View Full Version : 2012 Apparition of Mars

2011-Dec-29, 07:30 AM
Ruddy Mars is reentering our evening skies. Its early March opposition from the Sun will be the most distant of its current 15-17-year cycle, but at least it will be fairly high in the sky for northern hemisphere observers.

My detailed article previewing Mars’ 2012 apparition appears under the links for my related graphics at www.CurtRenz.com/mars

Photos and descriptions of Mars during its current apparition would be welcome additions to this thread.

I've created five new graphs and added them to my Mars webpage. They include data on Mars' angular diameter, percentage of disk illuminated, stellar magnitude, meridian transit time and apparent axial tilt. The latter indicates which pole is tipped toward us. www.CurtRenz.com/mars

Mars is growing brighter each night as it approaches its March 3rd opposition, now only twenty days away. Tonight from Chicagoland Mars will rise at 19:23 and about five minutes earlier each succeeding evening. Does anyone have photos or descriptions to share?

Thanks for the info!

Thanks for the info!

You’re welcome, Cross. Even though opposition is today, Mars will be its closest for this apparition on March 5 at a distance of 0.6737 AU and an angular diameter of 13.9 arcseconds. No, that's not as big as a Full Moon!

haha, yea, but in August we'll get the same email that has been around since 2003.

Here's how it looked from Boston earlier tonight:

Thank goodness for an east-facing window and a relative lack of clouds!
