8:59:50am You don't hear/feel THAT every day!! What sounded AND felt like demolition explosion, has been confirmed as a "Boom" relating to meteor. Was it just a sonic boom as it passed over head? This was heard & felt from Lorain to Ashtabula. Was it the sound as the meteor exploded? Image info: NWS Satellite observing "flash" (approx. over Bay Village) Information is still coming in...

Last night was a beautiful, clear night... temp in the low 50s. I've been wanting to try this for quite a while. Flew the drone above the street lights to shoot the stars. This is a composite. The sky is made from 125, 2 second shots = a little over 4 minutes. The foreground is a panorama of 2 images. Both pieces were processed in Lightroom and blended in Photoshop. Shot in RAW format, 2 seconds, ISO 3200, f 1.8, DJI Air3S, Freewell light pollution filter.

Star parties in 2026 are held at our observatory in Medina County’s Letha House Park West, 5910 Richman Rd., Spencer, OH 44275.

If the weather is clear, our observatory will be open to view the night sky through our 8, 10 and 12 inch telescopes. Members will also have their personal telescopes to share with the public and answer questions. Educational displays will be available in the building. Cancellations may be made in the case of severe thunderstorms.

If you have a pair of binoculars or a telescope, bring them along. If you need help with your telescope, arrive an hour before the event and we’ll be glad to help. For your comfort, dress for the weather, wear shoes that can handle dewy grass & note that the temperature may drop as the night comes on.

If you need to bring a flashlight, bring one that shines red light if possible or point the light beam at the ground just ahead of you, not towards the telescopes or peoples’ faces. Bright white light can ruin dark-adapted vision and our view of a beautiful night! Please park your vehicles so that the headlights face away from the telescopes lined up along the north side of the parking lot (on the right as you drive in). Be careful when walking around the star party area; avoid stumbling for your own safety and to prevent damage to telescopes! Bring a folding chair or recliner to add comfort to your star-gazing.

Monthly Lecture Series are held 7:30 - 9:00 pm the 2nd Monday of the month in Telfer Hall on the campus of Baldwin Wallace University 336 Front St., Berea, OH 44017.

If you haven't heard... there's a comet passing through. You can catch some pics for another week then it's gone for about 80,000 years. First clear night that I've been able to look for it was last night (10/17/2024). I took these at the Cleveland Metroparks Hinckley Reservation between 7:30 & 9:00 pm last night at the Buzzard Roost area. A couple wide-field shots at 28mm and a couple close-ups at 200mm & 600mm. I couldn't see it with my eyes or find it in binoculars but it showed up just fine in my camera. This comet has an "anti-tail". It looks like a headlight shining from the core. You can see it a bit on the last 2 close-ups. This secondary tail appears to protrude forward from the comet's nucleus in the opposite direction of the “normal” tail. An anti-tail is not a physically separate feature, but a perspective effect created when the comet's tail arcs back behind itself from our point of view.

We have a comet in the evening sky. The weather should be better by Thursday. Binoculars may help.

Scientists think they have determined the source of the huge asteroid that killed most of the dinosaurs. Here's the article:

--Bill Murmann

Planetary scientists revealed the origins of the colossal asteroid that impacted Earth 66 million years ago, a violent event that wiped out most dinosaurs.
