Occultation of Venus of June 18th 2007

Line: 17 to 17
 
  1. Venus will have passed through the position of greatest eastern elongation on June 9th, so it will still be far from the Sun and its light will not difficult the observation.
  2. The Moon is new on June 15th, so on 18th it will still be in a light crescent phase: only the 15% of the lunar disc will be illuminated (phase of 0.151). Then, its brightness will not be annoying for observers and photographers.

  With the naked eye, the planet Venus will be seen thanks to the Moon - as we have already said - and to observe the process of occultation by the eclipsed side of our satellite and of reappearance from behind the brighter side will also be possible. There are no excuses - if the sky is clear enough: wherever you will be, just by looking up to the sky you will enjoy the sight of this event!!

  Finally, if you can observe the event in detail with a telescope, you will see something like this:

Dades tècniques: des d'on i quan podrà observar-se?

Les ocultacions són fenòmens astronòmics que, a l'igual que els eclipsis de Sol, només poden observar-se des de determinades franges de la superfície terrestre i la seva aparença és molt diferent si s'observen des de llocs diferents. En aquest cas, podrà observar-se des de determinades zones d'Amèrica del Nord (en ple dia), fins a l'Índia durant la nit, passant per tota Europa - excepte la zona sud-oest de la Penínsual Ibèrica - i l'Orient Mitjà, on també podrà observar-se a plena llum del dia.

Technical data: from where and when it can be observed?

Occultations are astronomical events which, as well as solar eclipses, can only be observed from certain strips of the earth surface and whose appearance changes a lot with position. In this case, it can be observed from certain areas of North America (in broad daylight), to India during the night, passing through the whole Europe - except the southeast of the Iberian Peninsula - and Middle East, where it will also occur in broad daylight.
