Daily Summary of CoMP Data for January 27, 2017

Event(s) on this observation date:
(culled from the 2017 event table; a green triangle indicates downloadable movies of the event)
  • CORONAL CAVITY (NW limb) observed by KCor:
  • CORONAL CAVITY (W and SW limb) observed by KCor: two faint coronal cavities
  • PROMINENCE ERUPTION/POSSIBLE CORONAL MASS EJECTION (NE limb) observed by KCor at 1928 - 0216 UT: slow, faint cavity/prominence eruption, no clear CME, hard to follow towards the end of the observing day because of degrading seeing, corresponds to a small prominence eruption seen in SDO
  • POSSIBLE CORONAL MASS EJECTION (NE limb) observed by CoMP at 1928 - 0216 UT: faint outward motion noticeable in Fe XIII 1074.7nm intensity
  • PROMINENCE ERUPTION (NE limb) observed by CoMP at 1909 - 2037 UT: visible in HeI at 1909-2037UT

Daily Dynamics Archive: Contains all processed level 2 FITS files for the observing day.
In each FITS file there are binary extensions of Peak Intensity, (Edge Enhanced) Peak Intensity, Corrected Line-of-Sight Doppler Velocity, Line Width

Daily Polarization Archive: Contains all processed level 2 FITS files for the observing day.
In each FITS file there are binary extensions of Peak Intensity, (Edge Enhanced) Peak Intensity, Line-Integrated Stokes Q, Line-Integrated Stokes U, Total Linear Polarization Ltot (Ltot= sqrt(Q2 + U2))

Quick Invert FITS contains the results of a simple calculation of linear polarization in the plane-of-sky and magnetic field azimuth (measured positive counter-clockwise from the horizontal). Contains five images: I, Stokes Q and U, linear polarization and azimuth.
