Daily Summary of COMP 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: a second, faster CME with bright round front
  • CORONAL CAVITY (NW limb) observed by KCor

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.
430 1074nm images available

36 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
