Here you'll find some of the best eclipse websites available, as judged by members of the AAS Solar Eclipse Task Force. To avoid overwhelming you with too much information, we've intentionally weighted our listings toward resources that are relatively new, up to date, and/or especially relevant to the August 21, 2017, solar eclipse across America. We've also considered quality, of course; if a website is listed here, we think it's of high quality. If it's not listed here, that doesn't mean it's not of high quality — it just means we can't list everything. If you have, or know of, a resource that you think belongs here, please contact us; we can't guarantee that we'll add the item to our website, but we will consider it.
