Reported May 13, 2019 brightening of Sgr A* declined at flare emission time, as strong coherence between IMF and geomagnetic indices also declined, and has further correlations with phases and waveforms:

This must be explained. Do et al. 2019 Keck observations coincide w/#LIGO-virgo. ALL of such observations precede the NIR brightening stage for Sgr A*. Stars and Sgr A* in Keck images have doubled, round "halos" that resemble IR hotspots or aliasing.

#LIGO-Virgo #S190513bm trigger, 20:54:28 UTC; #Keck #SgrA* N-IR obs. interval (10:20-14:30 UTC); 2019-0513 Honolulu (HON) magnetometer ||N||, ||E||, ||Z||, ||F||
Position lock attained w/out sufficient floor sample time; extinctive flux/gas interference associated var. with galaxy-scale/interplanetary/local foreground affects entire FOV for duration of event. The interval is quasiperiodic, self-affine, and coherent from ~8:30-14:30 UT:


More woes for systematic error for Keck, perched upon seismically active Mauna Kea; Keck contributed to uncontrolled #SgrA "brightening"
science.sciencemag.org/content/368/64 Seismic events magnetically coupled - phase locked - to lower ionosphere contribute to ordered disturbances. Period-doubled scintillation/quasi-nematicity for refractive foreground can be deceptive: #Keck #SgrA* arxiv.org/pdf/1908.01777





The extent of influence of #MagneticFields dynamically-bound and stabilized by extremal surface states of Sgr A* may be trans-galactic, like its gravitational potential, affecting heliospheric gradients/heliopause oscillation https://phys.org/news/2020-06-magnetic-fields-perspective-milky-black.html
These influences may be rigid and even weakly coherent, affecting the eventual many body post-#Keplerian perturbations of orbits of #PlanetarySystems (themselves collectively-modulating feedback that drives sun-like coronas).
The median joint phase of the three fastest stars (S2, S55, and S62) nearest supermassive black hole #SgrA* is virtually identical to the ~11.3 year Schwabe #SolarCycle and its moments are fractionally-equivalent. I found that similar characteristic constants of proportionality emerge:
