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.

Quite a sudden Aurora, not because of the eruption of a solar flare, but due to dissapearing filaments 2 days ago, which triggered a CME.
Amendment: It seems that the aurora was not triggered by a CME, but was due to an exceptionally fast Coronal Hole. http://www.swpc.noaa.gov/today.html

Please be so kind to send us your QSO data, including the antenna bearing. When stations can be matched to one another, the intersections may give a rough idea of the behaviour of the Aurora cloud(s).

Nice opening with very abrupt end, after last QSO SK4MPI/B went from 59A+ to NIL within 5 minutes what is kinda strange. 73, Olli 'BQA

brief little openning - apart from some weak backscatter on some local PA/DL stations nothing else

really nice surprise today, almost nostalgia since last AU-QSO back in 2005.
some really loud stations but not too much activity

As expected, a nice AU-opening about 48 hours after the big ES. Most worked with QTF about 60degrees. A couple of UA3 stations heard too.
