Daily Summary of KCOR data for May 6, 2017

Event(s) on this observation date:
(culled from the 2017 event table; a green triangle indicates downloadable movies of the event)
  • JET/POSSIBLE CORONAL MASS EJECTION (E limb) observed by KCor at 1704 - 1744 UT: very narrow jet/possible cme,likely part of the outflow following the CME at this location before the start of the MLSO observing day
  • CORONAL CAVITY (SE limb) observed by CoMP: elongated coronal cavity visible in intensity and velocity
  • CORONAL MASS EJECTION (NW limb) observed by KCor at 1658 - 1826 UT: thin loop moving outward, no clear CME in LASCO but slow erupting cavity seen in SDO
  • CORONAL CAVITY/PSEUDO-STREAMER (NW limb) observed by CoMP: small coronal cavities under a pseudo-streamer
  • ACTIVE PROMINENCE (NW limb) observed by CoMP: small active prominence noticeable in HeI

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

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

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.
