The event was not seen in Pune - Overcast sky At about 17:30 IST or 12:00 UT Samir Dhurde and Arvind Paranjpye had wonderful visual (naked eye) sighting of Venus just east of the Moon Dr Vinod Kamble and Arvind Ranade of Vigyan Prasar,
Delhi report that a big crowd had gathered at the
Kshitija Kelkar caught this image of the Moon and
Javeria Aqeel from
Karachi, Pakistan reports that the " The skies were clear, with only a few
passing clouds. Venus disappeared behind the moon around 9:00 PM Pakistan
Standard Time. It reappeared from behind the moon quite close to the
horizon, so I was unable to capture the appearance on camera. The camera
was not capturing it. I filmed the Bhargav Joshi
reports form Vadodara that he only could "recorded it's (Venus') total
disappearance. Some of his images are available at Priyadarshini Bangale from Nanded reports that she and her team we could see the event very clearly using 14" telescope of MGM"S college of engineering, Late Prof. N. C. Rana Observatory. Naveen from
Bangalore Astronomical Society writes that "
I was able to keep track of moon till about little less than 1 deg above
the horizon. Till 9:50 pm, All Photos taken from digital camera with a
tripod, and location : Bangalore." The sky at his location was very
cloudy, hence the photos are grainy.

DrAryeh E Shimron from Jerusalem
says "I was fortunate to have seen moon eclipsing Venus early this
evening above Jerusalem. I could not see Venus before it disappeared
behind the moon but witnessed its reappearance just a few minutes before
the sun set. I am including a few of the photographs presently and will be
in touch again tomorrow with detailed explanations, if you so wish. I am a
retired geologist and a, very much amateur, photographer. " Shimron sends these amazing pictures

On Monday, June 18, 2007, the Moon will come directly between Venus and the Earth. This event is visible close to the sunset at Oman, Jordan, Iran, Pakistan and in the north western parts of India. The map below shows the area
over which the event can be seen. This event takes place after about 15:30 Universal Time (UT), which is very close to GMT. The exact time of the event will depend upon the location of the observer. The occultation timings for various cities of Iran, Pakistan and for Kabul are given in the table below. Mohammad Shawkat Odeh, Islamic Crescents' Observation Project (ICOP), writes that "I'm aware that my friends in -at least- Oman and Jordan will organize public observation for this event. I guess we will do the same here in UAE." Venus is the brightest planet visible from the Earth and can be seen with the naked eyes in the board day light, if one knows were to look for it. This event provides a wonderful opportunity to look for Venus even when the sun is well above the horizon. Venus will be a bit east of the Moon. With the reference of the Moon, it would be easier to spot the planet with the naked eyes. A pair of binoculars, however, would be most useful. As the time passes by one would see the gap between the Moon and Venus becoming lesser. On June 18, the Moon rises about 3 hours after the Sun and therefore about five hours after the local sunrise the Moon will be well above the horizon to the eastern horizon. The new moon is on June 15 and on June 18 only about 15 percent of the visible disk of the Moon will be illuminated by the sunlight. It's phase would be 0.151 and thus it will appear crescent. It would be a magnificent sight closer to the sunset with Venus shining brilliantly above the crescent Moon.

Venus displays phases like the Moon. On the day of the event phase of Venus is 0.44. Though we know that some people can see phases of Venus with the naked eyes but most would need at least a small telescope to make out Venus' half phase.
It would take the Moon almost a minute to cover Venus completely. Angular size of Venus will be 26.41 arc seconds. However since only half of Venus is what we can see the event would be over in less then a minute. Normally it is not very easy to spot an object reappearing from behind the Moon, however, in this case with Venus being very bright it would not be too difficult, except that the reappearance phase of the event takes place too close to the horizon.

Occultation When one celestial body hides another one behind it, astronomers call the event occultation. By this definition, therefore, the solar eclipse is an occultation of the Sun by the Moon. Earthshine Ashen light Public Viewing at Oman, Jordan and UAE Vigyan Prasar and Nehru Planetarium Delhi

Some past events Occultation of Venus or other planets by the Moon are not very rare event though. The Moon does occults planets every now and then. On April 14, 2007, the Moon occulted Mars. On November 10, 2004, India witnessed occultation of Venus by the Moon in the pre dawn hours. That morning Venus disappeared at the brighter limb of the Moon. On May 29, 2003 India witnessed a day time occultation of Venus by the Moon, that is the disappearing and reappearing act took place when the Sun was above the horizon. The best event that was widely observed from
Indian was double occultation of Jupiter and Venus. It took place on April 23,
1998. The event took place around 1:30 p.m. local time. Many had claimed that
they could see Jupiter with their naked eyes, close to the brighter limb of
the Moon. |
