The energy utilization of a Photovoltaic (PV) module is determined by the maximum power harnesses from sun. A static PV can only harness sun at particular time in day as revolves. This simply means that if be designed to move such direction sun, then its efficiency will highly improved over period Sun available. design achieved employing Perturb and Observe (P O) algorithm for point tracking (M...

We present an examination of the multi-wavelength observation of a C7.9 flare which occurred on 1998 November 10. This is the first time of imaging observation of the quasi-periodic pulsations (QPPs). Four bursts were observed with the hard X-ray telescope aboard Yohkoh and the Nobeyama Radioheliograph during the impulsive phase of the flare. In the second burst, the hard X-ray and microwave ti...

The small-scale zonal flows in the outer part of the solar convection zone were recently detected by Kosovichev & Schou using f-mode frequency splittings. Results from five 72 day time series (Schou et al.) show a slight drift of the pattern toward the equator in a manner similar to that seen in the so-called torsional oscillation observed using surface Doppler shift measurements. Here I descri...

Two sequences of solar images obtained by the Transition Region and Coronal Explorer in three UV passbands are studied using wavelet and Fourier analysis and compared to the photospheric magnetic flux measured by the Michelson Doppler Interferometer on the Solar Heliospheric Observatory to study wave behaviour in differing magnetic environments. Wavelet periods show deviations from the theoreti...

Recent models of variations of the Sun’s structure with the 11-year activity cycle by Sofia et al. (2005) predict strong non-homologous changes of the radius of subsurface layers, due to subsurface magnetic fields and field-modulated turbulence. According to their best model the changes of the surface radius may be 1000 times larger than those at the depth of 5 Mm. We use f-mode oscillation fre...

Frequency splitting coefficients from Global Oscillation Network Group (GONG) and Michelson Doppler Imager (MDI) observations covering the period 1995–2001 are used to study temporal variations in the solar rotation rate at high latitudes. The torsional oscillation pattern in the Sun is known to penetrate to a depth of about 0.1R⊙ with alternate bands of faster and slower rotating plasma. At lo...

Lepton number charges might be the source of long range forces. If one accepts that neutrinos produced in the Sun do indeed oscillate while crossing the interior of the Sun, then the shift in the phase of the neutrino wavefunction caused by an hypothetical potential associated to the leptonic charge of the electrons in the Sun could affect the oscillation pattern beyond what is actually observe...

The hourly averages of the solar ellipticity measured from June 13 to Sept. 17, 1966, are analyzed for indications of solar oscillations with periods in excess of 2 hr nu < 0.5 hr(-1). Nothing significant is found for frequencies nu > 0.1 hr(-1) but for lower frequencies the power spectrum shows a very complex structure containing about 20 strong narrow peaks. The complexity is illusionary. The...
