We installed solar panels and digital meteorological equipments whose electrical power is supplied using PV on July 13, 2011. Then, the relationship between the electric power generation and the irradiation, air temperature, and wind velocity was investigated on a roof at a university. The electrical power generation, irradiation, air temperature, and wind velocity were monitored over two years...

A method for the full three-dimensional (3-D) reconstruction of the trajectories of coronal mass ejections (CMEs) using Solar TErrestrial Relations Observatory (STEREO) data is presented. Four CMEs that were simultaneously observed by the inner and outer coronagraphs (COR1 and 2) of the Ahead and Behind STEREO satellites were analysed. These observations were used to derive CME trajectories in ...

We present in this Letter the first coordinated radio occultation measurements and ultraviolet observations of the inner corona below 5.5 Rs, obtained during the Galileo solar conjunction in January 1997, to establish the origin of the slow solar wind. Limits on the flow speed are derived from the Doppler dimming of the resonantly scattered component of the oxygen 1032 Å and 1037 Å lines as mea...

The Earth’s magnetosheath, the transition region between the Earth’s magnetopause and the bow shock, is a space laboratory for the investigation of magnetoactive plasmas. Analogeous studies are also the aim of the LAPLAS experiment planned for the FAIR facility at GSI [1]. One of the recent problems of the magnetosheath physics is the dependence of its plasma depletion layer on the direction of...

Velocity and magnetic field fluctuations in the solar wind show evidence that non-linear turbulent dynamics are present in the interplanetary medium. The cascade of energy created by these turbulent processes may provide a mechanism for in situ heating of the solar wind plasma. We perform three studies analyzing the turbulent energy cascade at 1AU using 10 years of data from the Advanced Compos...

Circumterrestrial Lyman-α column brightness observations above 3 Earth radii (Re) have been used to derive separate 3-D neutral hydrogen density models of the Earth’s exosphere for solar minimum (2008, 2010) and near-solarmaximum (2012) conditions. The data used were measured by Lyman-α detectors (LAD1/2) onboard each of the TWINS satellites from very different orbital positions with respect to...

We present a three-dimensional numerical model for the generation and evolution of the magnetic field in the solar convection zone, in which sunspots are produced and contribute to the cyclic reversal of the large-scale magnetic field. We then assess the impact of this dynamo-generated field on the structure of the solar corona and solar wind. This model solves the induction equation in which t...

The observational rate of mirror mode waves in Venus’s magnetosheath for solar maximum conditions is studied and compared with previous results for solar minimum conditions. It is found that the number of mirror mode events is approximately 14 % higher for solar maximum than for solar minimum. A possible cause is the increase in solar UV radiation, ionizing more neutrals from Venus’s exosphere ...

Paper deals with involvement of external meteorological influences on the shape of Heat Supply Daily Diagram (HSDD), such as air temperature, wind velocity, wind direction, exposure (intensity of solar radiation), air humidity and air pressure. Inclusion of these weather influences results in improvement of HSDD forecast.

An empirical model for forecasting solar wind speed related geomagnetic events is presented here. The model is based on the estimated location and size of solar coronal holes. This method differs from models that are based on photospheric magnetograms (e.g., Wang-Sheeley model) to estimate the open field line configuration. Rather than requiring the use of a full magnetic synoptic map, the meth...
