On the Triggering of M-Class Solar Flare due to Loop-loop Interaction in AR NOAA 10875
Pankaj Kumar, Abhishek K. Srivastava, B. V. Somov +3
We present multiwavelength analysis of an M7.9 /1N solar flare which occurred on 27 April 2006 in AR NOAA 10875. The flare was triggered due to the interaction of two loop systems.…
Multiwavelength Study on Solar and Interplanetary Origins of the Strongest Geomagnetic Storm of Solar Cycle 23
Pankaj Kumar, P. K. Manoharan, Wahab Uddin
We study the solar sources of an intense geomagnetic storm of solar cycle 23 that occurred on 20 November 2003, based on ground- and space-based multiwavelength observations. The c…
Solar cycle changes of large-scale solar wind structure
P. K. Manoharan
In this paper, I present the results on large-scale evolution of density turbulence of solar wind in the inner heliosphere during 1985 - 2009. At a given distance from the Sun, the…
Peculiar Current Solar-Minimum - Structure of the Heliosphere
P. K. Manoharan
In this paper, I review the results of 3-D evolution of the inner heliosphere over the solar cycle #23, based on observations of interplanetary scintillation (IPS) made at 327 MHz…
