Daily monitor of SpaceX Vandenberg launches viewable from San Diego with naked-eye feasibility assessment.
```
Falcon 9 launch Mon 7:11 PM—poor visibility
Poor viewing conditions — launch occurs 32 minutes before sunset in full daylight, making the rocket extremely difficult to see with the naked eye against a bright sky.
Mission: Starlink Group 17-42
Date/Time: Monday, May 19, 2026 at 7:11 PM Pacific
Window: 7:11 PM – 11:11 PM (4-hour window)
Rocket: Falcon 9 Block 5
Site: Vandenberg SFB, SLC-4E
Viewing assessment:
Sunset is at 7:43 PM, so this launch happens in bright twilight. The exhaust plume will be washed out by daylight. For optimal naked-eye viewing, you want dawn launches (30–90 min before sunrise) or dusk launches (30–90 min after sunset), when the rocket is sunlit against a dark sky.
Why this matters: Vandenberg launches heading south over the Pacific are often spectacular from San Diego when timed right—this one just isn't.

This is your first SpaceX Vandenberg alert. You'll only hear from me when there's a new launch in the next 10 days.
