    Venus and Jupiter conjoin

    By / July 1, 2015

    Conjoin? Well, not exactly. But I don’t recall ever seeing the planets closer together in the sky than they were the night of June 30, 2015. They were both near the center of my FOV in my favorite macro lens: Truth be told, I’d forgotten all about this conjunction of Venus and Jupiter until my… Read more

  • September equinox today, 10:29 p.m. EDT

    By / September 22, 2014

    Today, at 10:29 p.m. Eastern “daylight” time, Earth’s equatorial plane intersects the center of the Sun’s disk. Sunrise and sunset occur due east and due west, respectively, from all points on Earth’s surface. Equinox, man! Days and nights will continue to get shorter in the northern hemisphere, as they’ve been doing since the June solstice,… Read more

    Observe the moon this Saturday

    By / October 10, 2013

    International Observe the Moon Night is this Saturday, October 12. Head on out and look at the moon, just a day past first quarter and well situated for evening viewing. Get out there and get to know our nearest celestial neighbor, our partner and protector in space. Without the moon, why, where would we be?

    Closest perigee for the moon this year

    By / June 21, 2013

    Isn’t that a whole lot easier to say than “Supermoon”? But seriously, if you want to know what’s happening with this Sunday morning’s full moon, the best article I’ve seen in a while is over at Sky and Telescope’s website. The moon will appear about 7% larger than the average full moon, because it’s going… Read more

  • June solstice 2013

    By / June 20, 2013

    Tonight at 1:04 a.m. EDT, 10:04 p.m. PDT, the earth’s orbit will carry it to that point in space where the sun’s apparent path will once again stand still momentarily before it reverses course and begins to head back south. What? How can the sun stand still? Well, it won’t, really, but the origin of… Read more

    Dark(er) skies DIY

    By / February 14, 2013

    The problem: 6 peeling, light-polluting fixtures grace the exterior of the secretary of the Palm Beach County chapter of the International Dark-Sky Association, a nonprofit organization dedicated to the reduction of light pollution and skyglow. The solution: a trip to the local Lowe’s home center and a little “sweat equity” as they say on those… Read more

    October 2012 full moon

    By / October 29, 2012

    The Hunter’s moon rises nearly or completely full over three successive nights at nearly the same time each night. On Eastern Daylight Time this year, the nights of the 27th, 28th, and 29th, at 5:21, 5:57, and 6:35, respectively. Full moon is today at 3:50 p.m. EDT, but this shot was taken last night right… Read more

    September 2012 full moon: the birthday edition!

    By / September 29, 2012

    The 2012 harvest moon occurs tonight at 11:19 p.m. EDT. Only 395,493 km from Earth tonight. Libration, as you can see, is quite southern (see how far the bright crater Tycho is from the bottom edge?), and a bit of the eastern limb is more visible as well (if you know your selenography, you can… Read more

  • Happy equinox!

    By / September 22, 2012

    Late this morning, Earth’s orbit around the sun brought it to the equinoctial point. Today the sun rises due east and sets due west. But despite the etymological indication of “equal night,” day length and night length are only approximately equal today. (For more on this, see my post from 2009.)¬†How closely equal they are… Read more

    Full moon in August

    By / August 30, 2012

    The second full moon in August (well, about 12 hours before full). I found my digiscope camera! Despite what the Clear Sky Clock for Boca Raton says, this evening had nothing but high clouds and haze overhead, so while the naked eye views through the eyepiece were steady and beautiful, the camera view was a… Read more
