International Observe the Moon Night - Occultation new
      #6059128 - 09/02/13 12:07 PM

Saturday, October 12 will be the 2013 International Observe the Moon Night. I’ve discovered that magnitude +3.1 Beta Capricorni will be occulted by the Moon that evening for much of North America.

For observers at Chicago’s Adler Planetarium I predict that immersion will occur at 20:15:16 CDT and emersion at 21:29:33 CDT. If you would like occultation predictions for your location, please reply to this post with a longitude, latitude, elevation and time zone.

Occultations of fairly bright stars do not occur too often for a particular location, but for this one to be presented to North Americans at a convenient time during the Saturday evening of an international event is phenomenal. In about a week I’ll provide related graphics and data on my occultations webpage: www.CurtRenz.com/occultations

OK, Curt.

How about 33.6N, 117.3W, 1330ft. PDT.

Thank you.

David, please understand that the rough precision of your coordinates will result in rough approximations of the timings. I'm afraid that immersion at your location will occur during the daytime and emersion just minutes after sunset. Sorry, but this occultation is best suited for observers not in the far west of North America.

17:13:46 PDT Immersion
18:26:43 PDT Emersion

Willie, you and your group will be at a fine location for the occultation. I'll see what I can do about keeping your sky clear.

This event is gathering steam. There should be a large group assembled at Chicago's Adler Planetarium.

Ok this could be a very interesting occultation. Typically a lone star winks out as the moon covers it over such is the speed of the moon and small apparent size of the star. This however is an incredibly tight double at a distance of 0.04". Hopeless of course for the amateur. But in immersion and Emerson rather than seeing the star wink out or back in - its a gradual dimming or brightening as the components are 3.1 and 4.9 mag.

So the wildcard here is wether or not we can see a dimming which is an indirect resolution of the double that would reveal its duplicity.

Curt - my thanks for your posting this. If my information is askew my apologies. Here's the link to my reference...

Looking at the Calsky.com alerter for Occultations of Stars and Planets for my location I noticed another Lunar occultation for this coming Friday, this one for 3.9 mag Rho Sag.

Friday, Oct 11

19h21.2m Moon Immersion of Rho1 Sgr, SAO 162512 (Close double star), 3.9mag, Position angle=83.6°, Altitude h=37.0°, Moon phase=50.7%, Sun elevation hsun=-11.7° (dark limb)

20h41.2m Moon Emersion of Rho1 Sgr, SAO 162512 (Close double star), 3.9mag, Position Angle=241.9°, Altitude h=31.8°, Moon phase=51.4%, Sun elevation hsun=-28.0° (bright limb)

Missed immersion of Rho1 Sag! Was fiddling with a iPhone time app for a few moments and when I looked back in the EP, the star was gone! Totally misjudged how much time I had left.

Going to try and catch emmersion around 8:41 PM CDT.

I hope the weather cooperates for tomorrow night!

I'm preparing to go to our public event tonight at the Science Center. We've got certificates printed from IOTMN web site and plan to use them as rewards for crater locating. This will include a planetarium show, and a SciFi movie on the outside wall of the building. People set up on their lawn chairs, watch the movie, eat pizza and wander over to the scopes in the adjacent field. Should be fun!

Thanks for the data, but it turned out to be overcast at those times. A few hours later the skies were clear and I was able to show off Luna to a few people. Beta Cap was clearly seen about a moon diameter away.

I also appreciated the heads up, and was able to show what might have been using Stellarium software.
