A [[solar eclipse]] occurs when the [[Moon]] passes between [[Earth]] and the [[Sun]], thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A partial solar eclipse occurs in the polar regions of the Earth when the center of the Moon's shadow misses the Earth.<ref>{{Cite web|url=https://www.timeanddate.com/eclipse/solar-eclipse.html|title=What Is a Solar Eclipse?|website=www.timeanddate.com|language=en|access-date=2020-04-24}}</ref>

A partial eclipse was visible for parts of Northern [[Russian Empire|Russia]], [[Territory of Alaska|Alaska]], Western [[Canada]], and the [[Pacific Northwest]].

== Eclipse season ==
{{See also|Eclipse cycle}}
This eclipse is part of an [[eclipse season]], a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) later; thus two full eclipse seasons always occur each year. Either two or three eclipses happen each eclipse season. In the sequence below, each eclipse is separated by a [[fortnight]]. The first and last eclipse in this sequence is separated by one [[month#Synodic_month|synodic month]].
