What is red numeral time in Cluster (F9)?

[ac5aa]

I notice that some spots are indicated with red numerals in the time field, and these relate to the spots in the smaller window preceded by an asterisk (*). I can't determine what this signifies, and I don't see any notes in the manual about it. Thanks in advance!

Duane,

The red time in the cluster window and the * in the small cluster denote stations which utilize LotW.
