I arrived about 7:50PST. It was clear, sunny, warm and warming with little to no wind. Little change in vegetation. Dragon flies are gone, and grasshoppers are greatly reduced.

I worked on fixing the tipping bucket problem. I read the CR23X’s status info in the *B mode:
Program Signature 23594
OS Signature 36790
K bytes memory 1664--
EO8 00
Table overruns 00
OS version 10916
OS revision 0019
Lithium battery 2.8476
Low 12V 00
Flash errors 00
Flash erase 0.000
Low 5V 00
Program time 2102.8
Panel Temperature 21.212
Coprocessor Rev 02
Coprocessor status 00

At Campbell’s recommendation I wrote a short program with Shortcut for only the tipping bucket, and this seemed to work. However, when I wrote the same program by hand using Edlog it did seem to work. The 23X has had a factory check relatively recently – last cal was July 13, 2007.

I also noticed that the bird deterrent stick on the NR-Lite was casting a shadow across the upward sensor face (see photo). I removed the stick.

I cleaned the radiation sensors.

I left for Tonzi about 10:30PDT.
