The sunspot cycle no. 24 in relation to long term solar activity variation
The solar minimum between solar cycles 23 and 24 during the period 2007-2009 has been the longest and deepest one at least since for the last 100 years. We suggest that the Sun is going to his next supercenturial minimum. The main aim of this paper is to tell about arguments concerning this statement. They are based on series of studies, which have been provided during the period since 1997 up ...
متن کاملThe shape of the sunspot cycle described by sunspot areas
The temporal behavior of the sunspot cycles 12–22, as described by quarterly mean values of sunspot areas, can be represented by a single function containing only two parameters: the starting time and the amplitude of a cycle. The parameters are determined for the more recent 11 sunspot cycles and examined for any predictable behavior. As a sunspot cycle progresses, the amplitude parameter can ...
متن کاملGps-derived Local Tec Mapping over Peninsula Malaysia during Solar Minimum of Sunspot Cycle 24
The ionosphere is the major contributor of errors in Global Positioning System (GPS), especially during the 11-year sunspot cycle. The incoming 11-year sunspot cycle is expected to peak in 2013. The ionosphere condition is distinctly severe during ionospheric disturbances caused by high solar activity, which raises the question of how will this affect the ionosphere in the equatorial region, es...
متن کاملThe properties of large amplitude whistler mode waves in the magnetosphere: Propagation and relationship with geomagnetic activity
[1] We present results of a study of the characteristics of very large amplitude whistler mode waves inside the terrestrial magnetosphere at radial distances of less than 15 RE using waveform capture data from the Wind spacecraft. We observed 247 whistler mode waves with at least one electric field component (105/247 had ≥80 mV/m peak‐to‐peak amplitudes) and 66 whistler mode waves with at least...
متن کاملOptimization of thermal curing cycle for a large epoxy model
Heat generation in an exothermic reaction during the curing process and low thermal conductivity of the epoxy resin produces high peak temperature and temperature gradients which result in internal and residual stresses, especially in large epoxy samples. In this paper, an optimization algorithm was developed and applied to predict the thermal cure cycle to minimize the temperature peak and the...
