Bighorn Fire updates, New Accessories tests,
Posted: 4 July 2020
Wednesday, 1 July 2020, dawned clear (with no smoke visible) and calm. The Bighorn Fire, started by lightning on 5 June, had now burned 118,370 acres and was 54% contained. This chart has the progression of the fire from 7 June through 30 June.
Clouds began arriving mid-afternoon on Wednesday as monsoonal moisture began coming into southern Arizona. By late afternoon the view towards the mountain was a sight rarely seen since 6 June.
Due to decreased fire activity and increased fire containment percentage, the Bighorn Fire Incident Management Team ended regular evening updates. I will continue to update my Bighorn Fire reports 2020 page with information as appropriate.
Thursday, 2 July, dawned partly cloudy. The fire was at 118,710 acres burned, 58% contained. Monsoonal clouds increased during the day. A bright rainbow arc with a faint secondary arc was visible in Oracle about 30 minutes before sunset.
Friday, 3 July, dawned mostly clear with increasing cumulus clouds mid-morning. The Bighorn Fire was at 118,807 acres, 58% containment, with some light rain occasionally. Fire activity has decreased, although there are flooding and landslide concerns for many areas. Friday evening the perimeter containment had increased to 73%. The Oracle evacuation status remained at READY.

Slewed to the star Regulus for my initial checks of the new Explore Scientific eyepieces for a future review in Astronomy Technology Today magazine.
1944 MST: the nearly full Moon had risen over the hill to the southeast. It will be full Saturday night, with a very slight Penumbral Eclipse.
I tested the new eyepieces for my review. Once the review appears in the magazine I will posted my review here.
I viewed the Moon, 102X. A slight terminator was visible. This is a handheld afocal 102X photo of the Moon using the iPhone 11 Pro Max taken with the iOS app NightCap Camera (ISO 21, 1/130sec, 0.5X lens).
I also took this handheld iPhone photo (ISO 32, 1/1800sec, 1X lens) showing the slight terminator.
