Interstellar phenomena forecast is a term used to describe passing pulsars.
In 2376, Federation space station Deep Space 9 predicted that a pulsar would pass close to the MIDAS array. By firing a tachyon beam at the pulsar, Pathfinder Project was able to create a micro-wormhole through which they made contact with USS Voyager 30,000 light years away in the Delta Quadrant for a brief period.

- Interestingly, this is the only mention of Deep Space 9 since Star Trek: Deep Space Nine ended.
