St Charles County Parks Events

In addition to the "Friday Night Open Houses", which are free and open to the public every clear Friday evening at Broemmelsiek Park, we have selectively scheduled some special dates this year with the St Charles County Parks department.   These are our "Special Events", and most are related to special astronomical events that we choose to support.  Note that meteor showers can be very negatively affected by a bright moon, so we selectively support them based on visibility.

All Public events feature several telescopes and operators who provide views thru their scopes free of charge.  Both members and non-members bring scopes.  Anyone who needs help with their own scopes are encouraged to bring them, however please have them available for us to help you with them before sundown.  If your scope is working fine, but you'd like help to find some objects, please just ask one of our members (most of which will have a name tag).  We are glad to help you find things with your scope, please ask!

General rules at star parties apply to help all of us retain our night vision.  Please avoid bringing flashlights (unless they are red or covered by red plastic, and kept pointed "downward") or any other lighted devices.  Try to avoid shining car headlights at the telescope field as you park or leave, else please minimize it as much as possible while remaining safe (use your parking lights).   
Again, we are at Broemmelsiek Park every Friday night if the weather allows. 

Here are the "Special Events" events planned for 2015

Planned 2015 Events:

PERSEID METEOR SHOWER  -    Wednesday Aug 12 evening thru Thursday Aug 13 morning @ Broemmelsiek Park
The Astronomical Society of Eastern Missouri (ASEM) and St. Charles County Parks will be observing the Perseid meteor shower on the evening of Wednesday August 12 thru the morning of August 13 (weather-permitting). No formal presentation.  Just a relaxing evening under the stars.  This meteor shower is rated as one of the best, and the 2015 event will be near the New Moon, allowing more meteors to be seen.  While counts of 60 per hour are rated for this shower, that number may be more like what one person may see all night long, if paying close attention, in the partially-dark skies of Broemmelsiek.  Still, much darker and clearer horizons than from most backyards, and there will be plenty of other people to point out the ones that you missed!  Ooohs and Aahhs are welcome noises that remind us to keep looking up!

Dress warm, in layers.  Bring fluids and bug spray.  Electrical outlets are handy for fans if it is hot or heating blankets if cold (extension cords and sharing may be necessary).  Reclining chairs and blankets are very popular at this event.  Some scopes may be present, and I'd recommend you bring binoculars if you have them, as the Milky Way will be prominent and binos and lounge chairs are delightful together.  Our crowds for this event typically thin out greatly by midnight.  Please be aware that sunset does not occur until 8:02PM CDT.  It will not be dark enough to see the very brightest meteors until after 9PM, and it should be finally dark enough to truly BEGIN good viewing sometime between 9:30 and 10:00PM. Peak is forecasted for 2-3AM.

Per the American Meteor Society:
The Perseids are the most popular meteor shower as they peak on warm August nights as seen from the northern hemisphere. The Perseids are active from July 13 to August 26. They reach a strong maximum on August 12 or 13, depending on the year. Normal rates seen from rural locations range from 50-75 shower members per hour at maximum.The Persesids are particles released from comet 109P/Swift-Tuttle during its numerous returns to the inner solar system. They are called Perseids since the radiant (the area of the sky where the meteors seem to originate) is located near the prominent constellation of Perseus the hero when at maximum activity.

This shower is actually pretty good for a few days before and after Aug 12-13, so while the posted date above is official, meteor fans will be looking up on the days before or after the peak date depending on the weather!

TOTAL LUNAR ECLIPSE - Sunday September 27   @Broemmelsiek Park
The Astronomical Society of Eastern Missouri (ASEM) and St. Charles County Parks will be observing a total lunar eclipse (weather-permitting) on Sunday, Sept. 27, 2015 at Broemmelsiek Park and the public is invited to attend. Weather permitting, members of the prominent astronomy club will be on site of the Astronomy Viewing Area in the park, located at 1615 Schwede Road, Wentzville, MO  63385, from 7 p.m. to after 10 p.m. Maximum viewing of the Total Lunar Eclipse is expected to begin at 9:47 p.m. The total lunar eclipse will be visible across the United States and can be viewed with the naked eye.  

A total lunar eclipse occur when Earth's shadow blocks the sun’s light, which otherwise reflects off the moon. During the event, the Moon passes directly behind the Earth into its umbra (shadow). This can occur only when the Sun, Earth, and Moon are aligned (in "syzygy") exactly, or very closely so, with the Earth in the middle. Hence, a lunar eclipse can only occur the night of a full moon.

This September full moon is also called a Blood Moon because it presents the fourth and final eclipse of a lunar tetrad: four straight total eclipses of the moon, spaced at six lunar months (full moons) apart. The Blood Moon can be a spectacular event in the sky as the moon turns red during the total lunar eclipse cycle.
