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.

If you are new to VHF DX, you might want to read this small introduction article about Aurora and its relation to the Sun. Other articles related to VHF propagation can be found on the FORUM page.

Finally some aurora again.
An expected CME passed earth and caused the Bz-component of the interplanetatry magnetic field to turn south. A G3 magnetic storm was reached.
You might wonder why there are less QSO-lines on the maps then reported QSO's. For the aurora maps it's important that logs sended are as in the example; like 12:14 PA4EME JO20WX 45: time xx:xx CALL LOCATOR QTF . QSO-lines on aurora maps are only drawn when both stations are sending in a log and the given QTF's are intersecting somewhere in their great circle (which should be in theory the reflecting point). Of course it is still possible to have two different reflecting points or signal paths and the great circles might not intersect.
