The updated elements below are based on observations by Russell Eberst and Leo
Barhorst:

The distance between the two payloads has increased to 202 km at epoch time of
the elsets above, but the drift rate is slowing down.

During the first week the daily distance drift rate between the two NOSS 3-8
payloads was similar (~32 km/day) to that shown by the NOSS 3-7 payloads during
the first 10-14 days after their launch in 2015.

But the trend for NOSS 3-8 is since day 8 starting to deviate from this as the
daily distance drift rate is slowing down (currently to 14 km/day and over the
coming days it likely will slow down more).

I have clear skies currently, hopefully they last untill the passes of coming
night. Unlike Leo, I was clouded out last night.
