The group appears as a gray smudge. It looks like two spots to me.

I went out for one satellite and got three on the same track one behind the other. This is usually spay satellites like Lacrosse that are used for change detection but at least the last one in this case was an Iridium communications satellite.
CalSky lists three satellites passing on the same track at 2056 (NOSS 3-3 (A), NOSS 3-3 (B), and NOSS 3-3 (E), and a Cosmos and a Lacrosse that followed somewhat similar tracks at 2045 and 2053 respectively.
I am not sure which of these satellites I saw, but I know I saw an extremely bright flare.

| Comments | This was like a visible pass and a flare combined. I thought when the second satellite came through at about the right time that I had been skunked because CalSky says this is Iridium 90 and that it is a spare satellite and may not flare when and where they predict it or at the magnitude they predict, but it flared as it approached Zosma, the haunch of Leo and faded before reaching 60 Leo. The flare was long and bright and the fade was very rapid and disappearance occurred down below the belly of Leo between M65 abd M105.
