How to see the Delta Aquariid meteor shower
Part of the reason for the low meteor rate with the Delta Aquariids is, as mentioned above, the radiant is low in the southern sky. Because of that, you'll want to watch from somewhere with no obstructions along the southern horizon. If there are buildings, trees, or hills in the way, they'll probably obscure some meteors from sight.
Though Aquarius will be low in the sky, you should locate it to help you see the most meteors possible. Look toward the constellation, but not directly at it. The meteors will be moving away from the radiant.
As with any meteor shower, you want to get out of the city and toward a viewing space with dark skies. The darker, the better. National Parks and State Parks are a good place to start looking for a place to stargaze in your area.
If you're not enticed by a meteor shower with obstacles, you're only a few weeks from the best meteor shower of the year. The Perseids will peak the night of August 12. It's this year's Super Bowl of meteor showers. (Here's a list of Perseid meteor shower viewing parties in every US state.)
Though, like many meteor showers in 2019, the Perseids will be competing with a bright moon. However, the Perseids actually begin in July, even if you won't see nearly as many meteors as you will around its peak. So, if you're out hunting for the meteors of the Southern Delta Aquariids, you may be able to spot a few streaks of light that are part of the Perseids. That shower has the constellation Perseus as its radiant. That can be a little tricky to find for a casual stargazer. But just to the north of Perseus, you'll find the more easily recognizable Cassiopeia the Queen, which is roughly in the shape of a tilted W or the number 3.
No matter what you're looking for, tonight should be a great evening to be out looking up at the night sky.
