**2017 Total Solar Eclipse - August 21, 2017**


**SAFETY FIRST ***       Here's directives from NASA:
https://eclipse2017.nasa.gov/safety
Great one-page safety handout below (The advice on the flyer has been endorsed by NASA, the American Academy of Ophthalmology, and the American Academy of Optometry.)   http://bit.ly/2m5Ps2F
Under no circumstances should you use un-approved filters (such as CDs. DVDs, smoked glass, exposed x-ray films, etc).  These were often used in the past, but do not filter out UV radiation.  Retinal burns feel like sandpaper on your eyes!  Don't go there.


ASEM is one of several Eastern Missouri clubs and organizations that are preparing for this great eclipse.  Literally millions of people will be flocking to the center line to see this eclipse.  A Task-Force has been formed for the local coordination of efforts to publicly share this eclipse. We need early attention by educators, science leaders, local government, and legislators to assure that this very special and unusual event is enjoyed by our entire state's population.

I also suggest Graham Cave St Park, right off of I-70 at US 161, although no "event" sponsored there (so get your glasses beforehand).


HOW OFTEN DOES THIS HAPPEN?   Well, one happens 'somewhere' around the world (often over the oceans) about twice per year, BUT averages just one in 375 years in any particular spot on earth. The last total solar eclipse visible from the Saint Louis area occurred in 1442 (there was a fairly rare ANNULAR solar eclipse in the Lou back in May 1994).  The swath of the moon's shadow is fairly narrow.

Here are previous North American Eclipses for the past 100 yrs:
1900-1950           1951-2000
As you can see, the swath of totality is narrow, and there have been precious few in the continental US in the last 50 yrs.  The last one being in the Pacific Northwest states in 1979. So, this is the first total solar eclipse in the continental USA in 38 years!  (see this cool video from ABC News from 1979) The good news is, after 2017 North America will get a second chance" in 2024.  Like 1979 though, it will be in cloudy Springtime weather:  2000-2050.

IT IS PRETTY RARE to have one in the USA, and most everyone I know will want to take the day off, so why not just give in and make it a holiday?  It will be 10x worse than the first day of deer season!    10-reasons-missouri-should-make-august-21-2017-a-state-holiday.aspx

HOW MANY PEOPLE WILL COME TO SEE THIS EVENT?:
The easy answer is, as many as you can possibly handle, and then some!

Twelve million people actually live "in" the path of totality running from Oregon to South Carolina.  However, an estimated 200 million people live within just a one-day drive.  If just 10 percent of these come to "center line", that will more than double any "center line city" population in the path for the day.  If YOUR town doubles in population for 24-48 hours, what are the ramifications for business, hospitals, police, etc.?  For a such an event in an affluent US society, the attendance percentage will likely be high.  Obviously, the closer to "center line" the more explosive the population gain for the day.  Doubling or tripling the population near center line is likely.  Cities on center line can either 'host' an organized event profitably, or be unprepared for an invasion that will tax their local services and people will suffer.  People will literally stop on the side of the freeway if they do not have access to an approved venue.  Support systems near center line (health, fire, ambulance, traffic police, food, sanitation, etc.) will be over-burdened greatly if communities near center line do not prepare in advance.

WHERE TO VIEW IN ST CHARLES COUNTY, MO and SURROUNDING AREA:

While St Louis will not be the site of "Greatest Eclipse", just a couple dozen miles South at nearby Center-line this area will enjoy totality to a FRACTION of a second of that at greatest eclipse. In addition, our area has GREAT facilities (international airport, many hotels, restaurants, wineries, other entertainment, and good roads along the eclipse path).  We expect many Missourians from North and South of totality to move into the path of totality in MO for this event.  Likewise for many people from Arkansas (I-55), Iowa (via US 61), Illinois (I-55), and others.  It-will-be-a-very-major-event.

I expect that the BIGGEST event in the 'extended' ST LOUIS metro area will be at PERRYVILLE MO.   They will host at their soccer parks, city park, and airport, over 200 acres in all.  We also expect nice as well as LARGE events (closer to Centerline) in St Clair MO, Herman MO, Union MO, Herculaneum MO, Festus MO, DeSoto MO, Washington MO (Facebook), Owensville MO (Facebook), Sullivan MO, Augusta MO, and others.  Many wineries are in the path, and despite their mostly late planning I would expect them to be very busy that day. Check out Wineries in St Charles County MO.

At this point in time, the following locations in St Charles County are being planned to share the eclipse with the public:
1)  Klondike Park, St Charles County -          Totality :  2min 14secs    Capacity (est. 1,000).   (reservations required - FULL - reservations closed).
2)  Broemmelsiek Park, St Charles County - Totality:   1min 35secs    Capacity (est. 1,000).  Reservations required, see link in paragraph 5 above
3)  Quail Ridge Park, St Charles County       Totality:   1 min 1 sec      Capacity (est. 1,000).  Reservations required, see link in paragraph 5 above
4)  Wentzville Parks, Peruque Valley Park    Totality:   1 min 15 secs  Capacity (TBD)
5)  Trail Heads (TH) on the KATY TRAIL        Totality:   varies               Capacity (varies)
  MO DNR / State Parks is considering an Eclipse Bike event -and- an Eclipse Float event.
6)  Weldon Springs Interpretive Center      Totality:   1min 35secs    Capacity (?)
(this is the DOE containment mound area - LOTS of parking, limited space on top of mound)

EYE SAFETY:
*ONLY* during totality may you look at the Sun directly without protection (note - it is then that you only see the silhouette of the moon, as well as the Sun's faint corona, but you aren't really looking at the Sun itself during Totality).  Before (partial) or after totality (again, partial eclipse) you must use protection.  "Eclipse Glasses" (about $1 each or less if bought in bulk, in advance) are commonly used.  Else, solar projection methods or even a "cheese grater" can be used to see the partial phase.


