Merlion Wayfarer read from Earth Sky that the moon on these two nights will be blue.
There are different definitions for Blue Moon. By popular acclaim, Blue Moon refers to the second of two full moons in a single calendar month. A Blue Moon might also be the third of four full moons in a single season – a season being defined as the time period between a solstice and an equinox, or vice versa. Or, someday, you might see an actual blue-colored moon. A Blue Moon falls on the night of August 20-21, 2013. It’s a Blue Moon by the seasonal definition, that is, the third of four full moons to take place in a season, in this case between the June 2013 solstice and September equinox. The last Blue Moon by this definition happened on November 21, 2010.
This is the moon last night - the first shot was taken with Auto White Balance and the second one was taken with the Daylight mode, which more accurately reflects the colour of the moon...
Definitely no blue enough. Oh well, Merlion Wayfarer will be on the lookout again tonight!
