How Much Declination Do Stars Need for a Luck City at Latitude 35°?

AI Thread Summary
For a city at latitude 35°, the concept of a "luck city" is tied to the length of the visible arc of a star's path. The discussion centers on determining the necessary declination of a star for optimal visibility in this location. The focus is on achieving the longest possible arc, rather than on specific stars. The exact declination needed for a star to qualify as part of a luck city remains unclear. Overall, the emphasis is on declination rather than the identity of the star itself.

People in the past thought that a city which the length of the visible arc of a star's path in that city is longer, that city is the luck city; Now, for a city with a latitude of 35° how much should be the star's declination to be the luck city?

Longer than what?
Which star?
Is that homework?

longer means the longest arc available. and the star is not important, just the declination is the thing.
 

Thread 'How feasible is home radio astronomy?'

Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...

Thread '3I/ATLAS, Interstellar Comet'

3I/ATLAS, also known as C/2025 N1 (ATLAS) and formerly designated as A11pl3Z, is an iinterstellar comet. It was discovered by the Asteroid Terrestrial-impact Last Alert System (ATLAS) station at Río Hurtado, Chile on 1 July 2025. Note: it was mentioned (as A11pl3Z) by DaveE in a new member's introductory thread. https://www.physicsforums.com/threads/brian-cox-lead-me-here.1081670/post-7274146 https://earthsky.org/space/new-interstellar-object-candidate-heading-toward-the-sun-a11pl3z/ One...
