Changing conditions

The last few nights have seen some bizarre changes in observing conditions. We've gone from some relatively average conditions (seeing around 0.6" for those who know what I mean) to absolutely stunning seeing (~0.3", natural) and within half an hour to a terrible upper atmosphere that our guider couldn't cope with followed almost immediately by a mini ice storm and freezing fog. Tonight the seeing remains awful and highly variable but I'm sure the atmosphere will sort itself out soon.

Down below, the conditions have been changing daily, but they did allow a quick view of the Hualalai volcano with little cloud between it and us at Mauna Kea's summit. Unfortunately, the unusual evening view was spoiled by vog which you can see floating around below Haulalai's summit. Still, the vog does make for an unusual looking picture.
