The (mostly) good weather continues. Rhodri Evans was the observer for UC03. He used GRIM2 for polarimetry and had a very successful run. Austin Tomany was the observer for UW12, with SPIcam. Most of his time was clouded out by a rather fast moving little storm that was in central California at sunset! Austin waited patiently for the weather to improve.
