Secret to see the most special "Blood Moon" in the 21st century

In the evening of April 4 , when the Moon rises at the eastern horizon, Vietnamese people and residents of some parts of the world have the opportunity to observe the phenomenon of total lunar eclipse. is the first "Blood Moon" in 2015.

At this time, the Earth's darkness will completely cover the Moon in a very short time, only about 4 minutes 43 seconds . The moon will no longer have the usual yellow color, but instead will be blood red. According to statistics, perhaps this is the shortest total eclipse of the 21st century.

Except for Europe, Africa and a small part of Asia that is not observed, the remaining regions can observe the lunar eclipse this time (in whole or in part).

Countries in North America and Australia and East Asia will have the most favorable conditions to observe this event. This full eclipse of the observation area and the observation time in our country are similar to the previous full eclipse of October 8, 2014.

However, this whole lunar eclipse was quite special because it took place at a time when the weather was more favorable, and the full moon took place higher than the horizon, convenient for observation.

The schedule of the Blood Moon phenomenon on April 4 (Vietnamese time).

1. The moon enters the shadow of the darkness at 16: 00 '
2. Begin partially brewing at 17h15 '
3. Start full phase at 1857 '
4. Maximum reach at 19h00
5. Finish the full phase at 19h02 '
6. Partial finish at 20h44 '
7. The moon comes out of the shadow half-dark at 21:59 '(completely finished)

In Vietnam, the Moon's rise on this day is 17h25 ', which means that we cannot track the phenomenon before this time. In addition, observing the Moon right at the horizon can only be done with people in coastal areas.

Thus, for the majority of people living in Vietnam, the time to start observing the phenomenon will start after 18:00 (when a full phase has taken place) and can be observed completely until eclipse end.

* Attention points need to "pocket" when you view the total eclipse:

1. The real moon is only noticeable since the partial phase begins, because when the Moon phase is half dark, the Moon is only slightly darker than the normal full moon, and there is almost no difference. Also by observing the Earth's shadow covering the surface of the Moon we know that the Earth is spherical.

1. When observing Moonlight, we can completely observe with the naked eye without any eye protection device . However, observing the moon is more interesting when using binoculars and small telescopes, to clearly see the red surface of the Moon.
2. Choose a well-ventilated location, have fresh air, little smoke and smoke away from the urban lights as much as possible.
3. If watching is not enough and you want to save these memories, you need to pay attention to the light, the speed of the camera or smartphone .

1. To shoot directly with a smartphone, you should place the phone on a firm position or on a tripod, this will prevent the camera from shaking due to hand and can be taken at very low speeds without the image being blurred. .
2. You should not use zoom mode in the phone because it does not solve any problem other than reducing the detail of the image - just shoot normally and zoom in after post-production.
3. Travel cameras have an advantage over phones with optical zoom capabilities (from 3x to 60x depending on type). Set it to full or semi-automatic manual mode .
4. Iso varies dynamically depending on the brightness in the phases of the Moon; Place the device on a level or tripod to be able to shoot at low speed, focus on infinity, take a self-timer after a few seconds to avoid hand shake.
