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.

Aurora caused by a middle latitude coronal hole on October 6th. This caused a G3 geomagnetic storm which contained southward Bz (-17,3 nT).
Skies were overcasted but visual polarlights has been seen in northern Italy; however only photographic (more sensible to red light than human eyes).

he came up to 56A, after finishing the QSO he was 59A for 2 min, then
the sigs dropped down.
Heard him again 18:44UTC with 53A and QTF 005, but again the only one
down in HB9 via AU. Funny, cause usually I should hear Coast-DLs or PAs
with these conditions. But glad I could work GM4JJJ because AU has
become so extremely rare down here (ES likewise). 73 de Chris

I heard sm5ef jo79, sm4bdq jp80, sm7gvf jo77, sm6btt, la3bo jo59, la9dfa jp50, es6do ko27, yl2?, oz1bur jo46, oz1bef jo46,
Dan OZ1BEF was last station audible for about 25minutes from 40deg on Aurora. Interesting.
First time i can copy SK4MPI/b on AU :)
Best "beacon" for me is Lars signal SM4IVE booming as always :)
