Be kind to your neighbor. Turn off, dim, control or shade your outdoor lights please. There are great lighting tips for those who live in the valley on our Light Pollution flyer
The Night Sky Friendly Business program recognizes those with appropriate outdoor lighting. Businesses and organizations can show their support for the very popular Dark Sky Community designation by being Night Sky Friendly.
Merit winners receive a certificate and window sticker; they may use the Dark Sky Friendly Business logo in their advertising; may receive publicity in the press; are listed on this website and on a plaque posted in the Borrego Springs library in recognition of responsible and environmentally sensitive approach to preserving the beauty of Borrego’s night sky for all to enjoy. Any business or organization with a physical presence in the Borrego Valley may apply using the Business Application form which is available here or may be requested by calling 760-767-3052.

For more information on Dark Sky compliant lighting, download our Lighting Standards for the Borrego Valley.

For appropriate lighting, Dan Wright (left), owner of The Springs RV Park and Resort, accepts the Dark Sky Friendly Business certificate from Borrego Dark Sky Coalition member, Jim Rickard.

Borrego Springs is the only Dark Sky Community certified in California by the International Dark Sky Association. This recognition brings many visitors to the valley, seeking a view of the stars which is no longer visible in most urban areas.

On February 26 Mars will be nearly on top of Uranus, but binoculars are needed to see Uranus..

On March 18 Venus and Mercury set together soon after sunset. Mercury is a hand width to the south of Venus.

Jupiter is at its brightest, up in the evening sky in April. Beginning late April Venus rises to the east in the mornings, out shining Saturn which is overhead.

The Lyrids meteor shower is worth watching April 22 after 10:30 p.m., but best for a few hours after midnight. Thin crescent moon provides optimal conditions. You can expect to see 16 to 25 per hour. These meteors occasionally produce bright trails that last for several seconds.

Eta-Aquariids meteor shower, made up of dust shed by Halley’s Comet, can produce “shooting stars” from April 19 to May 28. The maximum on May 6 faces some moonlight however.
