Information about this eclipse
This image shows the global map with two regions: the shaded region where you can not see the lunar eclipse, and the blank region, where it can be seen. The image details the type of eclipse, the magnitude of the penumbra and umbra, Saros series to which this eclipse belongs, among other data. The date and time displayed in this image are international date and time, therefore, they might not apply to your country.

You can read the table above as follows: On January 21, 2019 in Nukuʻalofa, Pacific/Tongatapu (UTC 13), an total lunar eclipse will start at 15:37, the maximum eclipse will occur at 18:12 when the Moon reaches an altitud of -17°;this event will come to an end at 20:48 and will have a penumbral magnitud of 2.168 (this is the fraction of the Moon obscured by the entrance to The Earth's penumbra) and an umbral magnitud of 1.195 (fraction of the Moon obscured by the umbra of The Earth).
We must take into account the altitude of the moon, for example, in Nukuʻalofa, due to the low altitude of the Moon (-17 degrees) this lunar eclipse will not be very obvious.
