Jill, I'm not an expert (more of a lurker), but perhaps I can help a little. If we look at your 3 sats at a specific moment in time (10:00-10:01), you have the following: 10:00 (00) 4.9 mg az=74.38° ENE ht = 58.82° 10:01 4.0 mg az= 70.72° ENE ht = 19.88° 10:00 4.1 mg az= 70.48° ENE ht = 34.41° While the time, approximate magnitude, and azimuth are close, the elevations are not. The guide at this link shows a few rules of thumb (and finger!) to estimate angular distances: https://oneminuteastronomer.com/860/measuring-sky/ Your 1st sat would've been two 'pinkie thumb spans' or almost 6 fists. The second a little less than 1 pinkie thumb span or two fists, and the third would've been 3 fists.

Last night (June 22, 2018) I had a possibility of three satellites in the same area. I am going to post the info I have and maybe someone can help me. I would also please request the why you chose one over another as I was not able to eliminate out of these three. I was able to eliminate a fourth because the "exit" was in the wrong location. I am at lat 45.1856 N lon -67.2736 W 91 ft EST -4 UT Eastern Maine USA (I get lon wrong as I work to understand the difference between a neg W or an E or a neg E or an W relative to Greenwich). IGS Radar 5 (42072 2017-015A) 10:00 (00) 4.9 mg az=74.38° ENE ht = 58.82° 10:02 8.1 mg az= 360/0° N I have no height listed as it would be lost to Earth's shadow. LKW-1 (43034 2017-077A) 9:59 4.4 mg az= 123.58° ENE (adding this line for reference, could not see due to houses in area) 10:01 4.0 mg az= 70.72° ENE ht = 19.88° 10:05 invis az= 360/0° N ht= 5 ( this would be below other houses) SUPERVIEW 1 04 (43100 2018-002B) 9:58 4.5 mg az= 124.03° SE ht= 19.36° ( this would be behind a house) 10:00 4.1 mg az= 70.48° ENE ht = 34.41° 10:05 8.0 mg az= 0° N ht = 5 Basically, I noticed the satellite in the ENE sky and followed it towards N as expected. It had a GREEN (like green smoke) elliptical (bullet shape) but flattened flare that was parallel to the satellite at +/- N. I was not watching the time or direct compass as I am still learning and in the WOW stage. Right after this, the satellite was not seen. All three of these possibilities could be the satellite to the mg at ENE and the direction travelled. The satellite slightly dropped in mg but not a big difference. The drop off at N is explained by all three. This satellite was not as fast as ISS. How do I eliminate the possibilities, such as which satellites would emit such a flare. Two of the three are Chinese spy satellites, I mean Earth Observation satellites. I am more trying to learn how to determine which satellite it was. I encounter LKW 1 and 2 often so that has a big possibility. The two others are new to my sighting. I do suspect IGS is my best guess due to the height in the sky as I believe the height was ballpark 45°. Thank you, Jill McDonald Sighted with naked (eye glasses) eyes from side lawn.
