| Zusammenfassung |
| Intense late-cycle solar activity during October and November 2003 produced
two strong geomagnetic storms: 28 October-5 November 2003 (October) and
19-23 November 2003 (November); both reached intense geomagnetic activity
levels, Kp=9, and Kp=8+, respectively. The October 2003
geomagnetic storm was stronger, but the effects on the Earth's ionosphere in
the mid-latitude European sector were more important during the November 2003
storm. The aim of this paper is to discuss two significant effects observed
on the ionosphere over the mid-latitude European sector produced by the
November 2003 geomagnetic storm, using data from ground ionosonde at Chilton
(51.5° N; 359.4° E), Pruhonice (50.0° N;
14.6° E) and El Arenosillo (37.1° N; 353.3° E),
jointly with GPS data. These effects are the presence of well developed
anomalous storm Es layers observed at latitudes as low as 37° N
and the presence of two thin belts: one having enhanced electron content and
other, depressed electron content. Both reside over the mid-latitude European
evening sector. |
