I've decided to start doing this journal again, mainly because there are often interesting items that are meaningful only in the context of geohashing, and I don't want to keep boring my Twitter followers with esoteric jargon. For example, there's an amazing situation this weekend, which I think should be called a "Geohashing Syzygy", where three points are in a neat line. This one has a very high longitude fraction, so the results are interesting. Around the Greenwich meridian they make for hash points that are really far apart (in this case, about 120km I think):



At the same time, at 180 degrees of longitude the syzygy produces five points that could all be reached in three days, while travelling less than 50km. That is, assuming you can traverse that sort of terrain in straight lines, which seems doubtful:



The reason there are five points has to do with the 30W Time Zone Rule. If you're new to geohashing, you should read that page, as it's quite important.

That's all for today. This journal will probably be sparse and sporadic, but I feel better, knowing it's here.
