ISS pass · Wednesday 7 October 2026
The verdict for Guyana
It was in reach of the naked eye from Georgetown, in twilight, at 6:01 pm GYT, not an hour later.
It rose above 10° at about 6:00 pm GYT, peaked at 18:01:20 GYT 17° up, low in the south-west, and dropped below 10° at about 6:04 pm GYT, at about magnitude 1.2.

What was said, and what we found
7 Oct, 18:59:07
Heavens-Above’s pass list for Georgetown with its first GMT-4 time zone, “(GMT-4:00) Canada (Atlantic), Bermuda, Greenland (Thule)”, read on 7 October 2026; on 14 October the same setting still printed its clock as UTC -03:00. “ISS - Visible passes, Georgetown”, published 7 October 2026. Read the source, fetched 7 October 2026.
The time is an hour late. Guyana keeps UTC-4 all year, with no daylight saving. The page was set to Atlantic Time, which keeps daylight saving (UTC-3 in October), so its 18:59:07 is one hour after the pass really climbed past 10° at about 6:00 pm GYT; anyone who went out at 18:59 missed it.

The details
Guyana is on UTC-4 all year and never changes its clocks. Apps and websites that ask for a time zone often list Atlantic Time first; it moves to UTC-3 for daylight saving from March to November, and every time it shows is then an hour late for Guyana.
In a pass list, choose a zone named for Guyana, or any fixed UTC-4 with no daylight saving.
Find it
At its highest from Georgetown, 18:01:20 GYT: face the south-west and look about one and a half fists up from the horizon (17°).
At arm’s length a fist covers about 10°, a hand-span about 25°.
How to watch
The ISS looks like a bright, steady star moving across the sky in a few minutes, with no blinking lights.
It is only seen for an hour or two after sunset or before sunrise, when it is in sunlight and your sky is dark.

For a class
Work out UTC from a Guyana time, then the time in Atlantic daylight time, to see how an hour slips in.
Ask students to watch a pass and time how long it stays above the trees.
