Event(s) on this observation date:
(culled from the 2017 event table; a green triangle indicates downloadable movies of the event)
  • CORONAL CAVITY (NW limb) observed by KCor
  • CORONAL MASS EJECTION (W limb) observed by CoMP at 2058 - 2128 UT: visible in intensity, velocity and line-width, corresponds to a LASCO/C2 CME originating in the AR near the W limb

  • CORONAL CAVITY (W-SW limb) observed by CoMP: dark, round coronal cavity seen in intensity and velocity
  • CORONAL CAVITY (SW and W-SW limb) observed by KCor: two faint coronal cavities
  • (SE limb) observed by cavity: CoMP
  • CORONAL CAVITY (SE limb) observed by KCor: dark coronal cavity

Daily Dynamics Archive: Contains all processed level 2 FITS files for the observing day.
In each FITS file there are binary extensions of Peak Intensity, (Edge Enhanced) Peak Intensity, Corrected Line-of-Sight Doppler Velocity, Line Width

Daily Polarization Archive: Contains all processed level 2 FITS files for the observing day.
In each FITS file there are binary extensions of Peak Intensity, (Edge Enhanced) Peak Intensity, Line-Integrated Stokes Q, Line-Integrated Stokes U, Total Linear Polarization Ltot (Ltot= sqrt(Q2 + U2))

Quick Invert FITS contains the results of a simple calculation of linear polarization in the plane-of-sky and magnetic field azimuth (measured positive counter-clockwise from the horizontal). Contains five images: I, Stokes Q and U, linear polarization and azimuth.
