Darkness came in heaps and lingered for hours last night. Although Comet Q2 Lovejoy competes well with the glare of the city and isn’t hard to see from my driveway, I craved something closer to a classic 18th century, electricity-free sky. That meant putting another 25 miles between me and Duluth.
From the countryside it was easy to just find the Pleiades or Seven Sisters star cluster and jump from there to the comet. As you can see from the photo map, Lovejoy will be near the cluster the next few nights. There’s still no moon in the sky, so I encourage to go out now for a look if you haven’t already. Even if you’ve seen it once or two, the comet bears watching every clear night. Fluctuations in the solar wind continuously change the shape, length and appearance of the ion or gas tail that’s so outrageously beautiful right now.
To my eyes, Lovejoy looked a little brighter (magnitude +3.8) last night than a week ago when it was closest to Earth. Even in 50mm binoculars you can see the pale blue color of the head or coma. The spectacular tail rays depicted in deep photos are much harder to make out. I could just detect a couple of them faintly in a 15-inch telescope when I moved the bright coma out of the field of view and allowed my eyes to fully dark-adapt. Tapping the telescope to bounce the comet around helped to make them stand out better.
We’ve got about another week of dark, moonless skies ideal for comet watching. Perihelion or closest approach to the Sun occurs on January 30th, so Lovejoy’s brightness may remain constant during this time even as it moves farther from Earth.
While you’re at it, point your binoculars at the nearby Pleiades for a face-full of stars. They’re my favorite in binocular cluster because the group comes alive with far more stars than are visible with the naked eye.
I hope you were able to see the conjunction of Saturn and crescent moon earlier today. I wasn’t able to see it at the optimal time in a dark sky at the start of dawn, but we still got a glimpse here.
On Sunday I’ll include a brand new map for tracking Comet Lovejoy over the next two weeks as it continues its northward climb.
