STEREO/SWAVES and WIND/WAVES 24h SURVEY

The STEREO/SWAVES and WIND/WAVES 24h SURVEY covers the 00-24 UT time range (1pixel/180sec) and zooms are 3 hours long (1pixel/22.5sec).

It is composed of :

  • three spectra from spatials data (A,B and C)
  • a position of CMEs detected by STEREO A and B layered over the spectra (Red and blue triangles)
  • a position of CMEs detected by SOHO in a 24 hours time range (D)

It is available from the STEREO launch on october 2006.

3 spectra

Logarithmic frequency axis.

1) STEREO WAVES A (A)
2) STEREO WAVES B (B)

The spectra from SWAVES A and SWAVES B are placed head to tail.

Coronal Mass Ejections (CMEs) form LASCO (same as Composite I survey but in a 24h time range)

STEREO LASCO CMEs (D)

  • Time of appearance in SOHO/LASCO C2 and direction (arrow)
  • Speed V(First order, km/sec), angular width W(deg)
  • Black: detected in C2 and C3
  • Grey: detected in C2 only

STEREO CMEs (Red and blue triangles)
