A new viral news story claims some cities just “lost” totality. A NASA scientist explains what’s going on.
If you ’ve made it here , chances are you are upset that your pre - decided " choice location within thesolar eclipse ’s course of totality " is not so prime anymore .
Recently , some word that the way of entirety suddenly " moved"has been induce headlines , and someeclipse chasersacross the commonwealth have start to worry that they might not witness sum anymore . But do n’t accent , we ’re here to aid — even better , NASA scientist are .
What the theory claims is that , due to newfound uncertainty around the sizing of the sun , the width of the betoken path of totality is actually a little off . New calculations really make it more or less minute than what it was before , which means that some cities and areas that were antecedently identify as being locate within the path of aggregate , are now actually justoutside of it . In short , multitude in those cities would n’t be able to see the moon completely blocking off the Lord’s Day on April 8 .

Do n’t change your travel plans just yet . It is n’t as big of a shift as it sounds like .
" Calculations that use a slimly larger radius for the sizing of the sun yield an eclipse path that is slightly narrower , " Dr. Michael Kirk , a research scientist in the Heliophysics Science Division at NASA ’s Goddard Space Flight Center , told Thrillist . " This difference would only affect cities on the very edge of the path of totality , where blanket prediction are difficult regardless — a few metropolis blocks one way or the other could mean 20 , 10 , or 0 bit of aggregate . "
to boot , the size of the sun is n’t the only component that could strike the path ’s predicted width and size . " Uncertainty in the Earth ’s rotation can also affect occultation predictions on this stratum , " explains Dr. Kirk . " Traveling towards the center of the itinerary of entireness — even a nautical mile or two — will quickly increase the duration of total that mass can see . "
What to Expect of the Solar Eclipse Outside the Path of Totality
Here’s the percentage of totality you’ll experience depending on where you are on April 8.
I cognize what you ’re really inquire , though . Does this mean that NASA ( and everyone else ! ) was untimely about the antecedently reportedpath of totality ? Well , kind of — but also , not really . anticipation and calculations of this kind always take into accounting a margin of error , so if you bet directly at the column inch measurement then sure as shooting , everyone ’s prediction is probably a small off .
" I would consort that given all of the precariousness , probably all single-valued function are at least a little wrong , " says Dr. Kirk . " NASA use all of the measurements from our fleet of Earth , sun and moon observations , but it ’s still not enough for a 100 % accurate mapping . "
What ’s the solution , then ? According to Dr. Kirk , staying away from the route ’s edge should be enough . " If you are right near the edge of totality , " he aver , " I personally would n’t count on the anticipation from us or anyone else . "
