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 Geomagnetic storm that started the Aurora en Aurora E last night, continued this morning. As the Bz had turned south in the course of past night, conditions had turned to normal aurora again. A nice surprise to wake up and hear various stations with 59A!
Meanwhile the M6.5 Eruption of last night did indeed produce another full halo CME, which has a near 100% chance to hit Earth.
As we know now (June 27th) this event triggerd no Aurora as it turned out to be located to much to the west and it did not reach earth. Solarwinds did reach 800 km/sec but was related to an interplanetary shockwave.
