...…system evolves into substorm breakup onset the brightening arc usually develops discrete rays, also called “beads,” pulsating in a wave-like form along the arc (Donovan et al., 2006; Liang et al., 2008; Henderson, 2009; Rae et al., 2010; Kalmoni et al., 2015; Nishimura et al., 2016; Figure 3)....

...It is well known that auroral intensities start to increase exponentially at substorm onset [e.g., Henderson, 2009], and so logically to understand the linkage between ULF wave signatures observed in auroral and magnetic data, it is necessary to study the temporal evolution of both....

...To date, fine-scale structures, such as distinct ray structures (Akasofu 1964) or quasi-periodic series of bright spots or beads (Elphinstone et al. 1995; Henderson 2009; Rae et al. 2010) are not resolved by the MHD model....

...However, fine-scale structures such as a distinct ray structure (Akasofu 1964), a quasi-periodic series of bright spots, or beads (Elphinstone et al. 1995; Henderson 2009; Rae et al. 2010) are not present in the simulation results....

(2009) conclude consistency with the outside-in model, Liang et al. (2008), Donovan et al. (2009 ), Lui et al. (2008a ,b ), Rae et al. (2009a, b), Henderson (2009) infer consistency with the inside-out model....

...Conclusions from Liang et al. (2008), Rae et al. (2009a, b), Henderson (2009) are based entirely on ground observations, which consistently indicate auroral arc brightening as the earliest onset signature, followed by signatures at higher latitude....
