We present the results from a new optical/UV/X-ray monitoring campaign of the luminous Seyfert galaxy Fairall 9 using the Swift satellite. Using the UV-Optical Telescope on Swift, we find correlated optical/UV variability on all timescales ranging from the sampling time (4?days) to the length of the campaign (2.5?months). In one noteworthy event, the UW2-band flux dips by 20% in four?days, and then recovers equally quickly; this event is not seen in either the optical or the X-ray bands. We argue that this event provides further evidence that a significant fraction of the UV-emission must be driven by irradiation/reprocessing of emission from the central disk. We also use an archival XMM-Newton observation to examine shorter timescale UV/X-ray variability. We find very rapid (10?ks) UV flares of small amplitude. We show that, unless this emission is non-thermal, we must be seeing the Wien tail from a compact (3 light hours), hot (T 8 × 104?K) region. The possible association with X- ray microflares suggests that we may be seeing the UV signatures of direct X-ray flare heating of the innermost disk.
