Query: Eruptions from coronal hole bright points: observations and
  non-potential modelling   A single case study of a CBP in an equatorial coronal hole with an
exceptionally large size is investigated to extend our understanding of the
formation of mini-filaments, their destabilisation and the origin of the
eruption triggering the formation of jet-like features recorded in the
extreme-ultraviolet (EUV) and X-ray emission. We aim to explore the nature of
the so-called micro-flares in CBPs associated with jets in coronal holes and
mini coronal mass ejections in the quiet Sun. Co-observations from the
Atmospheric Imaging Assembly (AIA) and Helioseismic Magnetic Imager (HMI) on
board the Solar Dynamics Observatory, and GONG Halpha images are used together
with a Non-Linear Force Free Field (NLFFF) relaxation approach, where the
latter is based on a time series of HMI line-of-sight magnetograms. A
mini-filament (MF) that formed beneath the CBP arcade around 3-4 h before the
eruption is seen in the Halpha and EUV AIA images to lift up and erupt
triggering the formation of an X-ray jet. No significant photospheric magnetic
flux concentration displacement (convergence) is observed and neither is
magnetic flux cancellation between the two main magnetic polarities forming the
CBP in the time period leading to the MF liftoff. The CBP micro-flare is
associated with three flare kernels that formed shortly after the MF liftoff.
No observational signature is found for reconnection beneath the erupting MF.
The applied NLFFF modelling successfully reproduces both the CBP loop complex
as well as the magnetic flux rope that hosts the MF during the build-up to the
eruption.
