Daily Summary of KCOR data for April 2, 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 KCor
  • CORONAL CAVITY (SE limb) observed by KCor: large coronal cavity
  • ACTIVE PROMINENCE (W-SW limb) observed by CoMP: large, very active prominence visible in HeI 1083nm
  • CORONAL MASS EJECTION (W-NW limb) observed by CoMP at 1836 - 1851 UT: CME seen as bright round loops moving outward, also visible in velocity and line width, originates from AR in the NW
  • CORONAL MASS EJECTION (W-NW limb) observed by KCor at 1844 - 2020 UT: CME with bright round front, cavity,core
  • CORONAL MASS EJECTION (NW limb) observed by CoMP: wide CME seen as a large dark wave moving outward, also visible in velocity and line width, originates from AR in the NW
  • CORONAL MASS EJECTION (NW limb) observed by KCor at 2032 - 2206 UT: a second, faster CME with bright round front
  • CORONAL CAVITY (NW limb) observed by KCor

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
every Nth image
1307 images available

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.
