Daily Summary of COMP data for February 20, 2017

Event(s) on this observation date:
(culled from the 2017 event table; a green triangle indicates downloadable movies of the event)
  • CORONAL MASS EJECTION/PROMINENCE ERUPTION (NE limb) observed by KCor at 1854 - 2016 UT: CME in progress, appears as a prominence/cavity moving outward with no clear front
  • POSSIBLE CORONAL MASS EJECTION (NE limb) observed by CoMP: faint outflow, corresponds to a cavity/prominence eruption in SDO
  • CORONAL CAVITY (SW limb) observed by CoMP: visible in intensity and velocity
  • CORONAL CAVITY (SW limb) observed by KCor: faint coronal cavity
  • ACTIVE PROMINENCE (W limb) observed by CoMP

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.
124 1074nm images available

18 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
