Using detrended fluctuation analysis (DFA) and rescaled range (R/S) analysis, we investigate the scaling properties of EUV intensity fluctuations of low-latitude coronal holes (CHs) and neighboring quiet-Sun (QS) regions in signals obtained with the Solar Dynamics Observatory/Atmospheric Imaging Assembly (SDO/AIA) instrument. Contemporaneous line-of-sight SDO/Helioseismic and Magnetic Imager (HMI) magnetic fields provide a context for the physical environment. We find that the intensity fluctuations in the time series of EUV images present at each spatial point a scaling symmetry over the range ∼20 min to ∼1 hour. Thus we are able to calculate a generalized Hurst exponent and produce image maps, not of physical quantities like intensity or temperature, but of a single dynamical parameter that sums up the statistical nature of the intensity fluctuations at each pixel. In quiet-Sun (QS) regions and in coronal holes (CHs) with magnetic bipoles, the scaling exponent (1.0 < α ≤ 1.5) corresponds to anti-correlated turbulent-like processes. In coronal holes, and in quiet-Sun regions primarily associated with (open) magnetic field of dominant polarity, the generalized exponent (0.5 < α < 1) corresponds to positively-correlated (persistent) processes. We identify a tendency for α ∼ 1 near coronal hole boundaries and in other regions in which open and closed magnetic fields are in proximity. This is a signature of an underlying 1/f type process that is characteristic for self-organized criticality and shot-noise models.

The National Oceanic and Atmospheric Administration (NOAA) Deep Space Climate Observatory (DSCOVR) mission was launched in February 2015 to the 1st Lagrange point (L1), which is located about 1.5 million kilometers from Earth, toward the sun, along the Sun-Earth line. The DSCOVR mission is a NOAA space weather operational mission that provides and sustains the United States' real-time solar wind monitoring capabilities, which are critical to the accuracy and lead time of NOAA's space weather alerts and forecasts. NOAA funded NASA to refurbish the DSCOVR spacecraft and solar wind instruments, develop the command and control portion of the ground segment, and manage the launch and activation of the satellite. The United States Air Force funded and managed the SpaceX Falcon 9 launch services for DSCOVR. On 7 June 2015, DSCOVR reached its final L1 destination, and in late October 2015, after checkout and post-launch testing, NOAA officially took command of the DSCOVR satellite. DSCOVR became the NOAA operational L1 solar wind monitor on
