In just two nights, Earth will pass through a stream of debris shed by the short-period comet 209/P LINEAR, which will produce a meteor shower that will radiate from the obscure constellation of Camelopardalis, which is located near the North Celestial Pole. For observers living in the Continental United States (and Alaska), the show will be well-positioned for its 2-4am peak on Friday morning. To make matters better, the Moon will be a non-factor, too.

So, how are things looking in regards to the shower? Well, it depends on who you ask!
First
the certain. Earth will definitely pass through a trail of cometary
debris on the Night of May 23-24, reaching the deepest concentration
between 2 and 4am EST. The meteors will appear to radiate from the
obscure constellation of Camelopardalis, which is located between the
more famous constellations of Ursa Major and Cassiopeia, which are
easy to find for even inexperienced star gazers.
Now
for the unknowns.
For
starters, no one knows how dense this trail of debris is in the first
place, which will have a direct impact on whether these meteors
sizzle or fizzle. Long story short: if there's a lot of junk, there
will be a lot of meteors, a little junk, only a few meteors. This
being a new shower, no one knows what to expect.
Another
interesting possibility: in an interview with space.com, French
astronomer Jeremie Vauballion did some calculations and came to an
intriguing conclusion: all of the trails of debris shed by the comet
between 1803 and 1924 were along roughly the same path, which is the
one Earth will pass through on the night of May 23-24. On the high
end, some estimates place meteor rates at 1,000 per hour, though many
are far more conservative.
However,
other research is
decidedly less optimistic, suggesting that 209P/LINEAR, thanks to its
short orbital period and many trips around the Sun, barely produces
any dust anymore, having shed most of all of what it could shed eons
ago, meaning that, despite all the debris shed for those 121 years
between 1803 and 1924, there might not be much floating in space for
Earth to run into. .
Bottom
line: no one knows what's going to happen until the night of May
23-24 arrives, so hope for clear skies. If you can, stay up (or get
up early) and head out, turn your eyes skyward, and hope for the
best, which could be spectacular.
