Park entrance sign
Glacier Bay NP&P
"Set up 100' off road from the Park entrance sign in a clearing of small trees in the muskeg. Perfectly clear night but aurora was readily visble at end of astronomical twilight to the north and northeast. No visible light domes from either Gustavus or the more distant Juneau. The Milky Way was easily visble overhead but faded into the brightening aurora to the north. Daytime visibility was 100 miles + while flying in to Gustavus earlier in the afternoon. Was able to see 12 stars in the Pleadies naked eye. Stars visible to the horizon in all areas except where the aurora was present. Frost was quick to coat all of the equipment. SQM reading of 21.63."
