IOTA/IOTA-ES occultation update for
             (933) Susi / HIP  54998 event on 2010 Nov 29, 21:50 UT
                      Visible from S China, India, SW Asia

Summary
-------
On 2010 Nov 29 UT, the 22 km diameter asteroid (933) Susi will occult a 8.3 mag
star in the constellation Leo for observers along a path across S China, India,
SW Asia.

In the case of an occultation, the combined light of the asteroid and the star
will drop by 7.7 mag to 16.0 mag (the magnitude of the asteroid) for at most 0.9
seconds.

This update is based on UNSO/Flagstaff astrometry for the asteroid kindly
provided by Alice Monet, historical astrometry from the MPC files (via AstDys),
and the following catalogs for the star position: .

It is shining in the West!

No! This is not an election advertisement! It is an advertisement for the god of good fortune Sukra or the goddess of love Venus (If you believe in Gods!!!!). Either way you should be interested. Venus has been shining and shining for the past few months imploring you to look at her/him! You can not step out after sunset and NOT see it in the western sky. There is something more to Venus than just being bright these days. What’s that? Let’s find out.

Planet Venus has dared to let the sun go ahead and has venturing further and further away in the sky from the sun and finally it will stop for a well earned rest on August 20th, well that’s another story to tell about the phenomenon called eastern elongation. But Venus seems to be enjoying this independence from the sun right now. It glows brightest now!

After few days its all set to date Moon. Looks like an interesting event, Venus dating a crescent moon. Not even dating, trying to hide behind moon, away from the glaring lights and cameras of news channels. But even these probing eyes of reporters and sting operations would not stop it meeting Moon on 16th afternoon. This event in astronomy is called occultation. Remember, sun hiding behind the moon? You are right, during solar eclipse it does that, technically solar eclipse is an occultation. An occultation is an event that occurs when one object is hidden by another object that passes between it and the observer. Last time it happened with venus for India was on June 17 2007. This event is not rare one but it sure is an event to watch as bright Venus slips behind the moon.


Image taken by SPACE members just before Venus went behind moon in early hours of Nov. 10, 2004

Now why this event occurs? As we all know that Moon goes around the Earth and during it journey it comes in front of rest of the celestial bodies. Sun, planets, stars to name a few. As a result we have all sorts of occultations. As moon moves quite fast in the skies, it comes back to the same phase in about 29.5 days, it stands a good chance to occult the planets and stars. A planet being hidden by moon is not a common event as there are only few bright naked eye planets, even then it usually hides Venus behind at least once in a year.

Timings for Delhi
16 May, 2010
Disappearance                         15 50 38 IST
Reappearance                          17 18 31 IST

For timings in rest of the major cities in delhi, please visit SPACE occultation blog at http://occultationindia.blogspot.com

It is a daytime event. Last time its happened during night/eve but next two events are daytime and one has to wait till 2036 to see this event in night.

Next three events
June 30, 2011              Daytime event
Feb 26, 2014               Daytime event
Sep 16, 2036               NightTime event


How to see the event?
As the event is happening in the daytime, one can not see the venus going behind or coming from behind the moon but it will be site worth to watch once the sun has set and Moon-Venus pair shining in the western skies.

Event for Amateur Astronomers
Amateur Astronomers can try out photographing the event as well seeing the venus in broad daylight with help of data available for the venus and Moon, but its not going to be easy.

May 16th Venus occultation by Moon in daytime



The map shows the area over which the event can be seen.
Continuous thick white line indicates night-time region. Red line indicates twilight region. Dotted white line shows daylight region


On Sunday, May 16, 2010, the Moon will come directly between Venus and the Earth. The event would be visible from India during the day time.

Last time it happened for observers in india on June 18, 2007 and next will be in June 30, 2011

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. 

For India the event begins after about 3:30 p.m. Indian time and ends after 5 p.m. The start and end times of the event are given in the table below.  At the start of the event the Moon and Venus will be well above the horizon.  The Moon itself will be about 30 degrees east of the Sun. It will not be very difficult to spot the Moon if the sky is clear and blue. All one needs to do is to face west and look about 30 degrees above the sun.. Needless to say that one should not look at the sun directly.

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. But if you are using a binoculars or telescope be very sure not to point the instrument in the direction of the sun. It is quite likely that one may not be able to see the dark limb of the Moon.

On 2010 May 11 18:11 UT (23:43 IST), the 37 km diameter asteroid (7476) Ogilsbie will occult a 5.0 mag star in the constellation Virgo for observers along a path across Japan,China, India, Africa. In the case of an occultation, the combined light of the asteroid and the star will drop by 9.3 mag to 14.3 mag (the magnitude of the asteroid) for at most 2.7 seconds. This sure is a very good event to observe as comparitevly bright star (5.o mag) is going to be occulted and the central path is passing quite near to Banglore, tirupati and few
other cities in south. SPACE is going to observe and record the event. More updates will soon be put up.
