Comparison of the times of occurrence of a newly discovered type of disturbance in the interplanetary magnetic field at 0.72 astronomical unit with the passage of the small Venus-crossing asteroid, 2201 Oljato, reveals a possible association, but the source of these disturbances appears to be associated with outgassing material in the Oljato orbit some distance behind the asteroid and not with the asteroid itself. This suggested association can account for one quarter of the total number of… Expand

Abstract A new class of interplanetary magnetic disturbance has been identified which consists of a nearly symmetric rise and fall of the magnetic field surrounding a cusp-shaped maximum. TheseExpand

Abstract A class of unusual magnetic disturbances has been discovered in which the interplanetary magnetic field increases to a sharp maximum and then decreases almost symmetrically. Initially theseExpand

Interplanetary Field Enhancements: Observations from 0.3 AU to 1 AU
Interplanetary Field Enhancements are rare but very distinct increases in the magnetic field strength, reaching a nearly symmetric cusp‐shaped peak. These increases are usually accompanied by a thinExpand

Strong interplanetary field enhancements at Ulysses—evidence of dust trails' interaction with the solar wind?
Interplanetary field enhancements were first discovered in the vicinity of Venus. These events are characterised by an increase in the magnitude of the heliospheric magnetic field with aExpand

Interplanetary field enhancements travel at the solar wind speed
[1] Interplanetary Field Enhancements (IFEs) are cusp-shaped increases and decreases in the interplanetary field, accompanied by a thin current sheet. They can last many hours and even the strongestExpand
