A powerful tool for browsing quick-look data in solar-terrestrial physics: "Conjunction Event Finder"
Shinohara, Iku; Hasegawa, Hiroshi; Fujimoto, Masaki +4 more
The "Conjunction Event Finder (CEF)" is a Web tool for seamlessly browsing quick-look (QL) data from many different kinds of satellites and ground-based instruments in solar-terrestrial physics. The QL plots are generally scattered all over the world, so that browsing many of them is so far very troublesome and inefficient. Just a simple procedure…
AKARI All Sky Survey: contribution from AGB stars to the far infrared flux from the Milky Way related to point sources outside the Galactic plane
Pollo, Agnieszka; Takeuchi, Tsutomu Tsutomu; Rybka, Piotr
Using data from the FIS AKARI All-Sky Survey, we make a first step towards the estimation of the contribution from Asymptotic Giant Branch (AGB) stars to the far-infrared (FIR) flux from the Milky Way. We estimate the contribution from the AGB, and post-AGB, stars to the total flux generated by point sources outside the Galactic plane. Additionall…
Anisotropy evolution of magnetic field fluctuation through the bow shock
Glassmeier, K. -H.; Narita, Y.
Measurement of energy distributions in the wave vector domain reveals how anisotropy of turbulent magnetic field fluctuations evolves as the solar wind encounters the terrestrial bow shock and the magnetosphere. While fluctuations in the solar wind, the magnetosheath, and the magnetospheric cusp regions are characterized by the perpendicular wave …
The total failures of GPS functioning caused by the powerful solar radio burst on December 13, 2006
Afraimovich, E. L.; Demyanov, V. V.; Smolkov, G. Ya.
We investigated failures in the GPS performance produced by extremely dense solar radio burst fluxes associated with the intense (X3.4 in GOES classification) solar flare and Halo CME recorded by SOHO/LASCO on December 13, 2006. According to substantial experimental evidence, high-precision GPS positioning on the entire sunlit side of the Earth wa…
Latitudinal dependence of the solar wind density derived from remote sensing measurements using interplanetary Lyman α emission from 1999 to 2002
Lallement, Rosine; Taguchi, Makoto; Fukunishi, Hiroshi +3 more
The interplanetary Lyman α backscattered emission is an effective tool for remote sensing of the global structure of the solar wind proton flux. This paper reports an attempt to derive the latitudinal dependence of the solar wind density by combining the interplanetary Lyman α measurements of the Nozomi spacecraft for the period 1999–2002 with the…
Substorm onset dynamics in the magnetotail as derived from joint TC-1 and Cluster data analysis
Wang, H.; Lühr, H.; Ridley, A. J. +1 more
This study investigates two substorm onset events with favorable constellations of spacecraft, TC-1 and Cluster, separated by several Earth radii. The substorms have been identified in both auroral regions. One is believed to be triggered by a northward turning of the interplanetary magnetic field (IMF), while the other occurs under generally sout…
Simultaneous ground-based and satellite observations of Pc5 geomagnetic pulsations: A case study using multipoint measurements
Balogh, A.; Sung, S. -K.; Kim, K. -H. +5 more
Pc5 pulsations with a latitude-independent frequency of ∼2.8 mHz (period ∼6 min) were observed with ground-based magnetometers in the morning sector (0700–1000 local time) from 0730 to 0810 UT, April 29, 2001. The pulsations exhibited an amplitude peak and a ∼180° phase change at ∼67° geomagnetic latitude. A vortex structure of the equivalent iono…
Determination of the magnetic loop configuration of a solar flare
Sakurai, T.; Hanaoka, Y.
Observationally derived three-dimensional magnetic loop structures of solar flares tell us what type of magnetic configurations is actually responsible for the reconnection/energy release in solar flares. So far, the loop configuration has been discussed on a rather schematic basis, because of insufficient data coverage. However, now we have data …
Jovian electron modulations by the solar wind interaction with the magnetosphere
Misawa, H.; Tsuchiya, F.; Morioka, A.
Variations of energetic electrons released from the Jovian magnetosphere are investigated in detail by using data from three spacecraft, Pioneer 10, 11, and Ulysses. Analyses with the three spacecraft data confirmed that the Jovian electrons are modulated by the dynamic pressure of the solar wind at the position of Jupiter. It is also found that t…
