Meeting Time and Location Pick a day of the week that you know isn't crammed full of lectures for most students. Don't choose Monday or Friday if it can be avoided - on Monday most people are recovering from the weekend and on Friday many students leave the campus early to party. Pick a time of day when many students are on campus, yet that isn't too early or too late in the day. Remember, most people avoid being on campus before 10am and like to leave campus before dinner time. Generally, lunchtime, or between 4-6pm is good.
Location is very important.
Find a room that is large enough to accommodate about 30 people, has many couches and comfortable chairs, audio-visual facilities, and a nearby kitchen where refreshments can be prepared. Don't pick a lecture hall, unless you know your guest speaker or film is going to attract a large crowd. It looks silly when there are only ten people in a lecture hall that can accommodate 300. The room should be familiar to students and faculty - not an obscure room in the basement of an obscure building. Generally, a student commons room in a science building is a good choice because it will attract students who are probably already interested in space - the science student population.
