It is very important to understand what is being predicted and adapt the script to that prediction. One will have to estimate how long before is.įor myself there is no obvious advantage of one approach over the other as both require some judgement calls in the scripting. One might takeĪn image after as a fudge for imprecise time or estimate, but the real action will occur in the seconds before this Images before and after the C2 point listed by this prediction to capture all of the action.Ī program whose C2 prediction is for the last valley to pass predicts the end of the totality process. Thus for photography one would need to balance Will fully begin at the true C2 point where the last valley passes the edge. High peaks on the edge of the moon will likely have already begun forming beads. As a practical matter this will likely be in the middle of Same prediction made by Meeus, Espenak, et al. This program will predict the time that a Spherical moon will interact with a spherical sun. I chose to adopt xjubier's convention of only updating 20. (Eclipsewise) has not, as of this writing, Note that not all of the web based JavaScript calculators have adapted to this change. I plan to issue other updates when the July 2023 (for Oct 23) and January 2024 (for Apr 24) numbers are published. Since this value now requires close monitoring, the program will flag when the value is greater than 6 months old for any near term eclipse. With this change this program’s predictions exactly match my own event measurements for the April 2023 eclipse. In this version the values for Eclipses in 20 are based on measurements of ΔT by the Stopped growing which threw off calculations based on the historical record. Before 2019 this changed at a fairly constant rate however, in 2019 this value One of the parameters used by the predictions in this program is ΔT (aka TT-UT) which models irregularities in Earth’s rotation. To date event times from your current location without relying on an internet connection.
Integrates with Apple Maps (and Google Maps on iOS ®) as described in Maps below to test possible new sites. However, I have had to frequentlyĪt my "ideal" site (or the site was itself moving ). Present a Google Map that you can use to determine where to go. If your goal is to figure out where to go to see an eclipse then I recommend using the
#SOLAR ECLIPSE MAESTRO KESTREL MAC#
I am pleased to announce that CaptureEclipse is now available on the Mac App Store.
#SOLAR ECLIPSE MAESTRO KESTREL CODE#
This, in turn, lead to learning about the algorithms to make eclipse predictions and making that code available first as an iOS ® app and then Those reasons (and COVID boredom) led to work starting on the macOS ® CaptureEclipse.Īfter completing the scheduling engine I decided that I wanted the ability to generate event times. Traveling with an operational computer running Mojave is also a non-starter. Running on a VM in the field was not an option. M1 machines Apple announced in late 2020. Will not run on Catalina (or later versions) nor be compatible with the long battery life Why write another app that does eclipse prediction? This started with a macOS ® app I am writing to control my camera ThisĪllows the user to get the exact event times for the exact location even while bouncing around on the bow of a ship.

This app provides estimates of where and when the various events of an eclipse will occur without needing access
