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: noticeable in intensity and L/I
  • CORONAL CAVITY (NE limb) observed by KCor
  • POSSIBLE CORONAL MASS EJECTION (E limb) observed by CoMP at 2200 - 0006 UT: visible in FeXIII intensity, appears as a small dark bubble moving outward
  • CORONAL CAVITY (SE limb) observed by KCor
  • SURGE (W limb) observed by CoMP: visible in HeI 1083nm

Coronal Multi-channel Polarimeter (CoMP)

FOV: 1.05 to 1.4 Rsun ; Spatial Resolution: 4.46 arcsec/pixel; Cadence: 5 sec to 1 min.
Simulated CoMP-like data can be generated with the FORWARD Model.
CoMP Intensity
CoMP Intensity
CoMP filtergrams provide calibrated coronal emission intensity in units of millionths of Bsun, where Bsun is the brightness of the solar disk.
666 1074nm images available

48 1079nm images available

CoMP Quick Inversion
CoMP QI sample
Each CoMP Quick Inversion file (one produced per day) includes the line center intensity, linear polarization and magnetic field azimuth. These three images are in one multi-image FITS file, using FITS extensions to hold multiple images (use a fits viewer that can parse these files, such as fv).

CoMP Full Inversion
CoMP Full Inv sample
Each CoMP Full Inversion file (one produced per day) includes the line center intensity, velocity, line width, B field, linear polarization, and azimuth. These six images are in one multi-image FITS file, using FITS extensions to hold multiple images (use a fits viewer that can parse these files, such as fv).
No 1074nm file available

No 1079nm file available
