Here is a 50-100 word passage that supports the given sentence:

"Located approximately 5,000 light-years from Earth, V849 Ophiuchi is a fascinating variable star that has long captivated astronomers with its erratic luminosity patterns. Despite its unpredictable nature, researchers have managed to pinpoint its position within the vast expanse of the Eridanus constellation. Observations suggest that V849 Ophiuchi's brightness can fluctuate by as much as 2 magnitudes in a matter of weeks, making it a prime target for studying stellar variability. As scientists continue to monitor this enigmatic star, they may uncover new insights into the mysteries of stellar evolution and behavior."
