Parker 19th Perihelion Campaign Highlights

During the PSP 19th perihelion, our contributing observatories took observations. We are collecting highlights of these observation here. If you have an observation you would like included, please email us an image with an appropriate caption.

2024-03-30: MLSO K-Cor CME

The Mauna Loa K-Coronagraph observed this CME on March 30, 2024. This CME is accelerating rapidly in the KCor field of view. The last observation was taken at 22:48:09 UT when the CME was at 2.16 solar radii. The best fit to the trajectory was the 2nd order fit which gave an acceleration of 463 +/- 72 m/s2 and a speed of 748 k/s at 2.16 solar radii.

AIA observed a prominence eruption associated with this CME. This CME was also observed by LASCO as a partial halo and shows a deceleration of -2.6 m/s2 in the LASCO field-of-view.

While not ideally aligned with the location of Parker Solar Probe, it is important to identify these large-scale eruptions that can have some impact on outer coronal and solar wind conditions observed at Parker.

These are the first observations from MLSO since Nov 25, 2022. Mauna Loa erupted a few days later and destroyed a significant part of the upper MLSO access road and power lines. Currently the only way to reach the site is by helicopter. Observers and a generator were flown to the site to observe for the Parker Solar Probe perihelion #19. The current schedule for the new road completion is April 2025 – after which MLSO will reopen for nominal observations.
