Magnetospheric sawtooth event recorded in GOES-13 magnetometer (proton flux) with shock arrival and precipitous flux spike at geostationary orbit calculated to arrive during the few minutes surrounding GW170817. This delay between magnetometer peak and GW170817 signal arrival is 37.9 minutes, ± 3 min; standard feedback-modulated/stabilized lags for the Northern Hemisphere are coincidentally identical with certain multi-phase quasiperiodic particle injection minimum arrival lags from magnetosphere bow shock ahead of magnetopause, with approx 3-5 minute delay added to 30-40 minute terrestrial polar magnetosphere-ionosphere propagation preceding coherent geomagnetic coupling response, related to variable solar wind density and speed https://scholars.unh.edu/cgi/viewcontent.cgi?referer=https://www.google.com/&httpsredir=1&article=1243&context=physics_facpub, https://encompass.eku.edu/cgi/viewcontent.cgi?article=1000&context=ugra, https://www.ann-geophys.net/36/205/2018/angeo-36-205-2018.pdf, https://scholars.unh.edu/cgi/viewcontent.cgi?article=1238&context=physics_facpub, https://www.sciencedirect.com/science/article/pii/S0964274902802128http://www.iwf.oeaw.ac.at/fileadmin/publications/mag_tail/keika_et_at_JGR_2008b.pdf ); its transient response function is potentially associated with long or multiple (distributed) TGFs from TGEs (or a potentially unknown kind of magnetospheric hard x-ray burst, if not itself the arrival of a delayed particle flux from a CME), which fits spectral calibrations much better than a weak, off-axis GRB from a kilonova in NGC 4993.

Solar elevation difference from 90° during the GW170817 event with respect to dual messenger co-localization centroid between Tanzania and Madagascar is identical to the upper limit (28° - the calculated angle of the so-called off-axis short GRB associated with GW170817 a short GRB seen off-axis, [1710.06421] Off-Axis Emission of Short GRB Jets from Double Neutron Star Mergers and GRB 170817A), and this radius is significant, given the near-solar sky localization for NGC 4993. The lower solar elevation deviation bound from linked publications (16°) is the solar elevation deviation from the Northern bound (Horn of Africa) with identical longitude for the Fermi-Integral and first LIGO-VIRGO sky localization with respect to the final SL centroid longitude (see small thunderstorms in general region, showing discharge synchronzed with global magnetospheric-ionospheric modes). The mean differential angle I calculated from the five relevant coordinates (E boundary of joint GW/GRB sky localization area, W boundary, VIRGO, LIGO Livingston, and LIGO Hanford is 24.2° (differentials from right orthogonality not treated like circular quantitites, although they imply a circular horizon):

North American ground magnetometer data (SuperMAG, link to data) for September 14, 2015 UTC - the day LIGO detected gravitational wave transient GW150914 - quite plainly responding to a critical event with parametric crossover and cross-correlated phase-peak-coupling, among other unusual traits that are also found in solar wind/magnetospheric/lightning data on this day.
The peak of the event in the N component is surrounded by 41-51 minutes of phase-locked global lightning with a period of 5-minutes (correlated with exact LIGO noise window and both ACE and GOES solar wind, IMF, and proton flux as well, with an expected CME arrival and one of the most spectacular Earth-facing coronal holes in a solar cycle, accompanied by a second open (polar) hole with more than 35% of the visible coronal surface open magnetically toward Earth).

A very clearly-defined and ordered sawtooth particle injection with three stationary asymmetric peaks is transferred as a time symmetry-breaking, propagating transverse-bound double-well potential signaled by the appearance of multiscaled and recursive double wells and double peaks as quasiperiodic time reversal symmetry breaking prevails, the result of push-pull crossover.
Such an unusual substorm transition evolved over the majority of this single day, gradually generating both excess charge and impulsive field transients - possible sources of signals prematurely hailed as gravitational waves. The autocorrelations of both time and spectral data from this (and all others, it seems) GW event embeds and covaries in both time and frequency domain with high confidence into the same asymmetric groupoid flow transformations - with the same eigenvalues and cumulative correlations - from solar wind and IMF data (see earlier posts for some examples of such unfortunate identity between a non-astrophysical explanatory source and LIGO GW). The appearance of significant non-Gaussian signal information, phase-locked and irrationally-fractional, in so many non-astrophysical data sources - virtually identical to the signals LIGO is insisting are GW - is not a coincidence, I think I am able to propose. The remainder of the individual station plots follow the standardized compilations, as included below, in this link to plots of individual North American ground stations.

Global and Continent-wide  Blitzortung.org lightning ground flash data - as GIFs - for each of the seven LIGO-VIRGO gravitational wave transient detection periods (embedded into this article - scroll below), with global lightning for the same period and data source, showing very clearly the previously-known (but as yet enigmatic) effect of ionospheric-magnetospheric coupling with lightning trigger driving during sawtooth injection events, which occur, averaged for solar cycle 23 (data are scant; solar cycle 23 in its entirety is the only period available, but cycle 24 ends this year) 11 times annually. From September 14, 2015 to the end of August 2017 as LIGO operated (with an inoperative stage during most of 2016), evidence for both sawtooth injection events and such unusual lightning activity coincide during each GW detection. Prior peer-reviewed studies have identified properties of the magnetic components of Schumann resonances as problematic detector error sources that have prevented the study of a stochastic GW background.

     A peculiar discharge count trend for five-minute (5[3,2]) impulse triggers (global-coherent [non-random] two-phase duty cycle) terminating through bursts of near-simultaneous ground discharge follows quiet periods of approx. 2-3 minutes prior, conforming to the mean length equal to stated and well-recognized correlated cycle lengths from prior analyses (see On the time lags of the LIGO signals); high SNR strain data are seemingly phase and amplitude locked between detectors during these periods. It is not well-known or considered during hypothesis development and testing that [ground strike] lightning can [near] simultaneously respond with stable phase coupling to high-resolution geomagnetic, ionospheric, and magnetospheric data during these unusual global discharge correlations, bound to near-exact 2, 3, and 5-minute increments. Geographic correlations between active regions on Earth also occur during these correlated impulse-locked phases, especially between Central-Eastern North America and Southern Australia.


Solar wind phase and amplitude locking between noise correlation phases during GW150914 and LVT151012 show exact data gaps as well, which is not an artifact of data processing. Gaps in ACE or GOES satellite data indicate excessive charging has occurred or the fidelity of the data have been rejected during post-processing before distribution. The pulse periodicity in the global lightning activity around GW trigger times is represented as vertical bars, to familiarize the reader with the extended significance of such unusual lightning impulse/trigger behavior:
