... but not because of football games in the Champions League with German participation, but because of the solar storm front that rolled up currently on the ground. Timer on X2.2 flare was 15 February at 1:56 UT, which was directed earthward. Such storms are not unusual in the sun and are also practical for their activity. Unfortunately, my many journalists, now riding the wave of panic to have, but this is absolutely no reason. While it may should get one or the other satellite.
Strangely, however, is the message the Chinese of noon today, that the particles of the solar wind there are said to have led to technical failures. How is that when the solar wind at the relevant time barely increased, and (take a value for the speed with which particles of the sun, the earth's magnetic field) of the kp index was only 2? Also in some forums Astro discharged hope that you now by the impact of the particles in this country may see striking auroras, has no chance to materialize in reality. This requires some preconditions. This means the above-kp index at least 5, prefer higher, so that one can even speak of a chance to see the Northern Lights in Germany. Added to this is in addition to the orientation of the magnetic field also known as the auroral oval . This shows the areas where you can at least in principle see the Northern Lights. Currently it is just above the north of Germany, so you could see here if all low on the horizon something if the weather would play for. But the kp value of 1 says absolutely against a visibility in this country.
What makes the evening more exciting, is not the question of whether the VfB Stuttgart loses again, but, when the solar shock front is finally here. This can be any minute now the case. But it is a "but" attached: The later the particles arrive here, the lower their speed and thus the violence with which they strike the ionosphere. Are they relatively quickly, the kp-index increases proportionately. If the slower, is also the value is not particularly high and therefore it decreases the likelihood that you can see auroras in Germany. Since the particle velocity at present (19:56 UT) at 354.5 km / s (which corresponds to the normal solar wind), any hope of auroras here in vain. Current values can be found here , here and here.
Ergo, the longer we wait now, the slower is what is to come and the more likely it is a violent impact. Rather's going to be a harmless and we do not worry about the Northern Lights during the night to make. Nevertheless, a record: even if we do not see auroras, nature is always more exciting than any TV program!
