Supermoon Mania

LatestForecasts for Sunday and Monday evenings are currently for clear skies on PEI. This is good if you want to get out and see the “supermoon”.

Why both evenings?

It is because the Moon actually reaches perigee (it’s closest point to Earth) at  7:24AM AST on November 14. It also reaches it’s “peak full phase” at 1352 UTC or 9:52 AM AST on the fourteenth.

However, the moon will look plenty full and bright all night long on both November 13 and 14 – as it rises in the east around sunset, climbs highest up around midnight, and then sets in the west at or near sunrise.

In fact, by 8:29PM AST on the evening of the thirteenth, the Moon will be 100% percent of full and will remain so for approximately 26 hours.

As moonrise occurs on the thirteenth will be at 4:34PM and at 5:16PM on the fourteenth, we basically have two evenings to see the “supermoon”.

Good luck seeing the difference in size however as the 14% difference is negligible to the naked eye.
