Part of the SECCHI Consortium
Using heliospheric imaging for space weather application
A sequence of six images from February 2011
illustrating the passage of a CME through the combined STEREO-A
COR2, HI-1 and HI-2 field-of-view. The white near horizontal line
denotes the position angle of Earth; the location of Earth
corresponds to the white dot at the intersection of that line with
the near-vertical curve. HI SpaceWeather
The first comprehensive catalogue of CMEs in the heliosphere
Histogram of daily-average rates of HICAT CMEs
detected by (a) STEREO/HI-1A and (b) STEREO/HI-1B compared to
coronal CME rates from (c) STEREO/COR-2A and (d) STEREO/COR-2B
and (e) SOHO/LASCO. Panel f shows the monthly sunspot count
over the same period. HI CME catalogue
