On the night of Saturday, October 28, a low-magnitude partial lunar eclipse will occur that will be visible from all of Spain. The eclipse occurs while the Moon is conjunct a very bright Jupiter.
On Saturday, October 28, at twilight, about half an hour after sunset, Jupiter and the full Moon are now visible at a few degrees of elevation above the horizon. As the stars rise in the sky, the southern edge of our satellite will enter the shadow area that the Earth projects in space.
The partial eclipse will begin at 9:35 p.m. (official time for the Peninsula and the Balearic Islands). The maximum will be reached at 22:14, with the Moon at 34 degrees of elevation above the horizon and with a magnitude of 0.12, that is, only 12% of the Moon’s diameter will be covered by the shadow. From that moment on, our satellite will gradually leave the shadow zone to recover its full luminosity at 10:53 p.m.eclipse end time.
The attached figure details the development of the eclipse in Madrid, in other places in Spain the situation is slightly different, for know the eclipse sequence In the different provincial capitals you can consult the website of the National Astronomical Observatory (IGN).
As we see, this eclipse will be a very subtle phenomenon, since the fraction of the Moon that will enter the shadow it is very small, but enough to be visible to the naked eye. In addition, the eclipse will be embellished by the proximity of Jupiter, which will be visible, very bright, about six degrees east (to the left) of the lunar disk.
