A major goal of helioseismology is to understand the mechanism of the solar cycle. In this paper, some results of helioseismic observations relevant to the cycle are briefly reviewed, the current stat...
Solar Cycle Variation of Interplanetary Coronal Mass Ejection Latitudes
Sun activity coronal mass ejections (CMEs)
2010/9/15
With the use of interplanetary coronal mass ejections (ICMEs) compiled by Richardson and Cane from 1996 to 2007 and the associated coronal mass ejections (CMEs) observed by the Large Angle and Spectro...

2010/9/15
A detailed study has been conducted on the long-term changes in the diurnal variation of cosmic rays in terms of high and low amplitude wave trains event (HAEs/LAEs) during the period 1996–2008 (solar...
Sustained drops in the energy output of the Sun could be more common than modern experience suggests, according to an international team of astronomers that has studied the activity of a number of Sun...

Energetic neutral atom fluxes from the heliosheath varying with the activity phase of the solar cycle
Energetic neutral atom fluxes solar cycle
2009/5/27
Energetic neutral atoms (ENA's) which are produced in the heliospheric interface can be used to remotely investigate this highly interesting, but poorly known region acting as buffer against the inter...
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...

Predicting Maximum Sunspot Number in Solar Cycle 24
Sunspot number precursor prediction technique geomagnetic activity index aa
2010/9/15
A few prediction methods have been developed based on the precursor technique which is found to be successful for forecasting the solar activity. Considering the geomagnetic activity aa indices during...
11 April 2007，Astronomers have long known that the Sun’s "activity" rises and falls in cycles that last roughly 11 years each. Now a team of scientists from China and India has developed a theoretical...
