The active processes in comets as indicators of physical conditions in the interplanetary space [PDF]
The results of researches of cometary flash activity obtained by authors are generalized. On the basis of this results the new evidences of relation between comets' light curves and level of solar activity are enunciated. A relation of cometary flash activity with heliocentric distances discovered by authors is permit the light curves of comets will be

Predictions of the arrival time of Coronal Mass Ejections at 1AU: an analysis of the causes of errors [PDF]
Three existing models of Interplanetary Coronal Mass Ejection (ICME) transit between the Sun and the Earth are compared to coronagraph and in situ observations: all three models are found to perform with a similar level of accuracy (i.e.

Physics of interplanetary dust capture via impact into organic polymer foams [PDF]
The physics of hypervelocity impacts into foams is of interest because of the possible application to interplanetary dust particle (IDP) capture by spacecraft. We present a model for the phenomena occurring in such impacts into low‐density organic polymer foams.

In situ local shock speed and transit shock speed [PDF]
A useful index for estimating the transit speeds was derived by analyzing interplanetary shock observations. This index is the ratio of the in situ local shock speed and the transit speed; it is 0.6–0.9 for most observed shocks.

What causes the variations of the peak intensity of CIR accelerated energetic ion fluxes? [PDF]
The variation of the peak intensity of energetic ions accelerated at CIR related shocks in the interplanetary medium as observed by instruments on board of ULYSSES during its pass towards the south polar region and from the north polar region back to ...

Magnetic topology of coronal mass ejection events out of the ecliptic: Ulysses/HI-SCALE energetic particle observations [PDF]
Solar energetic particle fluxes (Ee > 38 keV) observed by the ULYSSES/HI-SCALE experiment are utilized as diagnostic tracers of the large-scale structure and topology of the Interplanetary Magnetic Field (IMF) embedded within two well ...

The Physical Nature of Interplanetary Dust as Inferred by Particles Collected at 35 km [PDF]
Particles were collected at an altitude of 35 km by two flights of a volume-sampling micrometeorite collector. The collection scheme is very sensitive and is capable of collecting a significant number of particles. Many of the particles collected have chemical compositions similar to solar or to iron meteorites.

Relating Intermittency and Inverse Cascade to Stochastic Entropy in Solar Wind Turbulence
Turbulent energy transfer in nearly collisionless plasmas can be conceptualized as a scale-to-scale Langevin process. Hence, the statistics of magnetic field fluctuations can be embedded in the framework of stochastic process theory.

Image Encoding With Blipped Gradients in an Echo Train
ABSTRACT Purpose An MRI scanner was designed and built to encode k$$ k $$‐space points in the spin echoes occurring between 180∘$$ 18{0}^{\circ } $$ pulses in an echo train by using blipped B0$$ {B}_0 $$ gradient pulses applied just prior to those spin echoes.
