The Observers Notebook -Tycho Tracker Software
14/02/2026 Duración: 01h08minEpisode 230 In this episode of The Observers Notebook, host Tim Robertson talks with Daniel Parrott, the creator of Tycho Tracker — a powerful software tool that brings professional-level asteroid detection and measurement to amateur astronomers around the world. Daniel shares the story behind Tycho’s development, explains how synthetic tracking helps detect faint moving objects, and offers practical tips for observers submitting data to the Minor Planet Center. They discuss GPU, (graphics processing unit) acceleration, photometric tools, common beginner mistakes, and how community science is reshaping asteroid discovery. Tycho now also supports lightcurve generation, rotation period analysis, and variable-star photometry, expanding its utility far beyond asteroid hunting. Whether you’re a seasoned asteroid hunter or just curious about how software can turn your backyard telescope into a discovery machine, this episode is packed with insights and inspiration.

The Observers Notebook - Astronomy Outreach with Pranvera Hyseni
15/01/2026 Duración: 01h10minEpisode 227 In this episode of the Observers Notebook podcast, host Tim Robertson talks to Pranvera Hyseni — founder of Astronomy Outreach of Kosovo, driving force behind Kosovo’s first National Observatory and Planetarium, and one of the most influential young voices in global astronomy education. Pranvera shares her remarkable journey from discovering the night sky in post-war Kosovo to becoming a worldwide leader in science outreach, earning international recognition and even having asteroid 45687 Pranverahyseni named in her honor. We explore how she built Astronomy Outreach of Kosovo (AOK) from a one-person dream into a national movement reaching tens of thousands of students, teachers, and families each year. She discusses the challenges of grassroots outreach, the role of female leadership in STEM, building a planetarium from the ground up, and how amateur astronomers everywhere can empower their own communities.

The Observers Notebook- Comets of 2026
01/01/2026 Duración: 01h13minEpisode 226 In this episode, we’re turning our eyes toward some of the most dynamic travelers in our solar system — comets — and looking ahead to what promises to be an exciting year in the night sky: 2026. Each year brings a new lineup of these icy visitors, and with them, the chance for both amateur and professional observers to witness spectacular changes as they approach the Sun and develop tails of gas and dust. But which comets will stand out in 2026? Which ones might become visible to the naked eye — and which could surprise us? To help answer those questions, I’m joined by Carl Hergenrother, Coordinator of the ALPO Comets Section and a veteran comet discoverer himself — yes, he even has one named after him, Comet 168P/Hergenrother. Carl has spent decades studying, imaging, and analyzing comets from both professional observatories and backyard telescopes. Together, we’ll explore which comets are expected to light up the sky in 2026, how to observe them, and what role amateur astronomers can play in mo

The Observers Notebook- Sketch or Science? The true value of Lunar Drawings
01/11/2025 Duración: 54minEpisode 222 In this episode of The Observers Notebook Podcast, host Tim Robertson sits down with Alberto Anunziato, an ALPO Lunar Observer from Argentina.

The Observers Notebook- Titan's Transit of Saturn
10/09/2025 Duración: 22minEpisode 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.
