CANOPUS ASI images (one minute cadence; 557 nm filter) for the late growth phase, early expansive phase of a substorm. The bottom panel is a keogram showing high resolution MSP data from the CANOPUS MSP, also located at Gillam.

Note the spiral at 0332 UT, and well defined north-south structure at 0337 UT. Events such as this illustrate both the limitations and advantages of ground-based optical observations. The advantage is resolution (spatial here, and temporal not here, but easily obtainable). The disadvantage is limitation to spatial scales smaller than ALL relevant substorm phenomena.

Machine Vision – Content Based Image Retrieval

We are exploring automatic classification of images, rapid retrieval of images from large datasets, and determination of motion of auroral forms, all using sophisticated machine vision techniques.

This classification and CBIR exercise reduces each image to a 48 element feature vector.


Data Searching the late growth phase, early expansive phase of a substorm. The bottom panel is a keogram showing high resolution MSP data from the CANOPUS MSP, also located at Gillam.

A classification of 300000 CANOPUS Gillam ASI images yielded these magnetic local time occurrence distributions for arcs, patches and omega bands. This took about 6 hours on a 1.5 GHz pentium. An equivalent manual survey, which yielded the same results, took 4 months of dedicated effort by a student (who miraculously stayed in the field!). This figure from Syrjäsuo and Donovan [Ann. Geophys., in press].


Data Analysis the late growth phase, early expansive phase of a substorm. The bottom panel is a keogram showing high resolution MSP data from the CANOPUS MSP, also located at Gillam.

Other techniques under development include…

Optical Flow – a technique in which two-dimensional velocity distributions are obtained from image sequences [Partamies, Syrjäsuo, Janhunen (FMI), Hiebert].

Tomography – sophisticated technique to infer heights from multiple overlapping fields of view [Jackel, Donovan, Partamies].

Energy Flux Determination – modification Janhunen [2001] method for THEMIS imagers to estimate energy flux [Partamies, Donovan, Janhunen (FMI)].


Data distribution
Data Distribution the late growth phase, early expansive phase of a substorm. The bottom panel is a keogram showing high resolution MSP data from the CANOPUS MSP, also located at Gillam.

Our contribution to distribution of THEMIS data will be carried out through the THEMIS webpage on NORSTAR-WEB.

We will display real time data products as well as housekeeping information vital to keeping downtime to a minimum.

All summary data, summary images, merged thumbnails, as well as tools for accessing the relational database will be publicly accessible (CDF files on our server FTP tree mirrored at UCB).

The “top 60’’ full time and space resolution image data base will be freely accessible to all THEMIS team members.

The complete full time and space resolution image data base will be publicly accessible via temporary passwords that will be granted in response to specific data requests.
