IS IT MOVING OR FLASHING?

A point of light that drifts steadily across the sky in a minute or two — not twinkling, no flashing lights — is a satellite (often the ISS or a Starlink train). A blinking light moving in a straight line is an aircraft. The objects above don't move noticeably over a few minutes.

The list is ordered brightest-first and updates through the night. A planet shines with a steady light; a star twinkles; a point that drifts across the sky in a minute or two is a satellite. Best viewing is once the sky is fully dark — check our stargazing conditions for San Juan.
