Aurora

You need to LOGIN to send your report!


Aurora is a phenomena which is most prevalent in the regions close to the so called "Aurora Belt". Depending on where you live in the world this belt may be southern Canada or the northern part of the Nordic countries. In these areas Aurora will occur a dozen times a year, even in the quiet periods of the Solar Cycle. If you live more to the south, like in Central Europe, years may pass with little or no Aurora openings.
 Finally, after a very long solar minimum, our neighbouring star has been showing activity since early 2010. Sunspots have been appearing again, but thus far there have been no major Aurora openings. However, we are interested to have infos about ANY Aurora opening occurring in the European area (other parts of the Northen and Southern hemisphere may be added later, depending on Ham and Solar activity). So if you make any Aurora QSOs on 2 metre or 70 cm, please post them into the aurora page using LOGIN, or send as a text file to pa3biy@mmmonvhf.de and pa2dw@mmmonvhf.de. The results of QSOs will be plotted on a map of Europe, and/or posted as lists of worked stations.

In order to produce an intersection map of the position of the Aurora cloud(s), we need reports from both stations who have been involved in a QSO, including an accurate beam heading. Please use LOGIN (please register), and file your list of QSOs by clicking: "Send your report" and follow the guidelines.

Two CMEs hit the Earth late on June 16th. The impact on the magnetic field was strong (Bz shifted to +40), but the phase wrong: to the North. Hence, only minor Aurora occured on the evening of the 16th. In the course of the night the magnetic field shifted to the South, weakening the Earth's magnetic field and increasing the disturbance. During the morning hours and afternoon Aurora was reported in the Nordic countries, LY, YL, ES and UA. In the late afternoon the Aurora moved a bit more to the South, while the diturbance reached a K of 6. No Aurora was reported over central Europe.
In the Summer the coupling beteen a Plasma bulb (CME) and the Earths magnetic field, is much weaker than in the Spring and Autumn period. Hence: poor Aurora and no Es!
