A total lunar eclipse...
[h=1]Coming today: A super blue blood moon[/h][h=2]There hasn’t been a lunar trifecta like this in many years, and the next won’t occur in a hurry either.[/h]

On Wednesday, much of the world, including India, will get to see not only a blue moon and a super moon, but also a total lunar eclipse, all rolled into one. There hasn’t been a lunar trifecta like this in many years, and the next won’t occur in a hurry either. The eclipse will be visible best in the western half of the US and Canada before the moon sets early Wednesday, and across the Pacific into Asia as the moon rises Wednesday night.
The coincidence of Wednesday’s blood moon with other astronomical events is what makes this event special. A blue moon means it is the second full moon to occur in a month; and a supermoon means it will be closer to the Earth than usual.
Blue and Blood
As is well known, “blue moon” is just a name — the moon won’t turn blue tomorrow (or at any other time). Rather, during the peak total phase of the lunar eclipse, it will have a reddish or coppery tinge. This is becaue even though the moon is in the shadow of the Earth, some light does reach it. Fine particles in the atmosphere scatter the blue component of the solar spectrum, and what reaches us is the longer wavelength red light.
