Families are welcome, and the kids will have a great time with hiking, swimming, fishing, canoeing and basketball available among many other daytime pursuits. The AAAP website has the registration form. Opportunities for AAAP Members. The AAAP has a threefold mission of supporting hands-on astronomical observing and imaging by members, cutting-edge lectures by professional astronomers and physicists, and public outreach and education in astronomy. To reach our potential requires energy, effort, and commitment of the membership. We have evolved a structure to develop and coordinate the activities in the club, and are seeking input and participation in all facets of the club's activities. Please think about how you can "give back" to the AAAP, your peers, and to amateur astronomy by contacting me or other Board members or committee chairs to help build on our foundation.

school year. Astronomers commit to making at least four visits to the same one or two classrooms or youth group. A class visit usually is 60-90 minutes. During these visits astronomers answer students' questions and lead or assist the teacher with astronomy activities. Examples of activities include: Making a Telescope, Stargazing, Exploring the Constellations, the Reason for Seasons, Modeling the Phases of the Moon, Making a Scale Model of our Solar System, Observing the Moons of Jupiter, Making a Comet, Life Cycles of Stars and the Origin of the Universe. Many of our astronomers are finding participating in Project ASTRO NOVA so rewarding and enjoyable that they make several additional visits. Astronomers who are interested in participating in Project ASTRO NOVA should request and fill out an Astronomer Volunteer Form. On this form, astronomers will be asked for areas of astronomy that are of special interest to them and which grades/ages they prefer to work with. Based on this information, astronomers will be matched with compatible teachers or youth leaders near their home or work. Astronomer Volunteer Forms and more information can be obtained from our website at http://www.raritanval.edu/ planetarium/astronova/ or from Project ASTRO NOVA, Raritan Valley Community College, P.O. Box 3300, Somerville, NJ 08876, (908) 231-8805, fax (908) 526-7938, or email Amie Gallagher at agallagh@raritanval.edu. The deadline for submission of Astronomer Volunteer Forms is June 1, 2004.

Astronomers Needed For Project Astro Nova Meet The Best Audience You Have Ever Had: Our Children!
This is what astronomers have said about Project ASTRO NOVA: "The kids quickly warmed up to me, I settled right in" "They were great, well behaved and so full of eager questions", "The questions never stopped, the thinking never stopped, and of course, the learning never stopped", " I learned just as much as the kids", "Thank you for giving me the opportunity to share my fascination of this subject with some very wonderful children", "Participating in Project ASTRO NOVA has been a real life-changing event", "A truly stellar experience". If you live or work in New Jersey and like to share your enthusiasm and interest in astronomy with our youth, Project ASTRO NOVA is for you! Each school year Project ASTRO NOVA pairs 2nd to 12th grade teachers and youth leaders with volunteer astronomers. In the current school year we have 52 astronomers who are partnered with 83 enthusiastic and committed teachers. Some astronomers are paired with two teachers at the same school. Project ASTRO NOVA prepares and helps its astronomers from start to finish. Astronomers first meet their partner teacher at the training workshop where they are engaged in effective classroom-tested hands-on astronomy activities that meet the NJ State Science Standards. During the workshop partners develop a strategy for working together, in and out of the classroom, and start planning the astronomer 's visits. This year we have scheduled our workshop on Friday-Saturday, October 1-2 at Raritan Valley Community College. Each partnership will receive a wide variety of materials and resources for use in their visits, including: The Astronomical Society of the Pacific's "The Universe at Your Fingertips" activity and resource notebook, articles about recent astronomical developments, resource lists, access to audio-visual materials, tips on working with schools/groups and students, tips on addressing and working with preconceptions and learning styles, and more. Class visits usually start in the fall and continue through the

