Event(s) on this observation date:
(culled from the 2017 event table; a green triangle indicates downloadable movies of the event)
  • ACTIVE PROMINENCE (NE limb) observed by CoMP: visible in HeI 1083nm
  • ACTIVE PROMINENCE (E-SE limb) observed by CoMP: visible in HeI 1083nm, also seen as a very small dark feature moving outward ion FeXIII at about 1833-1939UT
  • ACTIVE PROMINENCE (E-SE limb) observed by Kcor
  • POSSIBLE CORONAL MASS EJECTION (NW limb) observed by CoMP at 1644 - 1906 UT: very faint wide outflow noticeable in intensity
  • POSSIBLE CORONAL MASS EJECTION (NW limb) observed by KCor at 1804 - 1926 UT: very faint round front moving outward

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.
341 1074nm images available

24 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
