This Wednesday evening the sky will offer a rather rare spectacle to the inhabitants of the northern hemisphere. In addition to the fireworks that will begin to celebrate the national holiday in France, the full moon will be bigger and brighter than usual. The ideal opportunity for astronomy enthusiasts to observe our satellite in detail.
This phenomenon is commonly referred to as the “Super Thunder Moon”. The adjective “super”, referring to these unusual proportions. And “thunder” referring to the period in which it occurs. July is indeed the most stormy month in the northern hemisphere.

Up to 14% larger

This phenomenon is explained by the proximity of the Moon to the Earth. Indeed, the satellite does not turn in a circle around our planet, but in the shape of an ellipse. Thus, it is sometimes closer and sometimes further away. And when it is closer, it logically appears larger to us.

Conjugated at the time of the full moon, the difference is then easily observable. Scientists estimate that at most it will be 14% bigger than usual, and 30% brighter.

How to observe it?

With the episode of heat wave crossing the Oise, the sky should be clear enough to observe the Moon this night from July 13 to 14. This requires moving away from bright areas, such as built-up areas, and being ready. In France, the full moon will appear between 10:23 p.m. and 4:52 a.m.
The ideal is to bring a telescope to better distinguish the details. But a pair of binoculars will do just fine.
