Wandering through the realms of the cosmos, pondering its huge vastness

Moon, Mars and Leo – Feb. 8, 2012

Mars in the eastern sky at 9:51 pm | Quezon City, Philippines

We were sitting on one of those weird benches surrounding the trees in the open-air space of UP-Ayala Technohub after having a rewarding dinner when I noticed a red-orange star in the eastern sky infront of us. My brain told me that, based on its brightness and location it had to be Mars.  It was hardly recognizable at first because the waxing gibbous moon was shining close to it. Moreover, we were situated in a very light-polluted area that my eyes were struggling to see those faint celestial objects near the horizon.

The red planet is back in the eastern sky at nightfall on these evenings. It is now in fact, one of the brightest “stars” (around -0.9 mag) in the night sky. It is growing even brighter and more prominent, especially towards the end of the month as it comes close to opposition to the Sun and its nearest pass to Earth.

Moon, Leo and Mars

Mars started to retrograde (move westward) toward the star Regulus in the constellation Leo last January 24. That happens whenever Earth is about to pass between the sun and Mars, which will happen on March 3, 2012. Mars has been brightening ever since retrograde motion began.

By the end of February, Mars will rise only 20 minutes after the Sun sets, so it will be easily seen by the time the sky darkens and will shine all-night long. By then Mars will have brightened to magnitude -1.2, nearly as bright as Sirius.

    Neat photos and observations! This years’ apparation of Mars has exceeded my expectations, which were a bit low because it’s not coming as close as it does during other oppositions. But it’s really been quite bright and prominent and enjoyable to see, and I’ve even glimpsed a few fuzzy surface details with my large reflector. Thanks for keeping us posted!
