The Moon and the stars — November 2028
Lunar occultations of stars to magnitude 9.5, computed for your location
Every night the Moon slides in front of stars. A star doesn't fade behind it — it switches off, then switches back on at the other edge, often an hour later. Pick your place and what you observe with; the list keeps what you can realistically see.
26 occultations you can see from New Delhi with small telescope (80 mm) this month, on 15 nights · 1126 in all from there
Times in IST. A night runs from noon to noon, so an event at 01:30 stays with the evening before. On each Moon, the numbered marks show where on the limb each star disappears or reappears.

Reading the list
The Moons are drawn from LRO LOLA topography (a 40 KB relief map), lit by the Sun as it is at that moment and turned to the Moon's real libration: north up, east to the left. A dark-limb event — the star vanishing into, or popping out of, the unlit edge of the Moon — is easy to see. At the bright limb only bright stars show against the glare. PA is where on the limb it happens, measured from north through east; the cusp angle is the distance from the nearest horn of the crescent. graze marks a star passing within 3″ of the edge from your place: a few kilometres from a graze line, where it may blink several times behind mountains.
| Instrument | dark limb | bright limb |
|---|---|---|
| Naked eye | V ≤ 3.0 | V ≤ 1.0 |
| Binoculars | V ≤ 6.5 | V ≤ 3.5 |
| Small telescope (80 mm) | V ≤ 8.5 | V ≤ 5.5 |
| Telescope (200 mm) | V ≤ 9.5 | V ≤ 7.0 |
Those limits are rules of thumb: the dark-limb limit drops by 2.5 magnitudes × (lit fraction − 0.4) in moonglare and by 1 in twilight; events with the Moon under 5° are left out, and daylight events except for the brightest stars. Stars are from Gaia DR3 to G 9.5, with Hipparcos-2 for the brightest and the Yale Bright Star Catalogue for names; the Moon is from the JPL DE431 ephemeris. Times are for the Moon's mean limb, ±2 s — mountains at the edge can move a contact by a few seconds, and much more near a graze.
