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.

The sun has been increasing its activities substantially over the past weeks. M- and small X-flares have been occurring frequently. On November 2nd region 12891 produced a flare with an accompanying CME, which reached Earth after 40 hours. It caused major and even severe storm conditions, but as the Bz component of the plasma field did not really turn south, the aurora did not reach very southern latitudes. Alas!

Comment:
2 M-class flares (M1.7 and M1.5) that mixed up caused a strong aurora, reaching G3 level and creating visible aurora as far south as California.
The storm started on november 3 around 22utc and subsided on november 4 around 14 utc.
For West-Europe the aurora started too late, and too far to the west, so it was not possible to take full advantage of it.
Lack of activety during this period didn't help too.
Stations further east (UA3-4-9) and north (SM2-3-4/OH) where able to catch a bit more.
Here in JO32je the aurora became usuable between about 11.30-13.30utc, with some weaker aurora signals.
