Hi, I sighted ATEX this evening (1852 local, 0052 UT 10 Dec 98). It did not appear to be steady. It dimmed to about my limiting magnitude (~7 with 7x50 binocs) and then brightened to perhaps six. Didn't try to time it, but period appeared to be on the order of five seconds or so. Observed it through three or for periods. Have there been any reports of ATEX tumbling?
