Why the seat matters

Bright comets live in the twilight wedge, ten to twenty degrees up, in the same part of the sky as every horizon obstruction and every layer of haze. La Palma stacks the deck: 2,400 m of altitude puts you above the trade-wind inversion, so you look down on the cloud deck instead of through it. The catch is that the island itself is a two-kilometre wall, and which side of it you are on decides whether you see anything.

Dataset note. REHEARSAL SCENARIO. No bright naked-eye comet is currently predicted. This show exists to let you practise the vantage problem a great comet creates; the comet itself is simulated, not forecast.

Every seat, ranked

Seat fit is the simulator’s own score — darkness, open horizon, historical clear-sky odds, altitude and reachability, weighted for what this show cares about. It ranks seats against each other; it is not a forecast for any night. Tap a seat for the full card.

    Roque de los Muchachos

    Front row · 28.754°N 17.885°W 84 Bortle1Clear88%Blocked10%

    Seat fit 84/100 — Front-of-house seat for this show.

    Above the trade-wind inversion, on top of the cloud, at the best-protected dark sky in Europe. Ninety-five minutes of hairpins and the road can shut without notice.

    Seat fit 77/100 — Strong seat. Weakest link: altitude.

    A viewpoint built for exactly this, with a six-percent western horizon over black lava. Half the drive of the Roque for most of the sky.

    Seat fit 70/100 — Strong seat. Weakest link: altitude.

    Shelter, toilets and pines — and the pines are the problem. A fifth of the sky is Canary pine exactly where a low comet lives.

    Seat fit 70/100 — Strong seat. Weakest link: altitude.

    Six hundred metres straight above the sea with the Aridane valley below and nothing to the west but ocean. A cafe, a railing, and eight percent obstruction.

    Seat fit 66/100 — Strong seat. Weakest link: altitude.

    A black-sand promenade with a four-percent sea horizon and a bar behind you. Streetlights sit right in the sightline, which for a faint tail is fatal.

    Seat fit 63/100 — Strong seat. Weakest link: open sky.

    Inside the Caldera de Taburiente with walls on three sides. Astonishing by day; for a low object it is a seat in a well.

    Seat fit 48/100 — Workable compromise. Altitude is what you are paying.

    The town is on the east coast and the comet is in the west, behind two thousand metres of island. Convenient and, for this show, nearly useless.

What is actually happening

Inside roughly three astronomical units the Sun's heat sublimates a comet's ices directly to gas, dragging dust with it. Two tails result and they point in different directions: the ion tail is blown straight anti-sunward by the solar wind at 400 km/s and glows blue from ionised carbon monoxide, while the heavier dust tail lags along the orbit and curves, scattering sunlight yellow-white. A great comet is a naked-eye object low in twilight, not a telescope target.

Other shows

Front Row is a planning simulator on a curated dataset. Every place and coordinate is real; elevation, Bortle class, horizon obstruction and cloud odds are researched estimates for the site and season — climatology and site character, not a forecast. Background skies are rendered by the simulator, not photographed. Verify real conditions and access with an authoritative local source before you travel.
