Although a merger or interaction must have taken place to create the distorted arms in UGC 9829, the two compact ellipticals appear undisturbed on the SDSS.

600/800mm - 24" (6/27/14): faint, small, slightly elongated (core), 15"x12". Often extremely faint extensions (arms) are visble extending NNW to SSE and increasing the dimensions to 30"x12". Brightest in a trio (KTG 61) with CGCG 021-081 1.6' WSW and CGCG 021-083 2.4' SSW.

24" (5/29/14): faint to fairly faint, fairly small, elongated 4:3 N-S, 0.4'x0.3'. The remarkable tidally stretched arms extending north and south were not seen.

900/1200mm - 48" (5/1/19): at 545x; this unusual galaxy contained a bright elongated core 0.3'x0.2'. A spiral arm was attached on the east side and was brightest near the root. It continues as a diffuse, low surface brightness extension to the south and curves slightly, convex to the east, for a total length of ~40". A second faint tidal arm is attached on the NW side of the core. This thin arm extended straight north for 1' with a brightening at the north end. A faint, broken section angling SE from the north tip was not seen.
