The fast stream can be observed in data from the ACE satellite (I provide a snapshot since the on-line plots always update). See the high density (orange) that occurs at the same time that the magnetic field increases (white)? This is an example of a co-rotating interaction region, where the fast solar wind catches up with the slow wind compressing the interplanetary magnetic field. You can see the tail end of the last stream (yellow) that provided so much nice data for us last week (after the noise!).
So plenty of nice radar data tonight as those electrons and protons dive into the atmosphere, ionising as they go. No optics to look at unfortunately. It has been raining persistently for the past few days (wiping out much of the snow). Coupled with the time of year, we have been pretty much in the dark all day; that's generally how we feel when understanding decisions made by STFC come to think of it.
Anyway, STFC and the British government should love us; with the dark and the rain there has been absolutely no blues-skies research going on here for the past few days. Just how they seem to like it.
