The upcoming solar eclipse is generating excitement amongst space enthusiasts and sky gazers alike. With the path of totality stretching from southwest to northeast, experts are advising eclipse chasers to carefully select their viewing locations for the best experience.

According to Dr. Tyler Nordgren, an astronomer and author, the duration of totality depends on your proximity to the centerline of the path. The closer you are to this centerline, the longer the totality will last. Dr. Nordgren explains that it is akin to two circles overlapping, with the larger moon obscuring the smaller sun. At the edge of this path, the sun is only completely covered for a fleeting moment. However, standing on the centerline grants the luxury of a longer duration of totality as the circular shadow takes more time to pass over.

Nordgren cautions against being right on the edge of the path of totality, as this can be risky. The edges of the moon's shadow are a projection of its terrain, which brings the possibility of craters or valleys obstructing the view. This is not typically an issue in remote areas, where most eclipse chasers venture. However, some cities, such as the CBD of San Antonio and Austin's airport, will miss out on totality as they fall near the edge.

While being on the centerline is ideal, Nordgren assures that there is no need to obsess over it. As the distance from the centerline increases, the difference in totality duration becomes less significant. As crowds flock to locations directly on the centerline, choosing a spot just shy of it can still yield an incredible experience. Sacrificing a few seconds of totality won't dampen the awe-inspiring nature of witnessing a solar eclipse.

Olivier Hernandez, Director of the Rio Tinto Alcan Planétarium, adds that regardless of the duration, totality always feels like it lasts eight seconds. So, even if you miss a few seconds, the overall experience remains breathtaking.

Looking back at the last total solar eclipse in 2017, totality lasted around 2 minutes and 40 seconds, which is a typical duration. Nordgren, who prefers not to be at the exact centerline, advises eclipse chasers to prioritize being in the path of totality and to ensure clear weather conditions. In the end, it is the awe-inspiring moment of witnessing the moon's shadow traversing the sun that truly matters.

As the solar eclipse draws near, enthusiasts are eagerly finalizing their viewing plans. Remember to choose a location along the path of totality, avoid the risky edges, and be prepared for an unforgettable experience.
