9. In the past, deterrents Light pollution Outdated equipment… (upgrades done over the summers since 2011!) HS interns (2007-2008) 14” My personal 6” UG independent study, AstroTerps (summer 2011, 2012) Past school year teams Possible Asteroids, comets Variable, eclipsing stars Exoplanet transits! Research

10. Research • Brett Morris • Exoplanet transits • Summer 2011 using 152mm refractor • Summer 2012 using both refractors • Variables • Asteroids • Kalliope and mutual eclipse observations • co-author on www.lpi.usra.edu/meetings/acm2012/pdf/6352.pdf • Currently training other students (AstroTerps)

11. Student Teams • High School and college students • Student groups for different topics • SG1 – Exoplanets • SG2 – Supernovae Search • SG3 – Asteroids/Comets • SG4 – Jovian moons and events • … occultations, software, astrophotography,… • 1-2 team leaders per team • College students • Serve as mentors • Will have keys • Announces to team when observing • 4-6 team members • High school students • College students • Training on equipment, techniques, analysis

12. Research • Spectroscopy • Spectra-L200 • SBIG spectrograph • Occultations • Purchased ADVS in 2013 • Future wish list • Weather station • All-sky camera (weather and meteors) • Seeing monitor • Follow a number of Yahoo groups to stay informed of calls for observations • (negative) observation of Pluto occultation (June 2012) • Coordinating with GSFC/UMD research group to get spectra of moon

13. Programs • Classes • Explore the Universe (collaboration between Astronomy, CPS-SDU, NWHS)… transforming how we run this class into our student research teams! • This past spring semester we had 7 SDU students, 2 Phys 299 students, and 3 HS interns. • 2012-2013 we had no students! • ASTR 310 (fall, labs) • ENAE 441 (fall, 4-5 groups) • Intro astro classes ???? • We used to have 110/111 • Currently haphazardly done… TAs … other schools!

14. Programs • Public • Open Houses • 5th and 20th of each month • Lecture, tour of telescopes, observing weather-permitting • Impromptu observing sessions • Short notice via mailing list, social media

15. Programs • Public • Special observing (solar eclipses, transits…) at the observatory or on campus • Group tours • Night: 5th and 20th of each month BEFORE public session of Open House • Day: M-F • Scouts, school classes, retirement home groups, home schoolers, …

16. Programs • Public • New Telescope Owner Nights • 1-on-1 help session • Held in Jan (right after the holidays!) • Learn the Sky Nights • Basics of ‘amateur’ astronomy • 6 nights during the summer

17. People • Staff • Observatory Coordinator (part-time: Elizabeth Warner) • Technical Advisor (part-time: Dr. D. Wellnitz) • Telescope operators (hourly & volunteer, undergrads) • Guest Speakers (faculty, grads; from UMD and other institutions) • MCs • Grad students (“volunteers”) • Volunteers • Special events, large crowds

18. $$$ • Good question! • Comes out of Department overhead (a very nebulous source!) • Student tech fees • Submit proposal to get equipment • ST-10, filter wheel, filters (7”) • Change for 2014 • Observatory fund • Selling used text books, ‘garage’ sales of old equipment, slides,… • Purchased eyepieces, ST-8 (CCD camera), pier mods for 7”, repair of 8”, filter wheel (14”), filters (14”) • Fees charged • Open Houses and most public events are free! • $10/class charged for LTSN to cover cost of ‘goodies’

19. Advertising • No paid advertising!! • Websites • Department: www.astro.umd.edu • Observatory: www.astro.umd.edu/openhouse • Astro in DC: astronomyindc.org • Email • Mailing list (600+) • Messages to local clubs • Social Media • Facebook • Twitter • B. Friedlander’s Sky Watch column in Washington Post • Other misc. articles (The Diamondback, Post Weekend, College Park Patch,…)

20. Collaborations • NCA meetings at Observatory • Email contact with most area clubs and facilities • AstroTerps • Student astronomy club • astronomyindc.org • IYA project to coordinate/collate public astronomy programs in the area. • NASM and most clubs provide input • Also have random input from GSFC and other “pro” institutions

21. Challenges • Getting speakers • Volunteers primarily from faculty in department, but also grad students, scientists from area institutions, amateurs • Over-advertising • Surprise article in WashPost on 4 Sept 2009 (Labor Day weekend) resulted in 300 people showing up to Open House on 5 Sept… we have seating for 75! • Deteriorating buildings
