| Zusammenfassung |
| For a period of a few hours, the penetration of electric fields of solar
wind origin is at its highest efficiency. In November 2003, five days of
continuous vertical drift data were obtained at the Jicamarca Radio
Observatory. Here we have isolated a range of frequencies centered at a
few-hour period for a five-day period and have explored the local time
dependence of the penetration, along with the time delay due to
magnetospheric effects. We find that the latter ranges from 15 to 25 min.
For the local time dependence, we find that the period of
anti-correlation is roughly from 21:00 to 04:00 LT, with positive correlation at
other local times. |
