Port Mansfield Channel
Padre Island NS
Local Relevance
The scientific findings at Port Mansfield Channel provide Raymondville residents with the most reliable data on regional atmospheric stability.
"Set up on the dune ridge adjacent to the channel and approximately 200 meters from the surf line. A couple of campers in the area, though not much in the way of lights. There are two lighted channel bouys (one red and one green) that flashed on and off. Some scattered low clouds to the SE and East. Port Mansfield light dome easily visible to the west and the developments on South Padre Island very bright to the south. The Milky Way was eaily visible though it was washed out in the SW horizon. M31 visible with the naked eye and stars visible to about 5 degrees above the ocean. This was still a nice place to experience the night sky, though skyglow to the south and west definitely impacted my observations."
Palmito Ranch Battlefield NHL
Palo Alto Battlefield NHP
Local Relevance
Raymondville enthusiasts typically use the instrumented readings from Palmito Ranch Battlefield NHL to calibrate their deep-sky expectations for the area.
"Clear view of the Space X complex only 6 miles away. The light dome from Brownsville and Matamoros Mexico dominates the sky to the west and SW. Port Isabel is very bright to the NE, while the Space X complex to the east has significant direct glare sources. The Port of Brownsville contains numerous very bright installations. The Milky Way is still mostly visible overhead, though many features are hard to see. The light domes extend to at least 40 degrees in the west and 25 degrees from Port Isabel. While Space X now exists in an area that was previously devoid of artificial light, it is not the biggest contributor to skyglow in the region, though it's unshielded and extremely bright blue/white light is the biggest direct impact to the Palmito Ranch Battlefield NHL nighttime environment."
