Two Juliusruh ionograms for the disturbed evening hours on 08th September 2017. Both ionograms came out with wrong autoscaling results and derived electron density profiles but are able to be manually scaled with reasonable results. – The upper ionogram (17:53UT) shows a) spread echoes between ~3 and >4MHz, which corresponds to a Frequency Spread parameter FF ~1MHz and b) non-vertical or oblique echoes (>15° off-zenith) marked as coming from south directions (see right color legend).
