Geomagnetism during solar cycle 23: Characteristics
On the basis of more than 48 years of morphological analysis of yearly and monthly values of the sunspot number, the aa index, the solar wind speed and interplanetary magnetic field, we point out the particularities of geomagnetic activity during the period 1996-2009. We especially investigate the last cycle 23 and the long minimum which followed it. During this period, the lowest values of the...
متن کاملStudy of the Geoeffectiveness of Halo CMEs in different phases of solar activity cycle 23
3 Department of Physics, Govt. New Science College, Rewa, (M.P.), 486001, INDIA; __________________________________________________________________________________________ Abstract: Based on SOHO/LASCO catalogue and solar geophysical data, we studied the geoeffectiveness, solar source and flare association of a set of 397 halo CMEs during the period of 1996 to 2008. We find that Disk halos are ...
متن کاملSolar origins of solar wind properties during the cycle 23 solar minimum and rising phase of cycle 24
The solar wind was originally envisioned using a simple dipolar corona/polar coronal hole sources picture, but modern observations and models, together with the recent unusual solar cycle minimum, have demonstrated the limitations of this picture. The solar surface fields in both polar and low-to-mid-latitude active region zones routinely produce coronal magnetic fields and related solar wind s...
متن کاملNorth - South Distribution of Solar Flares during Cycle 23
In this paper, we investigate the spatial distribution of solar flares in the northern and southern hemisphere of the Sun that occurred during the period 1996 to 2003. This period of investigation includes the ascending phase, the maximum and part of descending phase of solar cycle 23. It is revealed that the flare activity during this cycle is low compared to previous solar cycle, indicating t...
متن کاملSolar rotation rate and its gradients during cycle 23
Available helioseismic data now span almost the entire solar activity cycle 23 making it possible to study solar-cycle related changes of the solar rotation rate in detail. In this paper we study how the solar rotation rate, in particular, the zonal flows change with time. In addition to the zonal flows that show a well known pattern in the solar convection zone, we also study changes in the ra...
