What will happen on 10 December 2011 ? What are its timings astronomically?
A Lunar Eclipse occurs when earth in course of its orbit around sun, comes between moon and sun such a way that moon his hidden in the shadow cast by earth. This can occur only when the Sun, Earth, and Moon are aligned in a straight line, Hence lunar eclipse occurs only when there is full moon.
So on 10th Dec, 2011 Total Lunar Eclipse will occur. Eclipse in various phases begins at 5.02 p.m. and Ends at 11.02 p.m. on 10th December, 2011. The noticeable Umbra phase begins at 6.15 p.m. and Ends at 9.48 p.m. wherein Total Phase begins at 7.36p.m. and ends at 8.28 p.m.
Astrologers are reporting 6 p.m. to 9.48p.m. Why do you say eclipse is upto 11 p.m ?
Though astronomically speaking Eclipse begins at 5.02 p.m. with moon entering lighter Shadow of Earth. People can noticeably witness darkening ( or leaving) of Moon’s disk between 6.15 p.m. to 9.48 p.m.
This can be further explained by explaining what is Penumbra and Umbra
Earth’s shadow has two parts Penumbra (outer lighter part) and Umbra (darker part). All Lunar Eclipse begin with moon first entering penumbra at one end passing through umbral phase and ending with leaving the penumbra on other end. Generally only the Umbral phase is commonly considered as actual eclipse by general public to follow various rituals and traditions leaving Penumbra passage of moon. Whereas all Lunar eclipse begin and end with moon entering and leaving the penumbra (lighter outer shadow of earth).
What is this totality phase?
Importantly moon will be completely immersed (for 52 mins long) in the dark shadow of earth from 7.36p.m. to 8.28 p.m. during Totality Phase. Whereas from 8.29p.m. Onwards one can notice moon slowly coming out of the shadow of earth returning to brightness.
You said 52 Minutes totality Phase is Longest till 2018 ? Why ?
Yes If Totality Duration data is seen Total Lunar Eclipse on 10 Dec, 2011 is longest (52 mins), compared to 8 Oct, 2014 (29 mins) where only 6 minute of partial phase is only visible in India, 4 April, 2015 (5 mins), 31 Jan, 2018 (76 mins) , 27 July, 2018 (103 mins). Conclusion: so Eclipse on 10 Dec 2011 is longest till year 2018 27 July.
When is the next Visible eclipse from our country ?
Next opportunity to see a Eclipse will occur on 25 April, 2013 which is Lunar Eclipse but its is Partial Lunar Eclipse..But to see Total Lunar Eclipse one needs to wait till 2018.
What is other unique point of this Eclipse ? You said 2018 what does that mean ?
So 2018 July 27 is the only time when people can see entire umbral phase including whole of Total phases just like in case of 10 Dec 2011.
Can you explain this again?
In simple words a person from India and neighboring country if misses to see Eclipse on 10 December, 2011. He has to wait till 27 July 2018 for seeing eclipse in various visible phases totally.
Which if we can see here
Though there is Total Lunar Eclipse on 8 Oct, 2014 people in India & around can see only a part of moon covered that to 6 minutes only towards end of eclipse due to moon which rises at 5.58 p.m. On 4 April, 2015 due to late rising moon (at 6.28 p.m) the total phase is already over at 5.28 p.m to 5.33 p.m. On 28 Sept 2015 eclipse occurs after sunrise hence we can’t see. Whereas in 2018 on 31 Jan again due to delayed moon rise people can start seeing eclipse few minutes before total phase where most of moon is engulfed in Earth Shadow.

India is one of the best places to see this eclipse totally because the eclipse in its various phases (start to end) is visible.
