Daily Summary of KCOR data for March 13, 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: small, dark coronal cavity
  • CORONAL CAVITY (NE limb) observed by CoMP: coronal cavity visible in intensity, velocity and L/I
  • CORONAL CAVITY (SE limb) observed by KCor: large coronal cavity
  • CORONAL CAVITY (SE limb) observed by CoMP: coronal cavity visible in intensity and velocity
  • CORONAL MASS EJECTION (W-SW limb) observed by KCor at 1746 - 2136 UT: slow CME in progress appears as a dark tall coronal cavity moving outward also seen in SDO 171
  • ACTIVE PROMINENCE/SURGE (W limb) observed by CoMP: visible in HeI 1083nm
  • PROMINENCE ERUPTION (W-NW limb) observed by CoMP at 2010 - 2022 UT: large prominence eruption seen in HeI 1083nm
  • CORONAL MASS EJECTION (W-NW limb) observed by KCor at 2024 - 2041 UT: faster CME with with front visible in a few frames, best seen in non-filtered images, very noisy data, corresponds to a LASCO CME
  • CORONAL CAVITY (NW limb) observed by KCor: small, dark coronal cavity
  • CORONAL CAVITY (NW limb) observed by CoMP: dark coronal cavity visible in intensity, velocity and L/I

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
1050 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.
