While looking for a few suitable satellites for an observing session tonight with my young niece and nephews, I discovered that Meteor 2-13 and its rocket stage will be in close proximity tonight and tomorrow. The rocket will lead the payload by about 17 s at the 01:14 UTC 2 Sep pass, visible from eastern North America. By tomorrow night's pass (01:30 UTC, 3 Sep), the payload will have overtaken the rocket stage, leading it by about 1 second. Observed at high elevation above the horizon, the objects will be within about 3 deg of each other. This kind of event is not all that rare, given the large number of payload-rocket pairs that are in nearly identical orbits, lapping one another every so often. Still, it can be a neat sight to see two satellites traveling together in apparent formation. Observers around the world will have the opportunity to observe the two objects in varying degrees of proximity tonight and tomorrow. Here are their orbital elements: Meteor 2-13 5.0 1.5 0.0 6.5 1 16408U 85119 A 96242.14091585 .00000018 00000-0 16353-4 0 2319 2 16408 82.5353 286.2549 0017014 111.6979 248.5982 13.84731650539485 Meteor 2-13 r 7.4 2.4 0.0 5.5 1 16409U 85119 B 96242.14004498 .00000003 00000-0 24824-5 0 5249 2 16409 82.5368 286.8472 0015725 120.0392 240.2325 13.84483101539477 Ted Molczan
