Because of the unfavorable sky position, the main reward now is likely 
to be semi-snapshots.? Previous rebrightenings/echoes have lasted a 
couple of weeks.? But it's a very good target to schedule for "last 
object of the night".? Watch out for that onrushing twilight!

I'll send out a longer recommended-target list tonight.? But here are 
two high priorities:

QS UMa (the old "UMa 6"). David Cejudo has been carrying out great 
coverage from Spain.? But we really need some comparably intensive 
coverage from the USA (the 10-hour period certainly rewards *extensive* 
spread in longitude).

AM CVn. Similar comment, only now it's the Euros that have been not so 
active.? So, in this Olympic year, let's get all (northern ) nations on 
board.? Lengthy time series are quite advantageous, because the three 
distinct periods (1051 s, 1029 s, 1011 s) need time to separate cleanly 
in phase.? But don't tamper with the 2.0 airmass rule; these signals are 
extremely precise, so it behooves us to be as precise as conditions allow.

Congrats again to Joe U for keeping the faith on Maxie!
