[1] Since 1998, the GOES system has made eastward and westward observations of multi-MeV solar proton fluxes. The gyrocenters of the fluxes observed looking westward (eastward) lie outside (inside) geostationary orbit. Due to this "east-west effect," eastward observations of 4.2-82 MeV protons vary with respect to their westward equivalents. At times of high solar wind dynamic pressure (P dyn > 10 nPa), the "inside" and "outside" fluxes are approximately equal. As P dyn decreases to ∼1 nPa and the ring current decreases, the "inside" fluxes decrease as much as an order of magnitude with respect to the "outside" fluxes. Under low P dyn , the "inside" fluxes exhibit short-lived (1-3 hr) increases, sometimes to the levels of the "outside" fluxes, during periods of enhanced AE index activity. This association suggests that magnetotail topologies associated with substorms enhance the access of solar protons to lower L shells under low P dyn . Citation: Rodriguez, J. V., T. G.

“…Starting with GOES 8, the GOES satellites have been threeaxis-stabilized. The EPS on GOES 8-12 has a single, nominally westward field-of-view (FOV) [Onsager et al, 1996]. However, since January 1998, the GOES 10 EPS was directed eastward.…”

“…In particular, for the 28 -30 October 2003 event with ≈ 870 × 10 20 Mx, the Ap index, in accordance with this dependence, should be around 700. This estimate does not contradict the largest variations of the horizontal component of the Earth's magnetic field (about 1700 -2500 nT) registered by high-latitude magnetometers (e.g., Panasyuk et al, 2004). According to the data of the magnetic observatory Moscow (IZMIRAN), in the period 21 -24 UT on 29 October 2003 the field variations were about 1200 nT, that yields Ap ≈ 800.…”

Relationship Between the Magnetic Flux of Solar Eruptions and the Ap Index of Geomagnetic Storms

et al. 2014

Solar coronal mass ejections (CMEs) are the main drivers of the most powerful non-recurrent geomagnetic storms. In the extreme-ultraviolet range, CMEs are accompanied by bright post-eruption arcades and dark dimmings. The analysis of events of Solar Cycle 23 (Chertok et al. in Solar Phys. 282, 175, 2013) revealed that the summarized unsigned magnetic flux in the arcades and dimming regions at the photospheric level, , is significantly related to the intensity (Dst index) of geomagnetic storms. This provides the basis for the earliest diagnostics of geoefficiency of solar eruptions. In the present article, using the same data set, we find that a noticeable correlation also exists between the eruptive magnetic flux, , and another geomagnetic index, Ap. As the magnetic flux increases from some tens to ≈ 500 (in units of 10 20 Mx), the geomagnetic storm intensity measured by the three-hour Ap index increases on average from Ap ≈ 50 to a formal upper limit of 400 (in units of 2 nT). The established relationship shows that the real value of the Ap index is not limited and during the most severe magnetic storms may significantly exceed 400.

“…The solar cycle is just embarking on the upward leg of its cycle, and the next solar cycle high is confidently predicted in 2011-12 (Yermolaev 2004;Odenwald 2008;Panasyuk 2003). Further, there have been widespread and respectable reports that this coming cycle is expected to be about 50% more intensive than the previous cycle.…”

The present work aims to investigate Solar Storming effects on the determination of geodetic coordinates. Preliminary results of an analysis of satellite and ground -based measurements during extremely strong geomagnetic storm on 11th September 2005 are presented. A similar situation was also observed on 30th October 2003 and 8th November 2004. The disturbance of the Sun, solar wind, and magnetosphere during these periods was weaker than during the similar period in 2003 with respect to a number of parameters. Nevertheless, the presented data indicate that the declining phase of solar cycle 23 is one of the most active intervals over the entire period of comprehensive studies of the solar-terrestrial coupling precisely because of the events that occurred in the autumn of 2003 and 2004. Satellite orbit errors and their consequences on the accuracy of ground positioning will also be investigated. It is expected that the results of this research will provide useful conclusions, which will be helpful for a wide range of applications that use Global Navigation Satellite Systems (GNSS) for high accuracy real time measurements. At the same time, this research is expected to be of practical interest for space weather applications as well as for all applications that rely on good real time knowledge of satellite positions.
