Lunar (Werner) X for 2010

[qcdougn]

Any one have the dates and times UT for the Lunar X to be visible.

Cheers,

Doug

[Doc]

As far as I know its viewable during a four hour period just before the Moon's first quarter phase.

Thanks for the info Doc...now to calculate when that might happen and be convenient to view at a reasonable hour...

Quite a lot of info here...

The Lunar Terminator Visualization Tool looks interesting the link in the PDF doesn't work but it can be found here...

This is probably the easiest install as you just unpack this zip file

Setup your location information and then you can use the software to predict future events...

IF I have understood the "event" and IF I have used LTVT correctly (and thats two BIG IF's inthe same sentence) then i get these results (my lat long removed)

The brilliant Lunar Calculator software will also produce predictions for the Lunar X

Lunar Calculator v2.3.

After inputting my longitude and latitude, I simply put in co-longitude 358.0 and asked it tell me similar illimunations. It'll also tell you if the Moon is visible and its altitude. The software is only £10 and I use it a fair bit. Payment can be a bit of a faff (£10 note posted to Canada!). As it's one-man-band paid for software it would probably be unfair to the author for me to post the results here.

What I will say is that the 2010 dates and times fit in with the results that Peter posted as produced by LTVT. The difference with LunarCal is that it tells you visibility info for your location as well.

Cheers Mike...

Glad I had used LTVT properly... lok like the forum software is removing the tab/whitespace "spacing" so the data looks a bit wierd...

Where there's a will there's a way...
