Daily Summary of COMP data for July 3, 2017

Event(s) on this observation date:
(culled from the 2017 event table; a green triangle indicates downloadable movies of the event)
  • POSSIBLE PROMINENCE ERUPTION (SW limb) observed by CoMP: possible prominence eruption noticeable in HeI 1083nm
  • PROMINENCE ERUPTION/POSSIBLE CORONAL MASS EJECTION (W limb) observed by KCor at 1714 - 1926 UT: possible CME in progress at the beginning of the day, a small bright bubble is ejected, corresponds to a LASCO narrow CME
  • SURGE/POSSIBLE CORONAL MASS EJECTION (W limb) observed by CoMP: outflow from AR at the W limb, early in the day and again after 2244UT, corresponds to surging in SDO
  • ACTIVE PROMINENCE (W-NW and NW limb) observed by CoMP: active prominences visible in HeI 1083nm
  • CORONAL CAVITY (NW limb) observed by CoMP: coronal cavity visible in intensity and velocity
  • 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.
610 1074nm images available

62 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
