Recent thought on the origin of ULF waves (Kivelson, 2006) has mainly focused on field-line resonances or origin through excitation on the flanks of the magnetosphere and usually under more active solar wind conditions, notably of higher speed.
This method, though simple, proved reliable at both identifying CMEs and picking out the exact time of CME arrival at the ACE satellite, while separating the CMEs from signals resulting from noise or more active solar wind periods.
We find that when the southern solar hemisphere is more active, increasing solar activity in the secular solar cycle results in increasing zonality of the circulation, while when the northern solar hemisphere is more active, increasing solar activity increases meridional circulation.
Japan is getting more active in the solar energy field in recent months, and now, the Japan Aerospace Exploration Agency (JAXA) has revealed a plan under which solar photons will be used to propel satellites in outer space [JP, PDF].
Thus, we can expect our results to highlight the differences between the Sun and more active, but still solar-like stars.
We are trying to get the DNOs to operate on a more active business model but the amount of solar that is projected for 2023 is less than we have today.
On the other hand, small stars tend to be more active than the sun and liable to produce more solar flares and potentially harmful radiation.
Solar has become one of the more active segments in industrial liquidation auctions, said Ross Dove, a managing partner at Heritage Global Partners, which will conduct the Solyndra auction.
Additionally, these materials are more active at 365 nm than at 257.7 nm UV radiation, opening the possibility of using solar light for this application.
The building's solar energy generates her "food"—when she's had lots she's more active, but when her energy levels are low, like in winter when there's less sun, she's less motivated.
But in the solar system's early days, before surface ice evaporated from those bodies, comets were both more numerous and more active (bottom), the researchers contend.
