How can we enjoy the rain Oriónidas stars? Meteors caused by the remains of comet known Haley found its maximum on 21 October. Today we will discuss how to enjoy the show.
Every year during the month of October, the earth passes through a debris field of a comet. During this time you can see shooting stars in the sky almost every night. But peak reached in the early hours of 21 , where you can see up to 20 meteors per minute during the magnificent rain Oriónidas. Where do they come from? Why do they occur? And much more interesting, how can we see them? Today we talk about this spectacular astronomical event to enjoy it in the best way.
What are Oriónidas
The rain Orionids is named precisely because its presence is usually found under the image of the Orion constellation, easily distinguished by his belt and sheath . Orionids occur because during this time our little planet through a cloud of space dust and debris left by comet known P1 / Haley, who passed through here now for almost 30 years. Orionids rain is not as dense and strong as other known meteor showers (such as the Perseids, summer, for example), but that does not mean it is not spectacular.
The meteors observed during the Orionids often show a yellow light or green and often end up exploding, what makes this shower a beautiful event. In addition, during its peak, which is reached in the early hours of 21, you can see up to 20 meteors per minute in the northern hemisphere and 40 in the southern hemisphere (due to the disposal of waste). However, if the 21 do not have the right opportunity, we can always try to see the phenomenon throughout the week. It will not be hard to capture some meteor despite this rain is more moderate than others.
How to view the meteor shower
As explained, this moderate rain is easily visible from all globe, while especially from the south hemisphere, so that Latin America will have a privileged position. We can consider the following:
Find somewhere without light pollution
The Orionids rain is a rain of meteors a little weaker. Light pollution in this case can be disastrous. Best is to find a point where just the light of the cities on the horizon is appreciated and most stars are visible. This year, 2015, also have A small problem with the moon is that is crescent. At dawn on 21, also was found to half its size, what will the most difficult things.
Check the weather will
This may seem an obvious thing, is precisely one of the points where more people trust. Sometimes excitement or by the oversight, we forgot to check the weather. And after an hour’s drive to the mountain, suddenly, we realize that is cloudy and it will be impossible to see absolutely nothing. So it is worth doing a quick check before doing anything.
Waiting for the right time
The Orionids are at all times of the night. In fact, they are seen from October 7 to November 2 continuously. But of course, to see a significant number of shooting stars and use the experience to expect best. That is none other than the evening of October 21 into the night. The moment you can see shooting stars will from midnight to sunrise . This year 2015 will be particularly so because of the moon, which will begin to fall late in the night, leaving the clear sky
Look to the right place. Orion
The Orionids, as mentioned, have this name because they are often located in a defined position in the constellation Orion. To locate only must look for the known belt “Hunter” , which also have a group of stars forming the “pod”. Once located, the heating, ie the main point from which “arise” meteors is to the left of the constellation. You look radiant will help us locate the area of greatest concentration. If we are in the northern hemisphere, the radiant is at the top (about one shoulder), while in the southern hemisphere will be located to the left of one of the peaks of the skirt.
Nothing to use telescopes
A advice, especially if we are amateurs, is that we should not use or telescopes and other devices to monitor (binoculars, telescopes or similar). Orionids seen with the naked eye and are very fast. Trying to capture with a device so we only get the lose. It is best to lie down and wait quietly.
This is not the only meteor shower
No, it is not. At this time it is also producing the meteor shower of the Taurids, which can be seen in the constellation Taurus. Although hit its peak around November 5. This rain is slower but very bright, so it is not surprising to find some unexpected star. A little later, by the way, we see the Geminids in December. In addition, as a curiosity, the same field left by the P1 / Haley comet debris causes the meteor shower eta Aquarids between April and May. But that is another story that we’ll talk.
