A Super Blue Blood Moon, a Wordy Wonder

A couple of nights ago a rare lunar event called the “super blue blood moon” dazzled us here in Rajasthan and many others around the world. Here in India, this event was scheduled to occur just after sunset which made it all the more vivid and magical to see with the naked eye. Our JAWAI skies are without a doubt pretty mesmerising on a daily basis, however what we were about to see was something truly spellbinding. To our west we had a beautiful red lit sky painting the rising moon in the east in a warm, fire burning red. So what exactly is a Super Blue Blood Moon other than a bit of a wordy wonder?!

Let’s break it down. Firstly, lets start with the super moon. When the moon is joined with the word ‘super’, it doesn’t necessarily mean astronomers believe it to be utterly fabulous at that point in time (although I’m sure they always think the moon is.) It is called ‘super’ because the moon appears particularly large in the sky and it happens when the full moon coincides with the moon’s closest approach to Earth in its orbit. Supermoons make the moon appear a little brighter and much closer to us on earth than normal.

 

Now for the blue moon. A lunar month takes roughly 29.5 days. Therefore, when a full moon falls early in the month then there is a fairly good chance that there will be a second full moon in the same month. This second full moon in the same month is called a blue moon. You may have heard the expression: “once in a blue moon”, it reflects an event or action that occurs very rarely as blue moons naturally come once in just under 3 years (although atypically the next blue moon is in 2 months time on the 31st March!)

A “Blood Moon” is the name given for a view of the Moon during a total lunar eclipse, when the earth is positioned between the sun and the moon. When this happens the moon appears reddish in colour as it is illuminated by sunlight filtered and refracted by the earth’s atmosphere. Hence it earns its nickname… Blood Moon.. This glow is produced by the same effect that gives us beautiful red sunrises and sunsets. Sunlight is skimming through the Earth’s atmosphere on its way to the Moon and it gets refracted or bent causing more of the higher frequency light waves (green, blue, indigo and violet) to be scattered while the lower frequency light waves (red, yellow and orange) pass through.

The coinciding of these three magical lunar events is very rare with the last one occurring about 150 years ago (I believe Forbes.com calculated it to occur, on average, once every 265 years) making it all the more special that we were able to enjoy it here at SUJÁN JAWAI.

 

Be sure to keep an eye out for the next lunar occurrences to hit our skies!
