President's Message...
As most of you have heard, this will be my last President's message. Family responsibilities must take a precedent in the coming year, and yet the club must go on. We placed our utmost faith in the nominating committee and they have done a fine job. I know that you will join me in supporting their choices to lead the club this next year. We have accomplished much these past 12 months. I'd like to recap the most significant accomplishments and to thank some of the key players. For educational & public outreach we held about 30 star parties, served an estimated 7,000 people, distributed approximately $31,000 of donated materials, CDs and magazines, and involved close to 80 of our members. For our facility at Haystack, we completed the supporting roof structure and are ready for a new roof cover, erected a tool shed, cleaned and inventoried all resources in the glass room, started work on improving the library, completed the 20" compound reflector, installed a new general-purpose equatorial mount, and installed a computer network with five newer computers. We have also improved our good relationship with our landlord, and this past year Joseph Salah, Director at Haystack, granted us permission to expand our mosquito abatement program, installed, at their expense, connectivity to their network for always-on highspeed internet access, and provided us with access to radio astronomy gear. We have just received word from our Springfield Telescope Maker brethren that ATMoB now has access to their site, and for those that seek training, the 13" Schuppman. For these accomplishments we all owe a great amount of thanks to each other. Each and every one of us is both responsible and deserves credit. There are a few individuals that have stood out though, and I'd like to take the remainder of this space to recognize Dave Prowten, John Reed, Paul Cicchetti, Virginia Renehan, Eileen Myers, Gary Jacobson, Shilpa Lawande, Mike Hill, Paul Valleli, Gary Walker, Lew Gramer, Brewster LaMacchia, Marsha Bowman, Anna Hillier, Dave Siegrist, Ed Los, John Blomquist, Bruce Gerhard, Brian Maerz. I'd also like to recognize Anne Gorczica, Doug Harrison and Mike Poirier from MIT/Haystack. I'll continue to be an active member of the Executive Board, and to strive to make this club the best there is. Thank you, and clear skies to all, Bruce

This Month's Meeting...
Thursday, June 9th , 2005 at 8:00 PM Phillips Auditorium Harvard-Smithsonian Center for Astrophysics
Parking at CfA is allowed for duration of meeting

THIS MONTH'S SPEAKER will be TODD GROSS, TV7 News Chief Meteorologist & Amateur Astronomer. The title of Todd's talk will be "The Weather, how it affects our observing and imaging." Todd first became interested in astronomy at age 5. He had a "moonscope", planetarium, and other goodies which he forced his 4 and 5 year old friends to play with. He built his own 8" reflector as a teenager, and became an eclipse chaser, having witnessed 6 total eclipses. After becoming chief meteorologist at Channel 7 in 2002, he wound down some of his astro-mania but continues to share his enthusiasm for the skies with the public during his weather segments today. A native of New York City, he graduated from the State University of New York in Albany with a Bachelor of Science degree in atmospheric sciences. Todd has assigned us a bit of homework in order that we get the most from his talk. He invites all of us to read his article, published in Sky & Telescope in January 2000. S&T has granted us permission to post this article on our website for a limited time. This article is for ATMoB members only. Please respect their generosity and do not redistribute the article. Feel free to join together for a pre-meeting dinner at 5:45 PM (seating at 6:00 PM) at the Changsho Restaurant located at 1712 Mass Ave. in our fair city, Cambridge.


