I looked those up and they are not what I am seeing. It is relatively small, figuratively speaking, with a kite-like configuration with a tail of stars. Can only be seen from Louisiana in Nov. Dec. and January, basically. Appears on the eastern horizon, travels westward over the months, rising higher each month. I don’t know if it is a part of a larger constellation. Orion and the Big and Little Dippers are the only constellations that live up to their names, for me.
You have several choices,
If it is small, it could be the Pleiades. Very small cluster in the constellation of Taurus. Taurus itself does have a kite shape and is well up in the east at Sunset.
Auriga, Perseus, Andromeda, also fit.
If it is below Orion, it is Lepus. Small constellation, has some nice objects in it.
Look at the larger version of the photo and see if you can see your group of stars. I can make out Lepus easily in it.
AS for the photo, That is Orion in the middle, so, not many of those meteors are Leonids. Maybe Orionids. The explanation in the article sounds kind of bogus.
Oh OH! I think I got it, it’s the Hyades. It’s the closest cluster to us and is quite nice to look at. The star Aldebaran is in the top left of the group, but, not associated with it.
Give me more info if you can.
