Weather: T: -52C, RH: 56%, wind: 4kn at 207, Sky conditions: FEW

Where collected: Table, 10m E of MSF

Description: No precipitation. Surface hoar frost. Dominantly 1000 micron bullet rosettes, occasionally with irrecular crystals attached. The bullet rosettes on the upwind slide were often flattened or broken. Downwind slide bullet rosettes are very three dimensional and intact. The tiny (< 50micron) crystals all over the slides are likely formed out of small drops of water left on the slide after cleaning.

Other comments: I have started taking a before/after picture centered on the scale to control for spontaneous crystal formation/contamination due to slide handling while taking pictures. Upwind and downwind slides were similar, except as noted above. Pictures below DSC_0033 are downwind. Pictures above DSC_0033 are upwind.
