A solar eclipse occurs today, 12/14/2020 and will be visible in part of Brazil. During December 14, 2020, a part of Brazil will be able to observe a beautiful astronomical phenomenon: the Solar Eclipse. People in the observation range of this eclipse will notice that the Sun will be partially “cut off” because, although this eclipse is considered a Total Solar Eclipse, what will be observed in Brazil is a partial solar eclipse.
Do not miss this beautiful opportunity to observe this phenomenon, since the next eclipse that will occur in Brazil, will only be on October 14, 2023.
Cloud forecast for the eclipse of 12/14/2020
The success of an astronomical observation from the surface of the Earth depends on the climatic conditions. A sky full of clouds, rain, or even clouds that do not cause rain, but that remain in great quantity at the time of observation, impede the appreciation of the stars or, at least, hinder a lot.
Unfortunately for the solar eclipse of 12/14/2020, the weather conditions are not the best. Most of the areas in Brazil where the partial solar eclipse will occur will have a lot of clouds.
The entire event of this solar eclipse occurs between 12 pm and 3 pm and in this period, with the large number of areas of instability over Brazil, at least we will have a lot of clouds.
This does not mean that no one will see anything from this solar eclipse. In many areas you will need patience because the sun will be fighting the clouds to make them appear. But in Rio Grande do Sul, where the highest percentage of the eclipsed solar disk occurs, the conditions for observation are moderate to good.
The following map will help to know the cloudiness in the period between 12 noon and 3 p.m., when the solar eclipse of 12/14/2020 occurs. It will take patience!

The table shows the percentage of the solar disk that will be covered (eclipsed) in each Brazilian capital. The values were approximate.

Live: live broadcast of the solar eclipse by Professor Marcos Calil
Let’s hope that, at the time of the eclipse transmission, between 12 am and 3 pm, the clouds will not hinder the appreciation of the event in the Greater São Paulo region.
Professor Marcos Calil prepared a super special montage to transmit the solar eclipse of 12/14/2020. Check here the assembly details
On December 14, 2020, starting at 12 hours and 40 minutes, Prof. Marcos Calil will perform a live Super Special to broadcast the Solar Eclipse live. This transmission has an alliance with Climatempo, Sabina Escola Parque do Conhecimento, Instituto Iprodesc, Planetário de Santo André and the Sky Observation Center.
Special telescopes for observing the sun
For the realization of Live, two telescopes will be used. The Coronado telescope, specific for observing the sun, will have a camera 1 to present the eclipse in the H-Alpha frequency. The 200mm Newtonian reflective telescope, using camera 2, will be equipped with Baader and Thousand sunscreens. In addition, two other open chambers will be used. Camera 3 will constantly head skyward, displaying the weather conditions. Camera 4 will support Prof. Marcos Calil didactic and fun to present the different ways of observing a solar eclipse, either directly or indirectly.
Don’t miss out on this Super Live Special. Register now, subscribe to the channel and activate the notification so as not to miss any astronomical phenomenon that can be observed in the sky of your city.

Global view of the solar eclipse of 12/14/2020
The solar eclipse that occurs on December 14, 2020 will be a Total Solar Eclipse only for people located in a narrow strip that extends over the South Pacific Ocean, passes through southern Chile and Argentina and advances through a portion of the Atlantic Ocean. South.
In part of Brazil what can be seen is a solar eclipse in its partial form. That said, let’s now know which regions of Brazil will observe the solar eclipse on December 14, 2020 and their approximate times.
Who will be able to observe and main observation times
According to the map shown in figure 2, Brazilians located below the green line will be able to see this eclipse as a Partial Solar Eclipse.

Figure 2 illustrates the Aspects that observers located in Brazil can contemplate this beautiful Solar Eclipse. We found that the further north in Brazil, the smaller the portion of the solar disk was eclipsed by the lunar disk. Therefore, observers located in the South Region of Brazil will see that the Sun “cut off” more sharply, compared to observers located in the Central-West Region of Brazil. Unfortunately, observers located in the North Region and in the North part of Northeast Brazil will not be able to observe this astronomical phenomenon.

Another interesting aspect to observe are the Schedule. It is worth mentioning that the times indicated in this figure follow the Brasilia time and they are approximate.
We realized that by different regions of Brazil Solar Eclipse has different times beginning, maximum and end of the eclipse.
It is also worth mentioning that it is necessary for the observer to have a sky without clouds or with little cloudiness to contemplate this phenomenon.
Very important: eye protection to see the eclipse
A Observing the solar eclipse requires great care.. It is important to note that direct observation of the Sun or the The use of non-specialized devices can cause irreversible damage to vision and even, in extreme cases, blindness.. Therefore, X-ray plates, photographic film, smoked glass, reflections in water basins and other artifacts should NOT be used to observe the sun.
What not to do when enjoying a solar eclipse
And how to observe?
There are two very safe ways to observe a solar eclipse: directly or indirectly. Let’s understand them and apply the observation of the eclipse in practice:
1st way – directly: A number 14 soldering glass lens is used to observe the sun directly. Since lens number 14 is hard to find, number 12 can be used, but never below that number. The unit cost of this welding lens is R $ 15.50 (Mercado Libre), but in a physical construction store it can be found at a much more affordable price. Figure 3 shows the photo of the welder’s glass lens and how we observe the eclipse.
Using a soldering iron filter to observe the eclipse.
For observe the solar eclipse using the welding glass lens you need to strictly follow the steps:
1st – lower your head and place the welding glass in front of your eyes;
2nd – raise your head and observe the eclipse for a maximum of ten seconds and;
3rd – lower your head and remove the welding glass.
It is very important to note that if the observer removes the glass lens from the front of the eyes, while observing the Sun (step 2), they will surely suffer from eye pain. For this reason, it is essential to complete all stages, including stage 3.
How to use the welding filter to view a solar eclipse
2nd way – indirectlyIf the observer is afraid to make a direct observation, or cannot acquire the glass lens of the welder, or still wants to show the eclipse to a child, it is advisable to observe the eclipse indirectly. To do this, there are several safe ways, but here I highlight a very interesting one, which is to use a noodle or rice strainer that has holes in the shape of circles. In fact, you can use any object that has a hole in the shape of a circle, and that can even be made on a sheet of paper with a simple needle stick. Then project onto the ground and you’re done.
Figure 4 illustrates how we indirectly observe a partial solar eclipse using a pasta strainer.
