Description
This catalog has a list of stream interaction regions (SIR's) observed by STEREO-A and/or STEREO-B between March 2007 and March 2009. For each of the ~145 STEREO A or B observations, the following information is given: event start time, time of the peak pressure, event end time, maximum values of pressure, magnetic field magnitude, proton density and flow speed, and minimum flow speed. It is expected that this list, given in both PDF and Excel formats, will be updated periodically.
