Another fine night, USA 193 bright & a Lacrosse 3 flare

Friday evening and Sunday evening saw two other observing opportunities. On Friday it remained restricted to Lacrosse 3 & the Lacrosse 5 rk (97-064A & 05-016B), as clouds came in at a certain point (this made me miss a predicted -8 Iridium flare alas). I saw Lacrosse 3 (97-064A) flare to mag +0.5 however at 23:30:44 UTC (Jul 20).

Sunday night was very fine however, and I catched Lacrosse 3 & 4, plus IGS 4A/R2 (07-005A) and USA 193 (06-057A). The latter was quite bright (+0.5) while passing in the northwest. The second of the two images below shows it as it is just disappearing out of sight behind the roof. The other image shows IGS 4A/R2.

USA 193 was 2.3s early relative to Ted's elset 07202.04020244.
