Spring Break 2012 Special Programs Schedule

Currently up to 60,000 visitors each year participate in the variety of public observing activities conducted at the Visitors Center Public Observatory, including Solar Viewing and Star Party programs. Many of the instruments available for public use were donated to the facility by individuals, companies, and institutions seeking to promote interest in astronomy.

Large groups planning on visiting the Observatory and/or joining any of our public programs should notify the Visitors Center prior to the visit.

The Visitors Center is open daily from 10:00 A.M. to 5:30 P.M (additional hours on Star Party nights), and closed only on Thanksgiving, Christmas, and New Years Day.

DRESS WARMLY!!! Temperatures vary quite a bit at our elevation (6,300-6,800 feet above sea level) and are usually much cooler than other areas of Texas. The mountain air can cool as much as 20 degrees after sunset and most of the Star Party program takes place outside under the stars. For summer make sure you bring at least a light jacket and long pants. For Fall, Winter, and early Spring programs, layer your attire and bring a warm coat, thermals, gloves, and something to keep your head warm.

Daytime Activities - Included in the "Daytime Pass":

• Explore the "Decoding Starlight" Exhibit Hall at the Visitors Center and enjoy various astronomical presentations in our multimedia theater.
• See our nearest star, the Sun, from the comfort of our multimedia theater during our Solar Viewing program. View sunspots, flares, and prominences safely as they happen live. In the event of cloudy conditions, we will provide video of the above, taken with our telescopes.
• Join our Guided Tour for an up-close look at large research telescopes at McDonald Observatory. The 90-minute tours are led by knowledgeable guides who will give you insight into the workings of a professional scientific research facility. A portion of the Tour takes place outside, so please dress appropriately. Even during summer, wind at the summit can make a warm day seem unpleasantly cool.

Twilight Programs

Our Twilight Programs are engaging, 60-70 minute learning experiences which take place on Star Party nights only. These programs are separate from and do not include the Star Party, although you may do both if you wish...many people do.

In our current Modeling the Night Sky Twilight Program, you will learn about planets - where to find them, where not to find them, and why they move and change in our night sky from week to week. We will also construct, using the program participants, a more-or-less scale model of the solar system. This program is $5 in addition to the Star Party.

This program utilizes both our indoor theater for visualization, and our outdoor amphitheater.

This program are great for all ages. Dress warmly...half of the Twilight Program takes place outdoors.

During Summer, Spring Break, and other holidays, the Twilight Program tends to sell out early ... sometimes even before the day of the program. Those with reservations should plan to arrive at least 15 minutes prior to the program start time (bring a copy of your reservation confirmation.) If purchasing your Twilight Program passes at the Visitors Center (we strongly encourage making reservations in advance online instead) plan to do so between 10:00 a.m. and 5:30 p.m. We do not encourage planning to purchase Twilight Program passes immediately prior to the program during busy times of the year.

At our discretion, we may change the content of the Twilight Program without notice.

Evening Star Party - Included in the "Star Party Pass":

• Enjoy a tour of the constellations and view the moon, planets, stars, galaxies, and other objects through large telescopes at our Visitors Center Public Observatory. The program is fun for the entire family, and is open to everyone. In the event of rain, significant clouds, or high winds/dust/humidity, a series of unique indoor presentations will stimulate your interest and curiosity; refunds due to inclement weather are not available. The StarDate Café and Gift Shop open one hour before the Star Party.

DRESS WARMLY!!! Temperatures vary quite a bit at our elevation (6,300-6,800 feet above sea level) and are usually much cooler than other areas of Texas. The mountain air can cool as much as 20 degrees after sunset and most of the Star Party program takes place outside under the stars. For summer make sure you bring at least a light jacket and long pants. For Fall, Winter, and early Spring programs, layer your attire and bring a warm coat, thermals, gloves, and something to keep your head warm.

When should I visit for a Star Party?
Although there is no single best answer to this question, one of the more important things to keep in mind is the phase of the Moon. With the Moon at any phase between several days before First Quarter and 3 or 4 days past Full, bright moonlight limits our ability to observe faint objects but, of course, gives us great views of the Moon itself. At the U.S Naval Observatory data service site, you can find lists of dates of the four major moon phases to help you make your plans.

We can't predict the weather if you're visiting us weeks or months in the future (although some have asked); however, if your Observatory trip is this week, you can use Weather Underground to see our local forecast.

We also offer Special Viewing Nights on the 107" and 36" research telescopes, and a Lunar Viewing Program specifically designed for fantastic views of the Moon, our nearest neighbor in space.
