The active processes in comets as indicators of physical conditions in the interplanetary space [PDF]

Astronomical School’s Report, 2000
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

Pulsed flows observed during an interval of prolonged northward IMF [PDF]

, 2005
On the 22 December 2002 the interplanetary magnetic field (IMF) was directed northwards for more than 12h. The Northern and Southern Hemisphere SuperDARN radars were used to study global high-latitude convection during this interval, complemented by data

Observations of the response time of high-latitude ionospheric convection to variations in the interplanetary magnetic field using EISCAT and IMP-8 data [PDF]

, 1999
International audienceWe have combined ~300 h of tristatic measurements of the field-perpendicular F region ionospheric flow measured overhead at Tromsø by the EISCAT UHF radar, with simultaneous IMP-8 measurements of the solar wind and interplanetary ...

Dayside flow bursts and high-latitude reconnection when the IMF is strongly northward [PDF]

, 2006
The characteristics of dayside ionospheric convection are studied using Northern Hemispheric SuperDARN data and DMSP particle and flow observations when the interplanetary magnetic field (IMF) was strongly northward during 13:00–15:00 UT on 2 March 2002.

Observations of interplanetary scintillation during the 1998 Whole Sun Month: a comparison between EISCAT, ORT and Nagoya data [PDF]

Annales Geophysicae, 2000
Observations of interplanetary scintillation (IPS) allow accurate solar wind velocity measurements to be made at all heliographic latitudes and at a range of distances from the Sun.

Interhemispheric observations of the ionospheric signature of tail reconnection during IMF-northward non-substorm intervals [PDF]

, 2005
This paper presents the first interhemispheric radar observations interpreted as the ionospheric response to tail reconnection during IMF-northward non-substorm intervals.

A solar storm observed from the Sun to Venus using the STEREO, Venus Express, and MESSENGER spacecraft [PDF]

, 2009
The suite of SECCHI optical imaging instruments on the STEREO-A spacecraft is used to track a solar storm, consisting of several coronal mass ejections (CMEs) and other coronal loops, as it propagates from the Sun into the heliosphere during May 2007 ...

Physics of interplanetary dust capture via impact into organic polymer foams [PDF]

Journal of Geophysical Research: Planets, 1994
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.

Predictions of the arrival time of Coronal Mass Ejections at 1AU: an analysis of the causes of errors [PDF]

Annales Geophysicae, 2004
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.
