A partial lunar eclipse can be seen when only part of the moon’s surface is obscured by earth’s umbra.A penumbral lunar eclipse occurs when the moon travels through the faint penumbral portion of the earth’s shadow.Where would people be able to witness the lunar eclipse?People in much of North America, South America, South/West Europe, much of Africa, Indian Ocean, Pacific, Antarctica and Atlantic will be able to watch it.However, it will not be visible from India as it is taking place during the day.When can people watch it?The penumbral lunar eclipse will start at around 8.37am IST on July 5 and will go on till 11.22am IST.