May Meeting Minutes. . .
The May meeting of the ATM's of Boston featured Bob Naeye of Sky and Telescope. Bob's topic was the search for extra-solar planets, and the acceleration of their discoveries. Bob first described the problem of finding the extra-solar planets, given their proximity to stars, and the low intensity of light reflected off them. Astronomers therefore use a variety of means to discover them, other than visual detection. Those means include: · astrometry - Early on most research was in this area, looking for the motion of the stars as the mass of planet rotated around it. There were many claims of discovering exoplanets, but to date, none have been confirmed based on astrometry. · variations in pulsars ­ by observing very small variations in the emissions of pulsars, as exoplanets orbit them. An early discovery was made in this way, but none since. · radial velocity (wobble) ­ As the planet-star system orbit about each other, the light from the star shifts slightly in frequency (Doppler effect) depending on whether it coming toward us, or moving away. This method can find massive planets, but has difficulty with smaller ones. It also can only find the minimum mass of the planet, but with no information about the inclination of the planets orbit, its actual mass is unknown. Several planets have been found in this way. · transit method ­ similar to eclipsing variables, a planet transiting in front of the star will reduce the light traveling to us. This is an area where amateurs can contribute, and we have heard from our own Gary Walker as he uses this method. · direct imaging ­ although difficult, effort is being made to image close brown dwarfs to discover if there are companion planets. To date there have been over 160 exoplanets discovered. The business meeting followed with standard reports from the club officers and committees · Clubhouse report: much progress has been made in shoring up the roof, readying it for a new surface. New stairs were built in the basement, and the high speed internet work has mostly been completed. Many folks have contributed long hours to make the clubhouse a resource for all of us. · June 11th is the club picnic, and we have invited the South Shore group to join us. · Al Takeda showed pictures from Astronomy Day at Dexter. A good time was had by all. · Mario reported on the lack of progress on the Dark Sky bill. He also updated folks on the eclipse trip to Egypt. Folks interested in joining them should contact Mario. · Paul Valelli reported on progress at Stellafane in building the pole barn. Donations would be much appreciated. Also, access to the observing field is now available to ATMoB'ers. Interested folks should contact Paul or Bruce for the details.

· The nominating committee reported on the slate of officers for the upcoming year. Bruce Berger has elected to invest more time in his job search, and will not be running for president. Those nominated include: President Bernie Volz Vice Pres. Virginia Renehan Secretary Mike Hill Treasurer Gary Jacobson Membership Dan Winchel At Large Dave Prowten, Bruce Tinkler · Peter Bealo showed a film from the recent Titan rocket launch, and Chuck Evans showed images from his recent visit to Kitt Peak. The meeting was adjourned to a time of fellowship among the membership. - Dave Siegrist -

Annual Meeting Announcement
The Annual Meeting of the Amateur Telescope Makers of Boston, Inc. will be June 9, 2005. The election of the 20052006 Executive Board will take place at the meeting.

Clubhouse Report
Over the past five weeks seventeen members contributed 42 member days for clubhouse projects (April 23 through May 28, '05). With the end of winter, the snow fence and posts were removed and stored; mowing, trimming, and chipping commenced; propane was purchased and mosquito magnets set up, repaired, and are now running. The roof support bridge system in that attic was completed and hurricane ties installed. The old basement stairs were removed, new stairs were built and installed in one day; a new railing was installed the next day. A new attic window was installed on the west end. A second bat house was installed next to the first bat house, and both are now occupied. The attic refuse was partially removed and the far barn cleared to receive roofing supplies. Internet work continued and first light was reported. Picnic planning and the 2005/2006 budget planning proceeded. Sky and Telescope sorting continued with excess issues set aside for star parties. Thanks to the following ATM's: Dick Koolish, Carl Goedecke, Bruce Berger, Phil Rounseville, Brian Leceau, Larry Swezey, Virginia Renehan; with special thanks to Paul Cicchetti, Bruce Gerhard, Brian Maerz, Eileen Myers, Anna Hillier, Steve Clougherty, Art Swedlow, Dave Prowten, John Blomquist, and Jonh Reed.

Club History
The Historical Committee met on Saturday, May 21st at 10:00 a.m. at the Clubhouse to discuss the editing of the club history. Anna Hillier and Eileen Myers went over the articles, discussed photos and the possibility of having the club history published as a soft cover book. Serendipitously, at 2:00 p.m. Karen Reardon arrived at the clubhouse ­ her first visit ­ and agreed to help. Karen is a professional technical writer with extensive experience publishing this type of work. Karen is the wife of new member Yuval Gonen, who came to the clubhouse to lend a hand with the clubhouse computer network. We are going to have a deadline of August or September 2005. We hope to add some more content and photographs, formatting the history so that it looks pleasing to the eye and also a joy to read. -Anna Hillier and Eileen Myers-
