Compute eclipse start, peak, and end times for observer at a selected location. Also compute maximum obscuration.
See how close we come to NASA posted times.
I'm near the Palatine Public Library in Illinois. Here's what NASA shows for my location. Times are UTC:
NASA reference for eclipse path and timing.
This US Navy site explains the difference between magnitude and obscuration for an eclipse.
Most of the math for this is taken from the following blog posting and source code.
NASA posted times have been converted from UTC to US/Central.
