Daily Summary of COMP data for May 6, 2017

Event(s) on this observation date:
(culled from the 2017 event table; a green triangle indicates downloadable movies of the event)
  • JET/POSSIBLE CORONAL MASS EJECTION (E limb) observed by KCor at 1704 - 1744 UT: very narrow jet/possible cme,likely part of the outflow following the CME at this location before the start of the MLSO observing day
  • CORONAL CAVITY (SE limb) observed by CoMP: elongated coronal cavity visible in intensity and velocity
  • CORONAL MASS EJECTION (NW limb) observed by KCor at 1658 - 1826 UT: thin loop moving outward, no clear CME in LASCO but slow erupting cavity seen in SDO
  • CORONAL CAVITY/PSEUDO-STREAMER (NW limb) observed by CoMP: small coronal cavities under a pseudo-streamer
  • ACTIVE PROMINENCE (NW limb) observed by CoMP: small active prominence noticeable in HeI

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.
717 1074nm images available

54 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
