About the FAU Astronomical Observatory

The Astronomical Observatory is housed under a four meter diameter dome on the Boca Raton campus of Florida Atlantic University. We welcome students, faculty, staff and members of the general public to join our scheduled observations or our public viewing events. Our telescope is mounted on a small platform, at the top of stairs, looking out of the roof of our building, over Boca Raton, to space and beyond!

Location and Maps

Location: We are located in South Palm Beach county, on Florida Atlantic University's Boca Raton Campus in the Science Building (formerly known as the Science & Engineering Building), #43, 4th floor, Room SE-434.

Maps: This Google maps link shows our location at: 26 22' 23.85" N latitude and 80 06' 05.05" W longitude. Or use the information on the parking map provided by the campus. Jump to the Parking Locations section on this page, for particular information regarding visiting.


Schedule of Observation Days and Times:

Student's Class Credit Summer Observations:
Solar Observations: Tuesdays: 11:00 am — 1:00 pm
Night Observations: Fridays: 8:00 pm — Late

NOTE: student credit is not offered for public viewing events, please read below.

Public Viewing Night Observations:
Our twice a month Public Viewing sessions are regularly scheduled on the 1st Friday and 3rd Tuesday of each month. However, this schedule may get altered due to an events that has a particular astronomical significance. The start times for these public sessions are the same as those listed above. Schedules that become altered due to an event of astronomical interest will be discussed about on the Front Page of the website and will be listed in our Events Calendar.

These is no charge for these Public Viewing sessions. While anyone may attend these viewing sessions, students should not expect to receive credit for these sessions.

Please note that night sessions are conducted in our night mode, which uses all red lights. We do this to avoid blue lights, which oversaturates our rod sensing cells in our eyes, temporarily degrading our night or scotopic vision. Night vision is what people use to see the faint nebular fuzzies up in the sky, and it takes about 40 minutes to build up to its full strength. As white light contains blue in it, we need to avoid it as well. So, please, turn off cell phones and PDAs for your own and other's sake. If you need to take flash photographs, please use a red filter on the flash. Thank you.


Details on the Class Credits for FAU Students

We currently offer extra credit for FAU students' Intro to Astronomy class. The amount of the credit offered is 4 points for a night session and 2 points for a solar session. Though students may come as often as they like to any of the lectures, attendance is accredited only once per semester. We record your attendance with a sign-out sheet. Observation sessions continue throughout the semester, however once finals start, the observation sessions for credit for that semester ends as students should focus their energies on their examinations.

The lectures will be provided even if the weather does not provide favorable conditions for star gazing. As the lectures begin promptly, please show up on time so you can follow the discussions.

If you can not make the regularly scheduled observation time, you can contact me for an appointment, however, you do not need to make an appointment for an already scheduled session.

And yes, your friends and/or family may attend the sessions, after all, it is their universe, too!


Planning a Visit?

Are you planning to come for a visit? Some folks have come to visit from a rather long distance only to be surprised that they can not see what they wished to see. To prevent disappointments from your trip, here are a few simple tips to check out before you come:

1.) CHECK THE WEATHER. The General Sky Conditions links on the Observatory's Front Page include weather conditions as well as information about what is up in the sky. The Clear Sky Clock for Boca Raton provides information for the sky conditions for astronomers. In general, the darker the square for the described hour, the better the conditions. Clicking on the colored block bar of the Clear Sky Clock leads to more in depth coverage. The three conditions to look for are:

  • Cloud cover - If you can not see the stars due to clouds, then you can not see them through an optical telescope either. Microscopic water droplets in clouds act like lenses, reflecting, refracting and redistributing light, which blurs stellar images. Radio telescopes can "see" through clouds, but we don't have those.
  • Transparency - Describes the atmosphere's clarity due to a lack of humidity, better transparency means better viewing for nebulae and galaxies.
  • Seeing - Describes the atmosphere's stability, a less turbulent sky means better viewing conditions to see the details in planets.

