CUTLASS statistics stuff:
IDL plotting routines.
These occurrence statistics are an extension of the "summary point occupancy" figures discussed in Milan et al. (1997). For a complete discussion of the CUTLASS statistics data-base and the locations of the 16 summary points see this reference. Hopefully these statistics will be updated on a regular basis.

Husafell all-sky camera images from 29 September 1998
To interpret the images, imagine lying on your back in a field in Iceland, with your head pointing north (magnetic north, to be exact), looking up at the sky. To your left is east, and to your right is west, with south at your feet. The images are taken with a 180 degree fish-eye lens, so the horizon describes a circle around the periphery of your vision; directly overhead is in the centre of your field of view. This is the format the images are plotted in. One image is shown every two minutes. Time is indicated at the bottom left of each image in the format hhmm UT. Little spots in the images are stars, and larger, darker, and more diffuse regions are the aurora. At first two bands of faint aurora are observed, one to the north, stretching from east to west, and one overhead stretching from NW to SE. Over time the northerly arc moves equatorwards and brightens, before breaking up into several arcs, filling the sky, and pulsating (not observable with this two minute time resolution).
Here are the images, 15 to a page (each page is approximately 500k in size so may take some time to load):
0302-0330 UT, 0332-0400 UT, 0402-0430 UT, 0432-0500 UT.
As the work progresses I might add some radar data here...
Myopic campaign intervals
View Myopic schedule.
View Myopic campaign FAST conjunctions.
The Myopic mode is run on a campaign basis. The most often employed radar for Myopic observations is Iceland East, though recently, simultaneous runs on Iceland East and West have proved very successful. Also, recent campaigns have been conducted in collaboration wih Japanese optical observations from Husafell, Iceland (see above).
View an example of Myopic observations from the two Icelandic radars from 15 Feb 1999, 2200 UT - 16 Feb 1999, 0200 UT. The E region backscatter appears as east-west aligned features at near ranges.
I'll add a list of other interesting intervals here at some point. For now:
15 Feb 1999, 2200 UT - 16 Feb 1999, 0200 UT - Optical comparison with Husafell all-sky camera.
