Magnetic Cloud and its Interplanetary Shock Sheath as a Modulator of the Cosmic Ray Intensity [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2008
Forbush Decreases (FDs) are representative events of abrupt decrease in galactic cosmic ray intensity. They are known to be strongly associated with solar wind events such as interplanetary shock (IP shock) and magnetic cloud (MC).

Electron dropout echoes induced by interplanetary shock: Van Allen Probes observations

open access: yesGeophysical Research Letters, 2016
On 23 November 2012, a sudden dropout of the relativistic electron flux was observed after an interplanetary shock arrival. The dropout peaks at ∼1 MeV and more than 80% of the electrons disappeared from the drift shell.

Transit of the Interplanetary Shocks Associated with Type II Radio Bursts Within 1AU [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2007
Among the interplanetary shock (IP shock)s observed by ACE spacecraft at 1AU during 1997 to 2000, we have selected 31 IP shocks which had triggered the interplanetary type II radio bursts detected by the WIND spacecraft while those shocks were leaving ...

Physical Characteristics of Coronal Region Driving Out the Interplanetary Shock [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2008
Using the solar wind data of 2000 observed by ACE, We classified the interplanetary shock on basis of shock driver. We examined the physical properties of shock drivers such as the ratio of charge states(O7/O6) and thermal index(I_{th}).

Long-duration high-energy proton events observed by GOES in October 1989 [PDF]

open access: yesAnnales Geophysicae, 1998
We consider the prolonged injection of the high-energy (>10 MeV) protons during the three successive events observed by GOES in October 1989. We apply a solar-rotation-stereoscopy approach to study the injection of the accelerated particles from ...

In situ local shock speed and transit shock speed [PDF]

open access: yesAnnales Geophysicae, 1998
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.

Shock parameter calculations at weak interplanetary shock waves [PDF]

open access: yesAnnales Geophysicae, 2005
A large set of interplanetary shock waves observed using the Ulysses spacecraft is analysed in order to determine their local parameters. For the first time a detailed analysis is extended to the thermodynamic properties of a large number of events ...

Letter to the Editor
Forbush precursory increase and shock-associated particles on 20 October 1989
[PDF]

open access: yesAnnales Geophysicae, 2002
Strong interplanetary disturbances may affect cosmic ray protons tremendously with energies less than 1 GeV, increasing their intensity by hundreds of percents, but they are not so effective for protons of higher energies.
