov/2003
The large scale solar flare was observed at the end of October 2003. Radio Meteor Observation uses the scattering of VHF radio wave. The scattering causes around E-layer (100km). When the solar shows high activity, Radio Meteor Observation is influenced such as Sporadic-E. In this time, we research wheather something effect by solar flare was caught or not. This page reports this result from worldwide radio data. If you have a quesition, opinion and you can send me your data, please contact us. These data have Copyright (except for reported observers), so, you must not use these contents without a contact.

(3) Aurora Image File (?) by HROFFT
Dave Swan who is UK observer reported some image files which seemed Aurora. He comments that he never seen anything quite this strong on the system. We do not have enough data for decision. Because this figure has a possibility of Intereference and FAI. This figure, however, has also possibility of Aurora. We have to research and collect more observed data. If you find unusual image files, please send to ogawa@nms.gr.jp
