TRANSIT OF VENUS - JUNE 5, 2012

TODAY IS THE DAY!!! The ''last in your lifetime'' event, the Transit of Venus


Details on our star party for the Transit of Venus can be found on the MAS Transit of Venus webpage.

You can also look in on the festivities at the Onan Observatory via our live webcam HERE.

If you can't get to our event, you can still watch the transit online. Follow the link to the Live Webcast from the summit of Mauna Kea, Hawaii

-----------------------------------

Finally, if you find yourself completely unprepared and can't get to a computer or any place to view the transit, give the tried and true 'pinhole camera' a try...

The Pinhole Projection Method - (From ''Mr. Eclipse'' website.)
One safe way of enjoying the Sun during a partial eclipse--or anytime--is a ''pinhole camera,'' which allows you to view a projected image of the Sun. There are fancy pinhole cameras you can make out of cardboard boxes, but a perfectly adequate (and portable) version can be made out of two thin but stiff pieces of white cardboard (heavy paper or paper plates would work well too).

Punch a small clean pinhole in one piece of cardboard and let the sunlight fall through that hole onto the second piece of cardboard, which serves as a screen, held below it. An inverted image of the Sun is formed. To make the image larger, move the screen farther from the pinhole. To make the image brighter, move the screen closer to the pinhole. Do not make the pinhole wide or you will only have a shaft of sunlight rather than an image of the Sun.

Remember, this instrument is used with your back to the Sun. The sunlight passes over your shoulder, through the pinhole, and forms an image on the cardboard screen beneath it. Do not look through the pinhole at the Sun.

Remember, above all else, be careful when viewing the sun. Whenever viewing the sun, viewing safety is paramount.
NEVER attempt to observe the sun or Venus Transit with the naked eye.
NEVER use an unfiltered telescope or binoculars to view the sun.
NEVER use a damaged solar filter or damaged solar eyeglasses to view the sun.
NEVER look through an unfiltered camera to view the sun.
NEVER look through the ''pinhole'' of a ''Projection Box'' to view the sun. As noted above, project the image on to a second piece of paper with the sun at your back.
And an oldie but a goodie, NEVER look through a photo negative to view the sun.

Failure to use appropriate filtration may result in permanent eye damage or blindness!




Onan Observatory at Baylor Regional Park

10775 County Rd 33, Norwood Young America, MN



The Transit of Venus is among the rarest astronomical phenomena and won't happen again until the year 2117. So prepare now, and don't miss out on this extremely special event!

The transit or passage of a planet across the face of the Sun is a relatively rare occurrence. As seen from Earth, only transits of Mercury and Venus are possible. On average, there are 13 transits of Mercury each century. Transits of Venus occur in pairs, 8 years apart, with more than a century separating each pair.

The last Venus transit was in 2004 so the second event of the pair will occur on Tuesday, June 5 from the Western Hemisphere. The entire event will be widely visible from the western Pacific, eastern Asia and eastern Australia as shown in Figure 1 below.

Most of North and Central America, and northern South America will witness the beginning of the transit (on June 5) but the Sun will set before the event ends.



Additional information can be found on the NASA website , at Sun Earth Day and
the Transit of Venus web page.



Schedule of Events (Subject to change)

Tuesday June 5, 2012 - The observatory will open at 4:00 pm, The transit begins at 5:04 local time.

This is an all weather event, the observatory will be open even if it is cloudy. The transit will be broadcast live online from Hawaii and we are planning on showing live video from there.


 
At the Onan Observatory we will be having a Public Star Party featuring the Transit of Venus. The Observatory will open at 4:00 pm. From Baylor Park, the transit begins with “first contact” at 5:04 pm. 5:22 pm will mark “second contact”, when the entire disk of Venus enters the Sun. The Sun will set just before 9:00 with the transit just past the midpoint. The transit will continue until about 11:49 pm local time.


What to expect: The Transit of Venus is expected to be a popular event for the public to view at Onan Observatory, which we have never experienced in our history. Please plan ahead, the traffic and parking might be congested as we are expecting more than 500 visitors for this event. Please plan to arrive early as you may need to walk a distance to get to the observatory. From Baylor Park the transit will last for about 4 hours. This should give everyone an opportunity to view it as well as getting a picture or two. Again, try to get there early and be patient, as the lines could be long. I strongly recommend arriving before 6:00 pm to have the best chance to see the event.

Bringing your our scope? We expect dozens of MAS members and non-members will want to bring their own scopes. There is ample room near the observatory and throughout the park for you to do so. Be sure to have a proper solar filter securely attached to your scope. If you bring your scope, please do not leave it unattended or without a proper solar filter.

Viewing Safety: To observe the transit of Venus directly you must protect your eyes at all times with proper solar filters. The observatory has many telescopes with solar filters as well as scopes dedicated to solar viewing. We will also have several solar “projection” methods to view the Transit indirectly. Information on proper solar filters and projection methods can be found HERE.

What if it’s cloudy? We are still planning on having the observatory open even if it is cloudy. The transit will be broadcast online from Hawaii and we are planning on showing live video from there.

Location: If you haven’t been to Baylor Park or the Onan Observatory, we are located about 45 minutes southwest of Minneapolis, three miles north of Norwood-Young America, MN. Directions and map can be found HERE. To see live video from Onan, click here.

Handicap Parking: : There are a limited number of handicap parking spaces near the observatory. At the very least we will see that the driveway is clear for those who need it to be dropped off at the observatory door.

Questions? : If you have questions about the transit event, send us an email at Info@MnAstro.org

You can also post your questions on the MAS Discussion Forums MAS Discussion Forums or follow the latest discussions. Last minute info would also be posted on the MAS home page at www.mnastro.org
