Detection of a flare in the X-ray emission from NGC 5506.
Abstract
X-ray observations of the type 2 Seyfert galaxy NGC 5506 over a 4-yr period are reported. Although the light curve shows no indication of long-term variability, a significant flare in the X-ray emission lasting about 3 days is observed. There is now evidence for X-ray variability on a time scale of a few days or less for most classes of active galaxy.
