On mobile there's no info other than "please visit from a desktop/laptop computer", so for anyone else not near one:
> Finds when the sun aligns with your street for a perfect sunset view (like Manhattanhenge).
> * Enter an address to check for alignment with the sunset (or more specifically, alignment a little before sunset, the last moment the sun is at 50˚)
> * Shows street bearing and sun alignment information
> * Displays coordinates and next henge date (if there is one)
Thanks for the summary. Irksome/Curious that the page throws up such a blanket go-away screen when I am using an iPad, which from my perspective is basically the same as a small laptop (only in the browser ofc).
