* Prof. Leslie Hebb’s Cazenovia College Science Cafe lecture, “Distant Worlds: What We Know About Extra-Solar Planets And Their Potential For Habitability” was a great success this past Wednesday and we look forward to announcing and co-sponsoring future astro-related events.

* With one day to go and the potential for clear skies, interested parties are encouraged to read up on how to observe – and record – the lunar occultation of Aldebaran on the night of March 4th.

* And, finally, the March article is the perfect time to introduce new observers to Messier Marathons prior to any attempts of the same at month’s end.

Turning our attention to the North, and in anticipation of a larger discussion about circumpolar constellations, we introduce Ursa Major – a great, easy-to-find constellation with a small fortune in Messier Objects.

CNYO Observing Log: Green Lakes State Park, 25 July & 15 August 2014

* Session 1 – 25 July 2014

Exactly 364 days after our last outing past the now-defunct Fayetteville Friendly’s, Bob Piekiel and I hosted another well-attended session in the large open (frisbee) field of Green Lakes State Park on July 25th. This Friday evening saw reasonably warm and dewy conditions and no small amount of bug spray. The generally young crowd (2/3’s in the mid-teen or younger) was treated to Bob and mine’s usual post-dusk schtick, early sights of Saturn and Vega, and then a small host of other celestial objects as the night grew darker (after many of the youngest were dragged away by schedule-conscious adults).

After setup, the race was on for one of us to find Saturn to make sure everyone had seen at least one planet before leaving. After a lucky run of star finding (Vega and Arcturus) to align his Celestron NexStar 11, Bob had a long planetary line behind him, leaving me to start the evening with my New Moon Telescopes 12.5″ Dob on Vega (giving my post-Saturn line a glimpse of increasing numbers of stars around Vega as it darkened). By the end of the Vega line, Saturn was obvious to all and Mars was just between widely-spaced branches, allowing us to fill in the planet views before 1/2 the attendees (and all the youngest observers) left just after 9:00 p.m.

The rest of the evening was the usual free-for-all. While the sky still wasn’t nearly dark enough for dedicated observing at 10:00 p.m., we were fortunate to have a remaining group with both great interest in astronomical phenomena and vivid imaginations to fill in the perceptual gaps left by distant Fayetteville lights and our own early event timing. The discussions around the scope were as well received as the objects themselves.

As you might expect, having a session almost exactly 1 year apart means that the “pick hits” of last year were very similar to the “pick hits” of this year. The only real difference was the swapping of one swiftly-moving planet (Venus) with another (Mars). Saturn, in that one year block, has slid only slightly from Virgo last year to Libra this year. As for my usual policy of presenting at least one from the list of standard types of objects at each session, my observing and lecture list was as follows:

* (Hopefully) One PlanetSaturn
* One StarVega in Lyra was the obvious choice, giving all an early view of how bright stars shimmer strongly upon magnification (and allowing us to show how the shape of the spiders holding up our secondary mirrors affects our views). At Bob’s request, we also threw in Herschel’s Garnet Star in Cepheus as an example of very strongly-colored stars in the night sky (after showing Albireo to demonstrate the same).
* One BinaryAlbireo in Cygnus. I also included epsilon Lyrae in Lyra as it was close to Vega. Alcor and Mizar in Ursa Major are also excellent for testing visual acuity among attendees (and the magnified view gives still more to say about double stars in our neighborhood).
* One Open ClusterThe Double Cluster (Caldwell 14) in Perseus
* One Globular ClusterM13 in Hercules
* One NebulaM57, The Ring Nebula in a href=”https://en.wikipedia.org/wiki/Lyra”>Lyra. The use of an inflating balloon to demonstrate how you can see through the middle of a well-inflated balloon but can’t see well through the edges is as clear an explanation of what the Ring Nebula is from our vantage point as any other I can think of.
* One GalaxyM31, The Andromeda Galaxy in Andromeda. Despite the closeness to the horizon, M32 and M110 were also visible to observers at low magnification.
* Anything Else? – we were treated to several dozen obvious satellites and at least one bright meteor tail before packing up.

* Session 2 – 15 August 2014

The week of August 11 – 17 will be remembered as an almost useless one for CNY amateur astronomy. The Perseids were not only washed out by the timing of the Full Moon, but also by the constant overcast conditions (mixed with a few interesting lightning storms). Planned sessions at Baltimore Woods, Beaver Lake Nature Center (rescheduled for August 21st!), and North Sportsman’s Club were all scrubbed.

