ABSTRACT The excess speed of coronal mass ejection over the ambient solar wind in interplanetary space generates a highly compressed, heated and turbulent shock-sheath. Here, for the first time, we present in situ observations of a unique and distinct feature of the shock-sheath, which exhibits the characteristics of a planar magnetic structure (PMS) and an Alfvén wave simultaneously. We have used standard techniques to confirm the presence of the PMS as described in Shaikh et al. We have employed the minimum variance analysis technique to estimate the properties of the PMS. The Walén test is used to confirm the presence of the Alfvén wave. Our study unambiguously proves the coexistence of the Alfvén wave and the PMS in the shock-sheath region. Further studies are essential to investigate the origin of such a peculiar shock-sheath and its effect on our view of solar-terrestrial physics.

AbstractWe have investigated the case of a coronal mass ejection that was eroded by the fast wind of a coronal hole in the interplanetary medium. When a solar ejection takes place close to a coronal hole, the flux rope magnetic topology of the coronal mass ejection (CME) may become misshapen at 1 AU as a result of the interaction. Detailed analysis of this event reveals erosion of the interplanetary coronal mass ejection (ICME) magnetic field. In this communication, we study the photospheric magnetic roots of the coronal hole and the coronal mass ejection area with HMI/SDO magnetograms to define their magnetic characteristics.

ABSTRACT Generally, interplanetary coronal mass ejection (ICME) triggers intense and strong geomagnetic storms. It has been established that the ICME sheath-moulded planar magnetic structure enhances the amplitude of the storms. Alfvén waves embedded in ICME magnetic clouds or high solar streams including corotating interacting regions (CIRs) in turn extend the recovery phase of the storm. Here, we investigate a geomagnetic storm with a very complex temporal profile with multiple decreasing and recovery phases. We examine the role of planar magnetic structure (PMS) and Alfvén waves in the various phases of the storm. We find that fast decrease and fast recovery phases are evident during transit of PMS regions, whereas a slight decrease or recovery is found during the transit of regions embedded with Alfvénic fluctuations.