From the Treasurer:
The treasury balance is $XXXX. There are 122 paid members. Note: Please do not contact Sky and Telescope for a club discount subscription. This arrangement will start in August 2004. If you want a subscription now please contact me. I have been contacted by Sky and Tel on several occasions about members calling for club discounted subscriptions now. Sky and Tel cannot verify your membership without a current membership roster, which we will be doing in August. Sky and Tel has extended the courtesy of letting us renew our subscriptions at club rates without going through the club. Let us not abuse this. Also found out from a call that Anthony Sosso made to Astronomy that they will now honor a club discount rate when called. Just state that you are a member of the AAAP. Bryan Hubbard, our publisher, will continue putting the dues renewal date on the upper right corner of each Sidereal Times address label. This is the date that your renewal membership is due with the AAAP. This will cease when the club goes to the once a year membership. I am not going to send out renewal notices to members who get magazines; they get enough notices from their respective publishers. If I don't receive you renewal on the date indicated on your address label you will be dropped from the roster. If you are a keyholder, the respective observatory chairman will be notified and you will be asked to return the key. Note! Starting in April, dues will be $20 until June. The dues (Treasurer, continued on page 3)


(Treasurer, continued from page 2) structure is a follows: $20 basic membership. $50 for membership and subscription to Astronomy magazine. *$53 for membership and subscription to Sky and Telescope magazine. $83 if both magazines are desired with membership. *Recent increase of Sky and Telescope magazine. If you have a Sky and Tel subscription please send the subscription notice and the postage paid envelope when renewing your membership. This service will be provided until August. You may send the dues directly to me at: Ron MittelstaedtTreasurer, 149 Palmer Lane, Ewing, NJ 08618-3207 Ron Mittelstaedt

Letters to the Editor
I thought I would drop you a quick note to tell you of my experience with Astronomy Magazine. In the April issue of Sidereal Times it was indicated that Astronomy would not honor the club rate if the renewal did not come directly the club. I called them and explained how we were cutting back on club administration and asked for the club rate. Initially, they refused and quoted a $39.95, 1-year renew rate. After a brief conversation, Jenny, said she would check with the subscription manager and call back. She promptly called back and offered a $29.95 1-year rate and a $55 2-year rate, saying they did not want to lose club subscriptions. Apparently, my subscription was one of the first of the 25 club subscriptions to come up for renewal. She noted in their records that anyone identifying their selves as AAAP members would get these rate options. I thought you might want to pass this information to other club members Regards, Tony Sasso

From the Webmaster
Take a peek at the sensational image of NGC 4565, taken by AAAP member Brian Van Liew, on the AAAP homepage. Wow! Brian created this using our Celestron 14 at the Washington Crossing observatory. He worked with a Starlight Express MX716 camera, configured with a 3.3 focal reducer. The exposure equaled 30 minutes total (30 x 1 minute), unguided. The image was processed with AstroArt 3.0. This edge-on SAb type galaxy in Coma Berenices is about mag 9.6v and about 14' across. It lies about 31 million light-years distant. Captions for any photo can be seen by mousing over the image. Also found on the front page is a photo of some AAAP members who attended the Northeast Astronomy Forum last weekend in Suffern, NY. Sponsored by the Rockland (NY) Astronomy Club and Sky Publishing Corp., this has become the largest amateur astronomy vendor event in the country. Click on that photo, and you'll be transferred to a gallery with many more pix of the event. Speaking of events, astro-activities start to warm up with the weather. Although many of us wish the weather would dry up as well. April 30 is the date of the next AAAP open house at the Washington Crossing observatory. Details are on the web site. The FitzRandolph Observatory, housing a 36" Cassegrain, on the Princeton University campus, is also holding an open house on April 30th. Fill the car with expensive gas, and make the night a double header! And, of course, Jersey StarQuest, our annual star party, begins Friday, June 18. Don't wait to send in your registration! You'll find all the details on the website including directions and registration form. This year 's keynote speaker is Michael Shara, astronomer at The American Museum of Natural History. Two regional Truss Dob manufacturers will be on hand with their big guns. You'll enjoy lots of astronomy talk, a forest of scopes, fully catered meals, jugglers and great raffle prizes. Well...all right. No jugglers. The club website is: www.princetonastronomy.org Good Surfing, John Miller

The best way to get to the observatory is to take Interstate 95 South towards Pennsylvania. Then take Scotch road at Exit 3 and proceed north (this amounts to right). Then, at the third traffic light take a left onto the Washington CrossingPennington road (County Route 546). Take this road to the first traffic light and take a right onto Trenton-Harbourton road (County Route 579). Take this road to the first driveway on the left, this is the Phillips Farm/Soccer Field entrance to the park. There is a series of three gates with club combination locks. If the gates are not open, you will need the lock combination to open the gate or be accompanied by a Keyholder member.
