The Observers Notebook- Observing Mars 2025

Episode 207

In this episode of the Observers Notebook podcast, host Tim Robertson talks to Sam Deen, as a child, he began searching for exoplanets, but soon he was not satisfied with simply clicking on the offered images. He wanted more, to use the available data for his own scientific research. After a year, he left university studies to devote all his time to astronomy. He finds lost asteroids, comets or identifies small bodies of the Solar System overlooked by scientists, starting from new near-Earth asteroids, unknown moons of Jupiter, and ending with extremely distant trans-Neptunian objects. Self-taught, who has developed into a unique expert, the detective of the astronomical archives.

We discuss Sam’s life and experiences in Discovery of objects and contact information.

The Observers Notebook- Sam Deen Celestial Hunter

Episode 211


In this episode of the Observers Notebook podcast, host Tim Robertson talks to the ALPO member Jim Tomney on the upcoming Virtual ALPO Conference. 

The dates will be Friday and Saturday, July 25/26, 2025. The conference will also be Live Streamed on the ALPO YouTube channel.

As a "virtual" event, this year's ALPO conference will NOT be an in-person event. 
This way, you can participate from the comfort of your own home or office.

The conference times for both days will be from 10 a.m. to 2 p.m. Pacific Time (1 p.m. to 5 p.m. Eastern Time) and allow for seven paper presentation sessions each day with short breaks on both days. All presentations be limited to approximately 25 minutes each with a few minutes left for audience questions.

The schedule of presentations will be posted about one week prior to the event.

The ALPO board of directors meeting will be held on Friday, July 25 at 4 p.m. PT (7 p.m. ET). 

The ALPO Conference is free and open to anyone to attend; however, all presenters must be current members of the ALPO. Digital memberships start at only $22 a year. To join online, go to https://www.alpo-astronomy.org/ALPO/Home/Join.

Following a break after the last paper presentation on Saturday afternoon, July 26, will be presentation of the annual Walter Haas Observer Award. 

This will be followed by our keynote speaker at 4 pm. PT (7 p.m. ET). With the award presentation and keynote speech usually occurring at the traditional Saturday evening 
dinner, we suggest that you enjoy your own meal during these last two conference events.
Door prizes will be awarded following the Keynote address. No purchase necessary.

The only hardware required along with your computer are a webcam and microphone. If you will be using a laptop computer, both are already built into your system. 

An online chat feature will allow type-in text comments for questions once the conference gets underway.
All presenters must already have ZOOM installed on their computer prior to the conference dates. 

ZOOM is free and available at https://zoom.us/

The ZOOM links will be e-mailed out on Thursday, July 24. Send a request to cometman@cometman.net

There will be a separate ZOOM meeting set up for each day. 
The ZOOM virtual (online) meeting room will open 15 minutes prior to the beginning of each day’s activities.

Upon logging into ZOOM you will be placed into a ‘waiting room’ until the meeting begins, and your microphone will be muted automatically.

Those individuals wishing to present a paper should submit their request to Tim Robertson at cometman@cometman.net no later than July 1st, along with a brief bio about themselves and a summary of their presentation. Microsoft PowerPoint is the preferred method of visual presentation along with an audio explanation.

The Observers Notebook- The Lunar Observer

Episode 219

In this episode of the Observers Notebook podcast, host Tim Robertson talks to Bob Lunsford about his process for observing and photographing the recent transits of Saturn’s moon Titan.

Titan’s Orbit and Motion:
•	Orbital period around Saturn: ~15.945 Earth days
•	Average distance from Saturn: ~1.22 million km
•	Orbital inclination: ~0.3° relative to Saturn’s equator (small, so Titan’s path is nearly aligned with Saturn’s rings).
•	Apparent size: ~0.8 arcseconds (tiny, only detectable as a “point” in most telescopes).
•	Shadow transits are possible only when Saturn’s rings are edge-on (every ~15 years).
•	September 20, 2025 — Start around 5:09 AM UTC (≈10:09 PM PDT); ends ~7:34 AM UTC (~12:34 AM PDT); Titan may also be visible near its shadow. 
•	After October 5–6, 2025, this spectacular phenomenon won’t happen again until 2038–2039.

Observers Notebook - New Coments in the sky!

Episode 222

In this episode of The Observers Notebook Podcast, host Tim Robertson sits down with Alberto Anunziato, an ALPO Lunar Observer from Argentina. Together, they explore the fascinating intersection between art and science in lunar observation — how detailed sketches made at the eyepiece can capture fleeting features of the Moon, aid in scientific study, and preserve the personal experience of observation.

Is sketching an artistic pastime or a scientific tool? Alberto shares his insights, techniques, and passion for visual recording of lunar phenomena, reminding us that even in the digital age, a sketch can reveal what a camera may miss.
