I'm pickin' up good librations

[Demonperformer]

As part of my ongoing libration zone project, I have been constructing a spreadsheet to identify my best dates for bagging particular features.  Some of this data may be of interest/use to others - although, as all the data is topocentric using my location, it should be approached with appropriate caution.

I am therefore attaching an extract from the spreadsheet which applies to the next lunation, beginning at the end of the month.  It should all be fairly self-explanatory using the "Notes" worksheet.

If there appears to be sufficient interest (based on download figures) I will continue to upload one for each lunation.  If there is little interest, I won't waste forum webspace by uploading it, but will happily provide the info by PM to any interested member.

Thanks for looking

AMENDED VERSION:

I have made an amendment to my spreadsheet and have uploaded accordingly.  This version gives greater weight to the direction and timing of longitudinal librations (the previous one resulted in longitudinal librations in the wrong direction being given credit!)

Here is the spreadsheet for lunation 1132.

Before downloading, it may be worth checking out http://stargazerslounge.com/topic/217120-interactive-libration-spreadsheet/ where you can download a worksheet in which you can set your own precise location and so get similar, but more-specific-to-you, results.

Thanks.
