An exceptionally bright and long-lasting fireball meteor was recorded early Sunday morning by the NASA All-Sky Fireball Network camera situated on the campus of Hiram College. The event took place at 5:09 AM EDT, April 23, the meteor streaking from south to north as it burned up entering Earth’s atmosphere. Several other fireball meteors were also recorded during during the night but this was the brightest of the bunch. A fireball is a meteor that glows brighter than the planet Venus. NASA uses data collected from Hiram’s camera along with that from other systems in the network to learn about micrometeorites and their threat to spacecraft. Fireball Network images and data are available to astronomers and to the general public alike, and are updated daily.  Click here to visit the All-Sky Fireball Network website.

No December open night

Well we give up! The skies and the calendar just are not coming into alignment for a December Open Night! Clouds and inclement weather (of various temperatures) are making stargazing impossible and have been plaguing us quite often this season. And there’s no way we would schedule a public event for Christmas Eve!

So we’ll say thanks for your interest and hope more clear skies come our way next year.

Normally at this point we bundle up the telescope for the winter and schedule nothing until March. If, however, the weather presents us with sufficient notice of good observing chances we may just present a “pop-up” Open Night before spring. We would love to show off the Orion Nebula through the old scope! Watch our Twitter feed and/or check back here after the holidays for any surprises.

At any rate, we hope you will have a safe and warm winter and a wonderful new year. For those who observe it, happy Christmas to you!

And for everyone, here is a beautiful image of the Christmas Tree star cluster, provided by the European Southern Observatory (ESO) to help make the season bright. Enjoy!

Two-panel Moon

Two-Panel Moon: This photograph of the Moon, our latest experiment using the vintage Cooley Telescope in astrophotography, shows the Moon about two days from Full. Two individual shots were made using a Canon DSLR in place of the telescope’s eyepiece, projecting the lunar image directly upon the camera’s sensor. Exposure: ISO 400, 1/320 second. Adobe Photoshop was used to “photomerge” the individual panels or frames and edit the resulting image. [Click image to enlarge.]

We hosted a small group of 16 visitors during the July 16 Open Night but enjoyed the event very much; a group of that size is in the not-too-large and not-too-small range that affords easy conversation and sharing of the observatory experience. I the summertime we usually feature Earth’s Moon. Between summer’s late sunsets, and Daylight Saving Time extending twilight by an hour, the Moon reliably shows up even before the sky is dark! Saturday’s experience was no exception.

We viewed the Moon through the Cooley Telescope’s remarkable optics and were rewarded with exciting detail. Moving along as the sky darkened, we turned our attention to Saturn: the planet’s subtle color and distinctive ring system showed good detail, very good at times. We briefly viewed Mars but the Red Planet is rapidly parting company with Earth and has grown small in the telescope’s eyepiece.

Yes, the “star” of the night was Luna and, once the last visitors departed, we made a few images of our nearest neighbor in space to help illustrate why we love sharing the view!

Sunspot AR2529

Changing a word from an old song lyric by The Police, there’s a big black spot on the Sun today. Sunspot AR2529 is the dominant feature on our otherwise quiet star. Visible to the unaided eye through solar-safe filters, the sunspot is several Earth-diameters across and roughly “heart” shaped! This image was recorded Wednesday, April 13, at 2:19 PM. The bright orange color resulted from use of a solar filter covering the camera lens.

Here is what SpaceWeather.com says about the sunspot: “Since it appeared less than a week ago, AR2529 has been mostly, but not completely, quiet. On April 10th it hurled a minor CME into space. That CME, along with another that occurred a few hours later, could deliver a glancing blow to Earth’s magnetic field on April 13th.” A CME is a Coronal Mass Ejection wherein the Sun flings plasma from its atmosphere out and into space. CMEs reaching Earth can cause auroras.

Train of Sunspots, November 4, 2015

An impressive train of sunspots has been making its way across the face of our nearest star this week. In the photo above: Designated AR2447 (small group to the left), AR2443 (bigger and darker, near center), and AR2445 (far right), the “Active Regions” have the potential of unleashing flares. In fact, AR2445 was the source of a flare that caused this week’s “northern lights” sighted across northern latitude locations around the world. Now rotating over the Sun’s limb, AR2445 won’t be aimed at Earth for a while — if ever again — but AR2443 has potential for high-energy flares.

Latest solar image

The Sun – October 26, 2015

 

Preparing for this week’s expected heavy rains and wind, I went to the roof of the observatory to clean out the rain gutters and check the downspouts. Chores done and with the dome open, I made another experiment at solar imaging through the big vintage Cooley Telescope. I found I could focus on the Sun (through a safe solar filter) and, with a Canon DSLR camera at the telescope’s prime focus, recorded a few one-shot images at ISO 400 and 1/500 second. The telescope is a 9-inch refractor with a focal length of 3,327mm. The results appear better than last time but show the apparent effect of atmospheric turbulence: that’s my story and I’m sticking with it! A few sunspots were visible and details of Sol’s roiling atmosphere show up. The photographic technique is the simplest we can use; more sophisticated processes are employed these days to achieve best results. Still, proof of concept is a good thing and getting the image focused is a critical step. I think next time we may try a dimmer subject.
