Daily Summary of COMP data for March 13, 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: small, dark coronal cavity
  • CORONAL CAVITY (NE limb) observed by CoMP: coronal cavity visible in intensity, velocity and L/I
  • CORONAL CAVITY (SE limb) observed by KCor: large coronal cavity
  • CORONAL CAVITY (SE limb) observed by CoMP: coronal cavity visible in intensity and velocity
  • CORONAL MASS EJECTION (W-SW limb) observed by KCor at 1746 - 2136 UT: slow CME in progress appears as a dark tall coronal cavity moving outward also seen in SDO 171
  • ACTIVE PROMINENCE/SURGE (W limb) observed by CoMP: visible in HeI 1083nm
  • PROMINENCE ERUPTION (W-NW limb) observed by CoMP at 2010 - 2022 UT: large prominence eruption seen in HeI 1083nm
  • CORONAL MASS EJECTION (W-NW limb) observed by KCor at 2024 - 2041 UT: faster CME with with front visible in a few frames, best seen in non-filtered images, very noisy data, corresponds to a LASCO CME
  • CORONAL CAVITY (NW limb) observed by KCor: small, dark coronal cavity
  • CORONAL CAVITY (NW limb) observed by CoMP: dark coronal cavity visible in intensity, velocity and L/I

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.
343 1074nm images available

46 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
