Talk:April 2015 lunar eclipse

Old

So far this is just a stub-article, needs statistics added at least. The picture shows the moon on the northern edge of the umbral shadow, so it makes sense it'll be short. .... And this NASA chart shows the duration of totality lasts under 5 minutes. [1] Tom Ruen (talk) 22:09, 20 December 2010 (UTC)

solar eclipse 9 years before and after

Great article! But please add mention of associated solar eclipse 9 years before and after...-71.174.183.177 (talk) 12:37, 3 April 2015 (UTC)

Solar eclipse articles exist too, like from Solar Saros 139, Solar eclipse of March 29, 2006 and Solar eclipse of April 8, 2024. Do you have a reference for a 9 year relation between solar and lunar eclipses? Tom Ruen (talk) 22:58, 3 April 2015 (UTC)

It looks like this expresses the relation Saros_(astronomy)#Relationship_between_lunar_and_solar_saros_.28sar.29. "After a given lunar or solar eclipse, after 9 years and 5.5 days (a half saros) an eclipse will occur that is lunar instead of solar, or vice versa, with similar properties."

Very short duration?

I have heard that this total lunar eclipse (April 2015) is supposed to be of extremely short duration--less than twenty minutes. That would make it noteworthy.

It is possible that the eclipse was only a deep partial. See http://www.skyandtelescope.com/astronomy-news/observing-news/april-4th-lunar-eclipse-not-total-040320156/ — Preceding unsigned comment added by 65.218.200.126 (talk) 09:43, 6 April 2015 (UTC)

Left and right

The diagrams at the top of these pages say the moon “passes right to left” through the shadow. In Melbourne, Australia (southern hemisphere) I find these diagrams rather misleading or incorrect. Since the moon is in the northern half of the sky, and you face the north when looking at it, it rises from the right and sets to the left. So I tend to interpret the diagram to be showing the passage of the moon through the sky. However I now realize that the diagram is up-side-down if you are facing the north. East is on the left-hand side, and north is upwards. I’m not sure of the technical correctness, but perhaps these captions could say “the moon passes from west to east relative to the shadow”, or warn that it only works in the northern hemisphere or when facing south.

Good point. You'd really need two diagrams to show north or south up, but it would be better of the diagram was labeled, north up, east left, west, right, south bottom. Tom Ruen (talk) 23:15, 7 April 2015 (UTC)

Thanks for your new caption mentioning west and east; it is definitely an improvement. I suspect the same problem is repeated on many other pages, e.g. October 2014 lunar eclipse, September 2015 lunar eclipse. However some pages already have different wording, e.g. June 2058 lunar eclipse: “passes west to east (right to left)”. Vadmium (talk, contribs) 00:37, 8 April 2015 (UTC).
