I got a note from our daughter Lillian this morning.
Here's what she said:
I read an article the other day about how a blue moon is technically the second full moon within a month, which isn't all that rare. However, they say that you can actually get a real blue moon, one that actually looks blue, if there is a lot of smoke and ash in the air.
So you two should put on your masks on Thursday night and go look at the blue moon.
