The Influence of Solar Activity on the Rainfall over India：Cycle-to-Cycle Variations
Solar activity Indian rainfall galactic cosmic rays volcanic or interstellar dust
2009/5/7
We use 130 years data for studying correlative effects due to solar cycle and activity phenomena on the occurrence of rainfall over India. For the period of different solar cycles, we compute the corr...
Analysis of Plasma and Field Conditions during Some Intensely Geoeffective Transient Solar/Interplanetary Disturbances of Solar Cycle 23
Earth:geomagnetic storm Sun:solar and wind magnetosphere coupling
2009/5/7
The problem of solar wind-magnetosphere coupling is investigated for intense geomagnetic storms (Dst γ -100 nT) that occurred during solar cycle 23. For this purpose interplanetary plasma and fie...
Magnetosonic Waveguide Model of Solar Wind Flow Tubes
Solar wind MHD waves magnetic flux tubes
2009/5/7
We consider solar wind flow tubes as a magnetosonic waveguide. Assuming a symmetric expansion in edges of slab-modelled waveguide, we study the propagation characteristics of magnetosonic wave in th...
Study of Microflares through SOXS Mission
X-ray detectors coronal 100 ps solar flares microflares hard X-ray emission
2009/5/7
We present a study of 10 microflares observed in 4-30 keV by SOXS mission simultaneously with Hα observations made at NAOJ, Japan during the interval between February and August 2004. The X-ray a...
The Extreme Solar Activity during October–November 2003
Sunspots rotation flare extreme activity
2009/5/7
The positional measurements of sunspots from the Kodaikanal Observatory and Solar Geophysical data are used to study the association between occurrence of the abnormal activities of big sunspot groups...
Spatial Damping of Linear Compressional Magnetoacoustic Waves in Quiescent Prominences
Sun:prominences oscillations magnetohydrodynamicsradiation:thermal
2009/5/7
We study the spatial damping of magnetoacoustic waves in an unbounded quiescent prominence invoking the technique of MHD seismology. We consider Newtonian radiation in the energy equation and derive a...
The index of scintillation measurement is a good parameter to compare different sites for image quality or 'seeing'™.We have developed a scintillometer, which is deployed on the high resolution...
The electric current separated into two parts reflected the quantative properties of heterogeneity and chirality of magnetic field, and defined them as the shear and twist components of current. We an...
Research Facilities for Solar Astronomy at ARIES
Sun:telescope coelostat solar activity CCD V++
2009/5/7
The solar observational facilities at ARIES (erstwhile U.P. State Observatory, UPSO), Nainital, began in the sixties with the acquisition of two moderate sized (25 cm, f/66 off-axis Skew Cassegrain an...
