A table of viewing times is HERE. In Oklahoma the eclipse should begin to be noticeable at around 4.40pm.
Everyone and their dog has already predicted, interpreted and pontificated at length on astrological implications. I'm not about to add much to the astro-chorus.
Back in 2008 I had the cheek to announce on this blog my own half-formed (more likely half-baked) theory about eclipses. They are relatively quick phenomena, I wrote, as compared to a transit of one of the outer planets : Uranus, Neptune, Pluto, and even Saturn. When those planets, in transit, hit a sensitive point or planet in your natal chart you know it. They stay long enough to make waves in your life, you can recognise their presence; results are often profound. Faster moving personal planets touching a sensitive spot, are much less recognisable, if at all, in my experience. This is why I doubt that effects of an eclipse, Solar or Lunar, upon the individual are likely to be as dramatic as is sometimes supposed. Recognisable? Yes, maybe sometimes, but not life-changing.
As an old blog-buddy (R J Adams)once commented, "Or, it could just be one chunk of rock passing between another chunk of rock and a large fiery thing?" My response: Could be, RJ! But have you ever driven along a highway listening to the radio when the station fades because you passed through a tunnel or near a high hill - could be something akin to that, not exactly, just an analogy. Nobody knows, so it's as well to investigate and keep an eye on what happens, in case we might learn something.
My take on eclipses in general hasn't changed much over the past six years. An additional thought occurred today : it's very difficult to attribute stuff specifically to an eclipse unless there's nothing else at all going on in a natal (or mundane type) chart. There's never going to be a point at which "something else" in a chart could not also be seen as reflecting a change or event which could also be attributed to an eclipse. Would the same events or changes have happened had there been no eclipse ? Impossible to say.
