We could accurately predict the shadow path and successfully observe anoccultation of a bright star by Chiron on 2022 December 15. The KottamiaAstronomical Observatory in Egypt did not detect the occultation by the solidbody, but we detected three extinction features in the light curve that hadsymmetrical counterparts with respect to the central time of the occultation.One of the features is broad and shallow, whereas the other two features aresharper with a maximum extinction of $\sim$25$\%$ at the achieved spatialresolution of 19 km per data point. From the Wise observatory in Israel, wedetected the occultation caused by the main body and several extinctionfeatures surrounding the body. When all the secondary features are plotted inthe sky plane we find that they can be caused by a broad $\sim$580 km disk withconcentrations at radii of 325 \pm 16 km and 423 \pm 11 km surrounding Chiron.At least one of these structures appears to be outside the Roche limit. Theecliptic coordinates of the pole of the disk are $\lambda$ = 151$^\circ~\pm$8$^\circ$ and $\beta$ = 18$^\circ~\pm$ 11$^\circ$, in agreement with previousresults. We also show our long-term photometry indicating that Chiron hadsuffered a brightness outburst of at least 0.6 mag between March and September2021 and that Chiron was still somewhat brighter at the occultation date thanat its nominal pre-outburst phase. The outermost extinction features might beconsistent with a bound or temporarily bound structure associated with thebrightness increase. However, the nature of the brightness outburst is unclear,and it is also unclear whether the dust or ice released in the outburst couldbe feeding a putative ring structure or if it emanated from it.