=======================================================================
FOR EDUCATORS:
It is very hard to predict the future!  Human behavior is only slightly easier.  Take it for fact that, if your school does not address this eclipse sufficiently, your attendance will suffer greatly.  Indeed, it will be hard to handle the 'blue-flu" with teachers, subs, and bus drivers too.  Insufficient staffing will occur from staff to teachers to operations.

I predict that any school that is WITHIN totality here in St Charles County will make efforts to sufficiently handle this eclipse AT their school site  (let's say, if at least 30 seconds of totality).  Those (many!) schools that are outside totality, and only experiencing a PARTIAL eclipse, who - "if" having school that day - need to plan to BUS interested and deserving STUDENTS to an appropriate site within Totality.  If not, just accept the low attendance rate for the day.  Here is a LEARNING opportunity in the sciences, an INSPIRING event that encourages STEM careers, and a very rare "lifetime" type of event that MANY of your students and teachers will not want to miss.  --> A "teachers day" is suggested. 

Use this zoom-able map to determine if your school is within totality, and if so, how long totality is for that location:  NASA link  (point at your location, double-click)

A partial solar eclipse is fairly common, and is not in ANY way near the fantastic and rare personal experience of a TOTAL solar eclipse.  Some in St Louis remember a partial (ANNULAR - or "Ring of Fire") solar eclipse here in 1994.  A very nice eclipse, but NOT even close to the beauty or rarity of a TOTAL solar eclipse. If your school would like to consult with us, please contact us (email to Outreach).  Consider a comparison:  (1) attending a game-winning WORLD SERIES game, or (2) standing outside the stadium at a game-winning World Series game.  The ticket is free.  Get into the path of totality!!

=======================================================================

Eastern Missouri is a FRACTION of a second from "maximum eclipse duration" on this event ANYWHERE.  Center Line running through most of Missouri achieves 2mins 40seconds of totality, which is all (in full seconds) that can be achieved at the Eclipse Maximum point on this total solar eclipse.  The real trade off is to find a location very near Center Line, but with facilities for parking, water, and "necessities".  Public facilities, including medical support, are recommended.  Both St Louis and Kansas City provide a great starting point, in case clouds develop that day and eclipse chasers need to be mobile. The ENTIRE eclipse can be seen in Totality from Interstate I-70 for nearly the whole state! So, in case of local clouds easy and quick access to "Plan B" can be achieved.  Typical local weather in mid August is very dry and either cloudless. or partly-cloudy.  Both STL and KC offer great airports, and great capacity for hotel rooms and food services.  Likewise, in the event of bad weather or just to fill in the weekend, there is plenty to do and see in these metro areas.  St Joseph MO has already rented out its' airport for that day (2min 38sec) and is prepared to handle 70,000 people!!

As it was mentioned in one local committee meeting.  People will come to the center line, whether your local officials do any planning for it or not. The population nearest the center line area will effectively DOUBLE, triple, or more on Eclipse day.  Without local planning, serious problems can result from lack of sanitation, water, and "other necessities".  Good planning on the part of our local communities near center line will minimize problems and while hopefully maximizing profit potential for the many small cities in the path. Visitors will need hotels, food, drink, "other entertainment", and yes - - port-a-potties!  Late-comers to the planning parties will be paying extra for these 'mobile houses of necessity' to be hauled in from several hundreds of miles away. 

Many schools will see attendance be significantly down this day.  Persons taking time off for this will probably be equivalent to those that take off for some major holidays (such as Labor Day or Memorial Day).  Economically, there will be great demand near center line for the service industry, and if schools are in-session that will deplete the ability of the fast-food industry and others to handle the large demand near center line. It would be a pity if such a great educational and inspirational event would not be shared with young minds by keeping them hidden in classrooms that day.  I expect that schools located WITHIN totality will take an hour or two off, while schools within an hour or two drive (or more!) of totality will be arranging bus-loads for those who would otherwise not be present that day.  Traffic will be very busy that day, so leave plenty of time - avoid being in traffic from 9am to 3pm if at all possible.

Again, people should strive to get as close as possible to the "Center Line", as Totality will be the longest along that center line.  On the inside of the far edges of the line totality may be just a few seconds.  Let's face it, in partly cloudy skies, an extra 30 seconds (closer to center line) could mean seeing totality, or not!  Outside the band of Totality, the eclipse will simply be a Partial Solar Eclipse.  Most of Missouri will get over 90% of the Sun eclipsed.  * ONLY in the Totality phase may you look safely at the Sun without need for eye protection.* (see reference for Eclipse Glasses at the top of this web page).  Partial eclipses are not so rare.

Parts of ST LOUIS CITY and COUNTY and St Charles County will experience the TOTAL ECLIPSE.  The Northern parts will unfortunately only experience a PARTIAL eclipse.  It will be WORTH THE TRIP to head SOUTH!  The closer to center line the better (so, up to 2mins 40 seconds vs. perhaps just a couple of seconds at the edge - remember that the Moon's shadow is Round - so the eclipse at the edges is very short).  In St Charles County you'd want to be south of both I-70 and/or I-64 !
