NASA + Lunar Eclipse = A Super(moon) Match Made in Metrics Heaven

Sep 28, 2015

NASA’s reach over the last 24 hours eclipsed that of the regulars typically seen in government digital metrics. But, all agencies can drive the conversation and accomplish a similar feat with a good content strategy.

A screen capture from shows that 274,629 people visited U.S. governnment websites at 10:19 pm on September 27, 2015 during the Super Blood Moon lunar eclipse.

NASA defines a supermoon, which appears approximately 14 percent larger in diameter due to its proximity to the Earth, as: a full or new moon that falls closest to the fall equinox, and is at its closest approach to the Earth.

Sunday’s supermoon eclipse, visible to North and South America, Europe, Africa, and parts of Asia and the eastern Pacific, lasted an hour and 12 minutes. It is the first time since 1982 that both a supermoon and a total lunar eclipse have made an appearance together.

If you weren’t able to make one of the eclipse parties happening in many cities, or were experiencing heavy cloud cover, NASA Television live-streamed the event from their Marshall Space Flight Center in Huntsville, Alabama. Hosts conducted many live and pre-recorded interviews about last night’s supermoon, lunar and solar eclipses, and interesting facts about Earth and the moon. They referred to the hashtag #AskNASA to answer questions from the public across various social media channels, from 8 pm until midnight. ICYMI, watch the broadcast on NASA&’s Ustream channel.

While the next supermoon will be October 27, 2015, the next supermoon eclipse won’t happen until the year 2033 (this rarity has only happened five times since 1900!).

This morning, the hashtag was still the Top Trend in Facebook’s Science and Technology ticker. NASA ran a #SuperBloodMoon Photo Contest on their Facebook page, which received over 1,500 submissions yesterday from all around the world within the first 2 hours. The best shots are being featured in their gallery on Facebook; voting begins at 3 pm Eastern today. This is a great example of harnessing user-generated content to keep the conversation going.

At 8:45 pm, about 20 minutes before the first partial eclipse began,, which updates every minute, reported 157,796 people were visiting U.S. government websites. NASA had 13 of the Top 20 and held the first 7 spots. As the night progressed, so did the numbers.

9:07 pm: start of first partial eclipse

  • 186,370 visitors; NASA had 12 of top 20; first 7 spots

9:40 pm: during first partial eclipse

  • 224,228 visitors; NASA had 14 of top 20; first 9 spots

10:11 pm, start of full eclipse and “blood moon” phase

  • 240,974 visitors; NASA had 17 of top 20; first 9 spots

The number of people visiting government websites—particularly NASA websites—peaked around 10:19 pm, about 8 minutes into the full blood moon eclipse, with 274,629 visitors. NASA still had 17 of the Top 20 pages, but had taken over the first 11 spots. While the number of visitors dropped dramatically only a half hour later (206,371), NASA still held the reigns on the Top 20 list with 16 spots, including the first 9.

As this rare celestial event began to come to a close at 11:23 pm with the start of the 2nd partial eclipse, NASA held on to 14 of the Top 20 as 126,642 people visited U.S. government websites. When it ended at 12:27 am, 66,871 people were still perusing government websites, and NASA still had the attention of over 50 percent of folks visiting the Top 20 pages with 11 spots in the list, including the first 6.

What’s next?

During the broadcast of last night’s supermoon eclipse on NASA TV, solar scientist Mitzi Adams of NASA’s Marshall Space Flight Center shared her interview with a Scientist Emeritus of NASA’s Goddard Space Flight Center that had been pre-recorded for the event on Friday. Astrophysicist, author, and eclipse expert, Dr. Fred Espenak, spoke about one of the upcoming eclipse events, the 2017 total solar eclipse.

Also known as America’s Eclipse and the Great American Eclipse because it runs exclusively through the United States, this too is a rare eclipse and has been predicted to take place on August 21, 2017. Those lucky enough to be in the Path of Totality (the path that the moon’s shadow takes as it crosses the United States), from Oregon in the northwest to the Carolinas in the southeast, will be able to see all phases of this kind of eclipse which hasn’t happened since 1979.
