  1. A quick heads-up that tomorrow there is a #LunarOccultation of #M45 #thePleiades visible from the UK. The #CrescentMoon shouldn't overpower the cluster too much. If you have binoculars it will look even better!

  2. An encounter with the occult(ation)

    Only a few minutes from occultation, Mars is seen just off the lower edge of the lunar limb in this full-disk image recorded at 9:09 PM EST. The event only occurs with planet Mars about once every 14 years. Photo by James Guilford.

    Clouds held off — pretty much — for us to observe the Moon occult* Mars, the reddish dot in the photo above. About once every 14 years or so, everything lines up just right and planet Mars is hidden by Earth’s Moon. Though Mars is about twice as big in diameter as our Moon, it was nearly 60 million miles farther away from Earth during the encounter — to the unaided eye, Mars looked like a tiny bright red star next to the Full Moon.

    As predicted by mathematics, Mars and Moon grew nearer and nearer each other until, at 9:12 PM Eastern Standard Time (EST), the Red Planet disappeared behind our brilliant orb.

    Passing clouds threatened to obscure the event but thanks to gaps between those clouds, there was enough clearing for observation. Shortly after Mars vanished, so did those inter-cloud gaps. With Moon now cloud-covered, we did not return to the 13℉ night to watch for Mars to emerge.

    *Occult: To cut off from view by interposing something. Commonly used as a noun to indicate something supernatural that is hidden from ordinary access.

  3. My attempts at photographing the #lunaroccultation. I missed the start as the Moon did not rise above the Diablo Range until about 10 minutes later. You can barely see Mars exiting above the Moon in the second picture.

  4. #LunarOccultationOfMars 06:01 UT 8th December reprocessed. This image was taken as Mars re-emerged from behind the #Moon. #ASI120MC camera, #Celestrron 3x Barlow #WilliamOptics 70mm #refractor Full technical details are on my Flickr page #Mars #Occultation #LunarOccultation

  5. #ICYMI: The #Moon moved in front of #Mars in an event known as a #LunarOccultation on December 7, 2022. This phenomenon, where the Moon passes in front of a #Planet, is fascinating to witness and can be captured through #Photography.
