ASKC General Meeting Information

General meetings of the Astronomical Society of Kansas City, are free and open to the public. We meet the fourth Saturday of each month (except December and for the annual picnic), usually in Room 111 of Royall Hall, on the campus of the University of Missouri at Kansas City, located one block west of 52nd and Rockhill Road.
Meeting time starts at 6:30pm with a "Meet and Greet" for guests and new members. The General meeting begins at 7:00 pm and usually ends around 9:00 PM. Come early at 6:00 pm to catch our Astro 101 series. Astro 101 is a source of information about various aspects of astronomy for everyone, and whether you are a novice or an experienced observer.

Meetings consist of some short business notes, our featured speaker and social hour. Plan on arriving early and take advantage of meeting our members, asking questions, and finding out what we are all about!at we are all about!

7:00 -Terrestrial Effects of Nearby Supernovae in the Early Pleistocene

The Astronomical Society of Kansas City’s General Meeting on July 23, 2016, will feature Adrian Melott Professor of Cosmology, Astrophysics and Astrobiology at the University of Kansas, Lawrence. His presentation is titled “Terrestrial Effects of Nearby Supernovae in the Early Pleistocene.”

In the presentation, he will discuss recent results that have strongly confirmed that multiple supernovae happened at distances ~100 pc consisting of two main events: one at 1.7 to 3.2 million years ago, and the other at 6.5 to 8.7 million years ago. These events are said to be responsible for excavating the Local Bubble in the interstellar medium and depositing 60Fe on Earth and the Moon. Other events are indicated by effects in the local cosmic ray spectrum. Given this updated and
refined picture, we ask whether such supernovae are expected to have had substantial effects on the terrestrial atmosphere and biota. In a
first cut at the most probable cases, combining photon and cosmic ray
effects, we find that a supernova at 100 pc can have only a small
effect on terrestrial organisms from visible light and that chemical
changes such as ozone depletion are weak. However, tropospheric
ionization right down to the ground due to the penetration of ≥TeV cosmic rays will increase by nearly an order of magnitude for thousands of years and irradiation by muons on the ground and in the upper ocean will increase 20-fold, which will approximately triple the overall radiation load on terrestrial organisms. Such irradiation has been linked to possible changes in climate and increased cancer and mutation rates. This may be related to a minor mass extinction around the Pliocene-Pleistocene boundary and further research on the effects is needed.


Meetings of the Astronomical Society of Kansas City take place at
7:00 p.m. the fourth Saturday of the month except September and December. The September meeting is the annual "members only picnic" and the December meeting is our annual holiday party.



We've added an informal meet-and-greet from 6:30 p.m. to 7:00 p.m. Board members and club members will be available to answer questions, chat about news of the day and in general get to know faces in the light, rather than voices in the dark. Treats will be available for the meet-and-greet before meetings and after meetings. Also after general meetings and weather permitting, you are invited to the roof of Royall Hall to look through some of the instruments inhabiting the Warkoczewski Observatory.



No we aren’t running a marathon, not even a Messier one. You always hear about the need to record your astronomical observations, yet how often do you postpone, forget or just decide “the heck with it?” Then you realize, upon starting an observing program, “I already did that one … if I had only written it down …”

There are other good reasons to keep an observing record. We will explore them n the July Astro 101 session. Scott Kranz, our ownb ASKC’s observing guru has a great list about the kinds of questions you can ask yourself when trying to describe what you are seeing. We will discuss some of those ideas, look at some examples and maybe do an exercise or two to help you get going on your own observing records. Come and make a record with us.
