Summary: Quick check to clean mirrors, field has been sprayed, will flood shortly

I arrived at about 8:15PDT. It was clear, sunny and mild with a strong breeze. This was a quick stop to check the 7700 mirrors and 7500 windows incase recent spraying of the field had fouled them.

The 7700 RSSI was 26. The mirror was dusty, but did not look like there was any residue from the sprays. After cleaning the RSSI was 67 and the LI7500 AGC was 6.7.

It looks like they sprayed the field with a tractor instead of by air. (I saw a helicopter spraying corn on Sherman). I did not notice if the LAI transect laid out last time was still there or not.

There was a little water along the edge of north check and it looked like Jim was farther out in our check working to get the water flowing.
