Tuesday, 6 September 2022, was a mostly clear but busy day that started early with a planning meeting for the "David H. Levy Arizona Dark Sky Star Party & The Oracle Dark Sky Cultural Festival". See the Arizona State Parks & Trails press release.

That was followed by an all afternoon and evening meeting with the Arizona Line Siting Committee at Biosphere 2 to discuss the SunZia Transmission Line Project that is proposed to pass near Oracle State Park, an ecologically sensitive location and International Dark Sky Park. For several years I have been representing Oracle and Oracle State Park in discussions with the company doing the SunZia Project, government agencies, and local citizens about the Transmission Line Project and its impact on the local area.

I didn't get home until late, and with another long day of activities on Wednesday, 7 September, I didn't open the observatory that night. Wednesday became overcast, and with possible thunderstorms in the coming days due to moisture from Pacific Hurricane (then Tropical System) Kay, I put the Dome Cover ON.

Thursday morning, 8 September, I was on another planning meeting for the event in Oracle (we have had many such meetings over the past several months!). That evening I participated in a meeting with local ecological support individuals and the SunZia Transmission Line Project company.

On Friday, 9 September, the Arizona Line Siting Committee approved the SunZia Transmission Line Project with some important conditions that resulted from local community involvement in the process. In particular, the contractor and the Committee acknowledged the local support for Dark Skies and concerns about visual impacts. The contractor committed to "actively work with the community of Oracle" to mitigate impacts. So, community involvement has made a major difference in what would have otherwise been a less desirable outcome. The contractor has asked me to continue to assist them by advising them on lighting alternatives, which I'm happy to do. The Project now goes before the Arizona Corporation Commission for final approval.

Friday night had a thunderstorm (0.14"). Sunday night, 11 September, had a brief thundershower (0.04"). Before sunrise Monday, 12 September, had another brief shower (0.08"). Received this alert Monday afternoon; not something we get very often in Arizona.

The actual warning area was many miles from Oracle though. A brief rainshower (0.02") did happen. Cloudy skies continued until Thursday, 15 September.
