Are you ready for the biggest, brightest moon of the year?

- By Patrick May pmay@bayareanew­sgroup.com

The headline used by Travel & Leisure magazine about the big moon this week says it all: “It’s going to look massive.” OK, so it’s not going to be quite as impressive as last month’s Super Wolf Blood Moon, a total lunar eclipse that turned red.

But tonight’s Super Snow Moon still promises to blow your mind, assuming you’re lucky enough to see it in clear skies. Also called Storm Moon and Hunger Moon, because they’re passing through at the chilliest time of the year, this full moon will be closer to us than at any other time in 2019, the report says.

Here are some things to know about the big show:

What is a supermoon?

A supermoon occurs when the moon’s orbit is closest to Earth (called the perigee) and when it is also full, according to NASA. That combo makes this moon very special, as well as very big and very bright.

Are they rare?

Not really. The first supermoon of 2019 was the Super Wolf Blood Moon on Jan. 20-21, and two more supermoons will follow Tuesday and March 21.

What time can we see the Super Snow Moon?

This supermoon will reach its fullest phase early Tuesday over North America. And while the actual full moon will occur at precisely 7:53 a.m. Pacific time Tuesday, the best times to catch a full

moon are when it’s rising and when it’s setting.

So you’ll have two other chances to see this one do its thing. That means three shots in all at witnessing the biggest full moon of 2019: first this evening when it rises in the east, then on Tuesday morning and again on Tuesday evening when it rises once more in the east.

How about in the Bay Area where we’ve had storms obscuring our skies for days?

You’re in luck! The forecast

says today and Tuesday look clear.

How can we best watch?

The first chance to see the Super Snow Moon near the horizon will come close to sunset today, says the Travel & Leisure report. “Watch the eastern horizon for a biggerthan-usual full moon to rise at 4:49 p.m. Pacific time.

Then on Tuesday morning, you’ll get your chance to catch the ... Snow Moon (when it) sets in the west at 6:46 a.m. PST.

However, later that day the Super Snow Moon will put on the third show when it rises in the east at 6:02 p.m. PST.”

How close will tonight’s supermoon be to Earth?

The supermoon will be 221,681 miles away from us here on Earth at the closest point. NASA adds that “it doesn’t often get any closer than that.”

Has the term “supermoon” been around a long time?

The term has only been used in the past 40 years, according to Space.com. but it got a lot of attention in late 2016 when we were treated to three supermoons in a row, the November moon being the closest in nearly seven decades.
