Santa Cruz of Tenerife / The third and largest supermoon of this year will be seen this week and will be from home, due to the confinement that is carried out as a result of the coronavirus pandemic.
The Canary Islands Astrophysics Institute (IAC) has given some recommendations to observe it, in order not to miss the opportunity to enjoy this celestial show in all its splendor, and has encouraged the sharing of the result on social networks using #SuperlunaDesdeCasa.
The night of this Tuesday will be the best time to observe it, when the full moon will be rising over the eastern horizon, indicates the Instituto de Astrofísica de Canarias.
Throughout the night and until dawn you will be able to see her cross the sky, and a beautiful moment to “immortalize her” will be during the sunrise or sunset.
With the horizon clear, some atmospheric effects of refraction can be observed and there will be enough ambient light to be able to see the landscape as well.
An hour after sunset and up to an hour before sunrise, there will be darkness, although not so much because of the full moon, and from that moment you can also see the stars and photograph them. And, before dawn, the Moon will fade as it approaches the western horizon.
How to photograph it?
To photograph it with mobile phones, you should not use the predefined (automatic) modes, but adjust the exposure manually.
For example, for a conventional mobile in a brightly lit environment (from a city, for example), ISO 1600, 2-second exposure and maximum aperture (minimum f) will suffice.
If the program that comes on the mobile does not have the possibility to adjust the shot values, you can download any of the hundreds of free applications.
The same for editing the images: it will be enough to be able to adjust the exposure, the contrast and the color, to achieve a more realistic and attractive result.
Some high-end mobiles come with integrated zoom or another camera with a greater focal length, which can help to obtain more detail, but in exchange you will lose part of the landscape, and mini-lenses for mobiles are also sold, with quite acceptable results, ensures the IAC.
The term “supermoon”
The IAC recalls that the term “supermoon” was popularly coined just a few decades ago and does not have a scientific use, but rather refers to the perception of the diameter and brightness of the full moon from Earth with respect to the apogee, the maximum distance at which this satellite is from our planet.
The Moon rotates on Earth with a period of approximately 28 days, but its orbit is not circular, but rather an ellipse, and that is why the Earth-Moon distance is not always the same and Therefore, neither are the size and brightness that we perceive of your image.
By definition, a supermoon will occur if the full moon happens near the lunar perigee, so this year you will hear about up to four supermoons (in February, March, April, and May).
There are between three and five supermoons a year
In fact, this astronomical event is so common that, normally, there are usually between three and five supermoons per year.
During these phenomena, the apparent diameter of the Moon can increase up to 14% and its brightness up to 30%, and in the case of the next supermoon, its apparent size and brightness will increase 12% and 29% with respect to the apogee. , respectively.
This will be due to the fact that next Wednesday, April 8, at 2:36 UT, the satellite will pass 357,035 kilometers from Earth (peak with the maximum distance in 2020, 406,690 kilometers).
In the most favorable situation, a supermoon will have a diameter of 4 arc minutes greater than a full moon at peak; that is to say, the increase in angular diameter of the supermoon is only one fifteenth of the angular size of a little finger when viewed with the arm extended, making it “really very difficult to distinguish with the naked eye.” (April 7, 2020, EFE / PracticaEspañol)
