Coincidentally, yesterday, I picked up the National Geographic Magazine for August 1974 at the local resale shop, for $.10.
One of the lead articles was coverage of the Comet Kohoutek viewing from March 1973. Here's the Wiki report on that:

An hour ago, I tuned into the current live report of the landing of Rosetta... basic info here:

Nothing more to be said, except that I remember the event from 41 years ago, trying to see the comet tail, but being disappointed because of the weather.
Deja Vu... and a moment of awe.
