EUVI Wavelet Images

The full archive of EUVI images, from June 2007 to February 2017, has been wavelet-enhanced and is available in both FITS and PNGs formats. An interface to make access to these images easier is currently under development. In the meantime, you can click here to access the individual images.

Wavelet-Enhanced Images

  • Developer: Dr. G. Stenborg (NRL). See Stenborg et al. (2008) for details or contact Dr. Stenborg.
  • The full STEREO EUVI archive in 4 wavelengths (17.1, 19.5, 28.4, 30.4 nm) is available online.
    • Monthly 2-color movies (17.1/19.5, 28.4/30.4, 171.4/30.4) at 2-hr cadence are available here.
    • The algorithm works equally well for SDO/AIA images. Examples are available in our gallery.