2.) CHOOSE YOUR CLOTHING FOR THE WEATHER. While the Observatory is inside the campus's Science Building, you will experience outdoor conditions when the dome's doors open to the outside for there is no glass separating you from the outdoors. A glass covering could not be made well enough to avoid disturbing a telescope's view. Domes need to be open for some time so that the temperatures can stabilize with the outside, otherwise, convection (where hot air moves up as cold air moves down) occurs. Looking at a star, while the air inside of the dome convects with the outside, shows a disturbed view of the star, just like looking through a mirage across a hot road on a summer's day or up at a light from the bottom of a pool. To avoid this, the dome is opened so that the air temperatures equalize and becomes more stable. Thus, it may be rather hot or cold in the room when you come.

3.) CHOOSE YOUR CLOTHING FOR COMFORT AND DECENCY. Ladies, I do not recommend heels nor skirts. The stairs to the platform are steep and you may have to wait a while on them for your turn. And then once you are there, you may have to deal with the uncomfortable idea that there may be people looking up at you from the room below. I suggest you plan accordingly.


Parking Locations

FAU tag holders can regularly park in Lot 4 after 6 p.m. for night observations. The parking restriction of faculty and staff only for the Lot ends then.

Visitors to FAU's campus who want to attend a public viewing night observation, parking is now permitted to you in the same Lot 4, just outside the Observatory, from 7:30 p.m. to 2:30 a.m.

A map of the Campus with parking information came be found at this link here. We are on the eastside of the roof of building 43, which appears near the center of the map. A closer view of the new parking lots and roads can be accessed at this link here. In this image, our building and the Observatory on the top appears here on the far left side of the image.

Outreach

We have welcomed many different groups to come to visit our observatory, from school classes, to extracurricular groups and day camps.

On cloudy days or evenings, we will still have lectures or video presentations to offer our visitors.

For those that can not make our Public Viewing events, there are various astronomical viewings offered locally, to the public, such as in:


Equipment Information

We have a new 14 inch Celestron Edge HD Schmidt-Cassegrainian telescope that is mounted on a new Losmandy Titan 50 Equatorial Drive system. Plus, we have upgraded to a new Daystar 0.5 Quantum Professional Edition Hydrogen-α filter. This offers us an image uniformity that has a peak transmission guaranteed within a FWHM of 0.5 to enable us to see prominences "live" on the Sun's chromosphere. All of these new additions were made possible by FAU students through a grant from the FAU's Technology Fee.

Thank you, students!

This is something that you and the community will be able to utilize and enjoy for years to come!

As the observatory does not have its own foundation and suffers from image blurring vibrations from the building's machinary or from people, we have mounted our telescope and equatorial drive on pedestal that incorporates a newly and rather uniquely designed (and continuously worked on), vibration dampening system. This system is uses an interalized weighted "keel" with a vibration dampening, "wiffled" tube, which sits in about 7.0 gallons of a highly viscious silicone oil from Dow-Corning. The top end of the keel is attached the top plate of a set of parallel plates that sandwiches a set of helical isolating springs and bricks of lead, as seen in the image here. The lead provides the inertia for the springs to work against as the vibrations come from below. Very much like the shock absorbers on your car, the majority of the car's mass rests on top of the absorbers. When your car hits a pothole, the shocks push your wheels down to help keep the rest of the vehicle moving evenly along.

Off-
centered parallel plates sandwiching helical isolator springs and bricks of lead to support our telescope and equatorial system and
dampen out building vibrations.

The keel hangs down through a large hole in the bottom plate, so it is not connected to it. The sandwiched springs absorb some of a vibration's shock energy. The energy that does pass through them will cause the keel to move or oscillate a bit, which then will have to move through the viscious oil. The oil causes drag forces on all of the keel's surfaces, which dampens out the vibrational energy. The added dashpots help slow down side to side tilting. Yes, you can still make the telescope shake if you try to, but the shaking comes to a stop much faster now than it ever did before. This design was suggested by FAU's machinist Jeff Webb and then worked on Jeff and by FAU's other machinists Fredrick Knapp, Mark Royer, and myself.

We also have the following accessories for our telescope: a Losmandy Gemini Computer for deep sky objects, a Spectroscopic filter, CCD cameras, a new Broad-Spectrum Solar filter for the new telescope to view sunspots.

Finally, we have also started a collection of meteorites for display. If you wish to learn more about meteorites, I would recommend a visit to Washington University in St. Louis.
