Daily Summary of KCOR data for April 1, 2017

Event(s) on this observation date:
(culled from the 2017 event table; a green triangle indicates downloadable movies of the event)
  • CORONAL CAVITY (NE limb) observed by CoMP
  • ACTIVE PROMINENCE (E-NE limb) observed by CoMP: large, very active prominence visible in HeI 1083nm
  • ACTIVE PROMINENCE (W-SW limb) observed by CoMP: large, very active prominence visible in HeI 1083nm
  • CORONAL MASS EJECTION (NW limb) observed by KCor at 1944 - 2028 UT: relatively faint and wide CME with round front
  • CORONAL MASS EJECTION (NW limb) observed by CoMP at 1839 - 2000 UT: noticeable in intensity, velocity and line width as loops outward motion, also seen by LASCO, corresponds to a large AR flare in the NW

K-Cor White Light Coronagraph

Currently, FITS are available in Level 1 only; Fully calibrated Level 2 data will be available at a later date.
Field-of-View: 1.05 to 3.00 Rsun, Spatial resolution: 11.3 arcsec (5.643 arcsec/pix), Cadence: 15 sec
K-Cor White Light Level 1 Data
K-Cor

Level 1 data: FITS images are processed to remove instrumental effects and sky polarization, but intensities are not yet fully calibrated. The GIF images contain a power law scaling.

Full resolution and Low-res cropped GIFs available!
(2, 5, or 10): Movie shows

K-Cor White Light Level 1 normalized radially graded filter (NRGF) Data
K-Cor

Level 1 (nrgf) data: FITS and GIF Level 1 images with a normalized radially graded filter (nrgf, Morgan et al. 2009, adapted by Silvano Fineschi and Sarah Gibson for KCor use) to maximize image contrast. These data are ideal for measuring positions of coronal structures such as CMEs and helmet streamers.

The cadence of these specially processed images is 2 minutes. If you require 15 second cadence, please contact us.