Given the lousy conditions all week for nighttime observing, I was a bit hesitant to drive out to Bob Piekiel’s August 15th session at Green Lakes State Park (even with one scope, it’s a lot of gear to drag around for a session where it won’t be used). That said, the Clear Sky Clock indicated a potential opening in the 9-ish to 11-ish range and the s’mores weren’t going to eat themselves. The crowd of around 25 (all crowded around a fire pit that smelled of charred marshmallow) were ready to observe and full of questions and fun discussion, so the early views of Saturn, Vega, and Arcturus were enough to keep us all occupied.

Around 9:20 p.m., a small miracle occurred as a massive clearing of the sky swept South/SouthEast, taking with it all of the present clouds in a slow, straight band that eventually gave us views of the entire sky before closing back again around 10:30 p.m. The clear, steady 70 minutes were more than enough to allow us to re-scan last month’s observing list (all little changed since last month!).

Old and new light – the end of the fire pit and inspecting flashlights.

With everyone departing soon after, we were left to take in a bit of the remaining fire in the pit (and our observing attire left to take in that burning wood smell) before giving the grounds one last scan with a bright flashlight before departing. A lousy evening turned into a fantastic (and slightly shortened) night for a Public Viewing Session. Kudos as always to Attilla Danko for his ever prescient Clear Sky Clock!

CNYO Observing Log: Baltimore Woods, 22 March 2014 (And An Erigone Summary)

Greetings fellow astrophiles!

The often-announced (on this site, anyway) Regulus occultation by asteroid (163) Erigone on the morning of March 20th was a near-wash (no rain, but plenty of cloud cover), with only a few messages being passed around at midnight to see if anyone was even going to try for 2:00 a.m. That said, the International Occultation Timing Association (IOTA) got lots of good press and, with luck, a similarly notable occultation will occur to catch other eyes and instigate the IOTA to prep another big public recording effort. Those who want to relive the non-event can watch the Slooh Community Observatory coverage in the youtube video below.

Then, two days later, Bob Piekiel with his Meade C11 and I with my New Moon Telescope 12.5″ Dob treated two couples at Baltimore Woods to the kind of crystal clear and steady skies you read out but usually never have the good fortune to be out for. With the late March and early April temperatures beginning to melt the high hills of ice and snow around all the big parking lots in the area, the Baltimore Woods setup was a bit solid, a bit slushy, and quite dirty. Our four-person audience arrived early in time to watch the clear skies darken and Jupiter, Sirius, and Betelgeuse first appear in the South/Southwest sky. For the next 90 minutes or so, the observing list included Jupiter (several times at several magnifications, both early in the evening and after the skies had sufficiently darkened to bring out more detail), the Pleiades (M45), the Beehive Cluster (M44), the Orion Nebula (M42), Alcor and Mizar in the handle of the Big Dipper, the Andromeda Galaxy (M31) and its prominent satellites (M32 and M110) very low on the horizon (very likely our last catches of our sister galaxy for several months to come), and even M82 to say that we had, at least, seen the location of the recent supernova (if not a last few photons from it).

In an attempt to help someone remember as many constellations as possible at the Liverpool Public Library lecture a few weeks prior, I retold one of the more memorable tales of the winter star groupings of Orion the Hunter, Taurus the Bull, Canis Major (the big dog), Canis Minor (the little dog), and the Pleiades that I picked up from the excellent Dover book Star Lore: Myths, Legends, and Facts by William Tyler Olcott (which you can even read and download for free in an earlier form at archive.org).

Long story short, the Pleiades (also known as the Seven Sisters or the Seven Virgins) were the target of Orion’s rather significant attention, so much so that in his last run to them, the ever-invasive Zeus placed an equally significant bull in Orion’s path, leaving Orion and his two dogs (Canis Major and Canis Minor) stuck in their tracks. As is apparent from the images below, these four constellations (and one star cluster/Messier Object) are all tightly spaced in the Winter Sky. Better still, the end of Winter even finds these constellations standing on the horizon (instead of upside down in morning Autumn skies), making the picture all the more easily seen. As Orion is second only to the Big Dipper in terms of ease-of-seeing by practically everyone (raised in the tradition of Western Constellation arrangements, anyway), it’s the start constellation from which to find the other three. Canis Major is easily found by its shoulder star Sirius, the brightest start in our nighttime sky. Canis Minor is a leap from Sirius to Procyon, also a prominent star. Taurus the Bull is easily found by its head, the local star cluster known as the Hyades, and its orange-red eye, Aldebaran. The small sisters lie within the boundary of Taurus in a cluster that to the slightly near-sighted might just look like a fuzzy patch (but which, in binoculars, reveals numerous tightly-packed stars).

After packing up around 9:30 (about when the temperatures began to drop precipitously), I managed a single long-exposure image with my Canon T3i of the region above – quite possibly my last good look at the most famous Winter grouping until they appear again in the morning Autumn skies.
