While everyone is watching the total eclipse, bright sunlight can be seen behind the crowd.
In an opening scene, the camera shows Taggart from behind as he is lecturing a group of children and his legs are visible all the way down to his feet. When the camera view switches to show him from the front, there is a bench immediately behind him and he sits down on it. The bench was missing from the previous view or it would have blocked the view of his legs.
Taggart's theory that exotic mesons created by solar flares causing spontaneous human combustion is flawed because mesons are very unstable particles that only exist for a few milliseconds after being formed, so they would never reach Earth, since it takes light roughly 8.3 minutes to reach Earth, the mesons would decay long before they got here.
Sheriff Carter says to Henry, "you and I are going to be living with the memory of a timeline that's gone."
At the end of season 1, "Once in a Lifetime," Sheriff Carter stopped Henry from creating that other timeline. Since Sheriff Carter stopped Henry from creating that other timeline, Henry would never have gone through it, hence this Henry would have no memory of the other timeline.
What is overlooked, is that there are three timelines involved. The original timeline, where Kim died and Henry didn't come from the future. The altered timeline we see in Once in a Lifetime (2006) where Henry came from the future and saved Kim. And the final timeline, where Carter comes from the future to prevent Henry from saving Kim. Henry has the memories from the original timeline. Carter has the memories of the "Once in a Lifetime" timeline. They both indeed have memory of a timeline that's gone.

Everyone puts on high tech eclipse glasses to view the sun before totality. At totality, everyone should be taking their glasses off to be able to see the sun's corona (aka Taggart's Firebird).
