I was out most of last night observing 0345-0645 and 0700-1015 UT. I saw no Perseid fireballs and fewer negative magnitude Perseids than the previous morning.
The parking lot lights at the Story County Conservation Center at McFarland Park go off at 10:45 CDST. The LM was a little better than yesterday. On drive home saw evidence of horizon haze up to 3 degrees, but still not bad for Iowa in summer. I deployed a black umbrella to block the bright Moon light.
The session got off to a bad start. I saw two Perseids right away, then it was a half hour before I saw another meteor. There were several other long lulls in which no Perseids were seen. It was nearly two hours before I saw the first negative magnitude Perseid.
The brightest meteor of the session was a - 5 yellow Antihelion that ended near Capella. The next brightest meteor was a - 4 yellow Kappa Cygnid. The brightest Perseid was - 3. The brightest ATR was - 2. No apparent SDA's or ERI's. Trains were more apparent than yesterday morning due to slightly better LM.
