A total {{w|solar eclipse}} occurred {{w|Solar eclipse of April 8, 2024|on April 8, 2024}} in North America, ten days before this comic. This comic comments on the fact that most solar eclipses happen on territories not easily reachable by humans, places with weather conditions that make viewing the eclipse less appealing, like cloudy skies (mentioned previously in [[2915: Eclipse Clouds]] and [[2917: Types of Eclipse Photo]]), fog, or tornadoes (also a [[:Category:Tornadoes|recurring subject]] on xkcd), or areas that experience only a short period of totality.

{| class="wikitable"
|-
! Zone label !! Geography !! Suitability for observation
|-
| Zone where totality lasts 1-2 seconds || Land || No stated issues for visiting, but rendered all too brief an experience for astronomical reasons.
|-
| Bay of shifting ice || Water (part frozen) || Open water might make this location accessible by boated observers. Solid ice ''might'' grant observers ready access by skidoo, ski and/or skid-plane. Shifting ice causes problems for all these modes of access.
|-
| Shipwreck cove || Water/Coast || The name describes the likely impediment to any boat access.
|-
| Desert so harsh they train Mars astronauts there || Land (peninsula) || Implied inhospitable, and probably a lack of any normal transport/accommodation infrastructure.
|-
| Sea of rocky crags and maelstroms || Water (straits) || Yet more risk of nautical hazards, including {{w|Whirlpool|strong rotating currents}}. Possibly a nod to Scylla and Charbydis from The Odyssey.
|-
| [State department travel advisory] || Island || Unknown risk, but probably involves some form of political instability, war, or major health hazard that makes unnecessary visits highly inadvisable. May also be a result of adverse weather effects. Or perhaps all of these at the same time.
|-
| Isle of perpetual fog || Island (inc. littoral zones?) || Meteorologically unfortunate (ground visibility; ''may'' not fully obscure the skyward view).
|-
| Nice, scenic, accessible area (6 square miles, 40,000,000 visitors expected) || Land || Apparently ideal in all respects. Except for the crowds. (Would entail up to three people for every square metre, even before accounting for the existing population and obstructions, as well as a high probability of {{what if|8|travel congestion}}.)
|-
| Tornado capital of the world || Land || Meteorologically unfortunate (frequent disruptive wind vortices, and cloud cover likely).
|-
| Area where the eclipse will be low in the sky, behind the tornadoes || Land || Astronomically disadvantageous, with added complications from the neighbouring weather system.

The title text mentions the {{w|Solar eclipse of February 28, 2063|solar eclipse of February 2063}}, and claims it will only be visible from the Arctic, though in fact this annular eclipse will traverse through the Indian Ocean. The eclipse in the comic would supposedly happen when the {{w|Sun}} would be below the horizon, which is a contradiction in terms, since an eclipse is only an eclipse from the standpoint of the viewer — it is equivalent to saying that the eclipse is not visible from that location, but is visible from a location over the horizon, at a point that is at the other end of a direct straight line {{w|Chord (geometry)|through the Earth}} that is directed 'down' towards the unrisen Sun and Moon. It then jokingly suggests that a giant chasm could open up between the location being considered and the location from where it would be visible, allowing people to view it. If this did happen, the chasm itself would likely eclipse the eclipse as a spectacle. In most cases, it would also likely cause severely detrimental effects (for example, magma eruptions, tsunamis, etc.), and would therefore not be considered 'lucky' by most people, despite the small and short-term benefit of being able to view an eclipse from a previously unsuitable location.

'''Note'''

The {{w|Novaya Zemlya effect}} can make it possible to observe a solar eclipse when the Sun is below the horizon at the poles during certain weather conditions. Also called a "polar mirage", the effect is when an atmospheric inversion ducts sunlight along the surface of the Earth for distances up to 250 miles (400 km), which would make the Sun appear 5° higher in the sky than it actually is. This appears to be the rare situation where [[Randall]] was unaware of an obscure scientific phenomenon that would contribute to a joke.

172.69.59.8:

The bot didn't upload the most recent comic so I tried to do it myself, but I think I screwed it up :([[User:Szeth Pancakes|Szeth Pancakes]] ([[User talk:Szeth Pancakes|talk]]) 18:31, 23 June 2023 (UTC)

I think the term "bird strikes" should be interpreted as a plural noun, given the two Xs on the map. Something like "After bird strikes, judge ... overturned but rights and lands safely" [[Special:Contributions/172.69.59.8|172.69.59.8]] 20:30, 23 June 2023 (UTC)
