Close up of search light

In March, 2008, Murrieta Valley Mitsubishi started using search lights to advertise. This use of searchlights is occuring within 30 miles of Palomar Observatory and is a violation of Murrieta's municipal code (from see Section 16.18.100, Lighting; G. Prohibitions; 4.: "Operation of searchlights for advertising purposes is prohibited.").

Aside from the violation of municipal code, this activity if offensive to amateur astronomers and to anyone one who enjoys the night sky. Mitsubishi is essentially saying that the sky is their advertising space.

Mitsubishi should be reminded that amateur astronomy is quite alive in this community. Each year, local astronomy clubs set up telescopes for thousands of visitors. A star party for a local cubscout pack is planned for March and another for the entire community in two months. Do these groups need Mitsubishi's permission to use the sky?

It should be noted that while taking these photos, no customers came or went. But of course, it's hard to prove a negative.

Billboard using, perhaps, more light than is needed for the message (Note: Venus is visible).

This blank billboard remained lit from the week of February 10, 2008 to March 7, 2008.
