*Special Events* at St Charles County Parks

In addition to the "Friday Night Open Houses", which are free and open to the public each and 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 and their Zenithal Hourly Rate.

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!  It is a public park - you are welcome, please have fun and remember that we are volunteers.

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.

UT = Universal Time (which is 6 hours ahead of CST in St Louis, so subtract 6 hours from the above, or use the chart below)
The January Full Moon is also known as the "Wolf Moon", and a lunar eclipse is often portrayed in the media as a "Blood Moon".

The 50th Anniversary of the Apollo 11 Lunar Landing (Saturday July 20) - Sundown to midnight

A Saturday evening event is planned to commemorate the anniversary of the historic first steps on the moon. We expect this to be a "throwback" to 1969 themed star party.  Moonrise is around 10:54 pm and we will then proudly display the moon in many telescopes to commemorate the anniversary.  Jupiter and Saturn will likewise be viewed.    *ALL EVENTS ARE DEPENDENT ON THE WEATHER*

Party like it’s 1969 !!

The Perseid Meteor Shower (Aug 12/13)=Mon eve/Tues AM

—Not an "official" St Charles County Parks event.  Join us at Broemmelsiek Park.    Unfortunately, this year the moon is nearly full (Waxing Gibbous - 93% illuminated. Full moon is August 15).  Since the vast majority of meteors will be dim ones, only a fraction of Perseids will be seen under such bright moonlight.  We will be seeing a few meteors at our Friday Night Open House on Aug 9 as well.  *ALL EVENTS ARE DEPENDENT ON THE WEATHER*

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 Perseids 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.




November 11 - TRANSIT OF MERCURY across the face of the Sun

                (graphics below per ECLIPSEWISE )     ***NOTE:   THIS IS THE LAST TRANSIT VISIBLE TO THE USA UNTIL 2049****


*****SADLY, DUE TO SNOW AND HEAVY CLOUDS, IT IS NECESSARY TO CANCEL THIS EVENT.*********




Subtract 6 hours from the U.T. above to get CST for St Louis (so I = 6:35 AM,  II = 6:37 AM,  GT  = 9:19 AM,  III = 12:02 PM, and IV = 12:04 PM).  Sunrise is 6:41 AM in St Louis, so this event starts before sunrise.




Mercury is a lot smaller than Venus, and is much further away from Earth as well.  It will cast a TINY dot on the face of the Sun.  Cool to see, but will require a telescope (filtered or projected) at a decent magnification.  Below are my photos from an event many years ago.  It will slowly move across the face of the Sun in less than 6 hours.


1 - Whole sun image (projected, 4,25" telescope).  Large sunspot at 2 O'Clock, tiny dot is Mercury around 3 O'Clock.

 

2 - Close up below.  Edge of sun shown (8" SCT filtered).  Mercury is the dot at top left.  Sunspot is larger, below.

3 - Same image as above, inverted colors and annotated.
