Eclipse2024.org's 2023 Annular Eclipse Community Page for Ontario, California
Here, you'll find all the information we've been able to find for Ontario, as they prepare to host visitors to view the great annular eclipse of October 14, 2023!
Eclipse2024.org does not endorse or approve any viewing sites or events related to the 2023 eclipse.

*All times shown are calculated for the lat/long specified above, and are accurate to within a couple of seconds, due mainly to influences of the "edge effects" at the start and end of annularity. For a more detailed explanation of this, please see the "About Accuracy" section of this great 2017 eclipse page by Ernie Wright of NASA!
These calculations were performed using a value of ΔT=69.2s.
Please also note that these times have been converted from UTC; if you see times that say "UTC", "UT", or "GMT", those are NOT the local times for you in Ontario!
Finally, please see our page about calculating eclipse times to the tenth of a second.
The eclipse in Ontario will be partial (with magnitude 79%).
(Get your eclipse glasses here – you MUST have them to safely view the eclipse!)
First, we'd suggest you contact local Chambers of Commerce and/or Town/City Councils
for the locations you're interested in.
Next, check out eclipse viewing and event plans that have been sent to us by officials of Ontario!
