July is a month of showers in Tucson. Not only does meteor activity pick up after 6 months of a seasonal lull, but the rains return to the desert after a few months of dry and hot weather. While the rains haven’t arrived yet, they weren’t too far off. The first four nights of the month saw clear skies. The following 3 nights were affected by a brightening Moon, debris clouds from distance thunderstorms and smoke from the Burro fire in the Santa Catalina mountains to the north of us.
The SALSA3 camera system will be operating every night this month, though a few of the nights will be clouded and/or rained out due to the monsoon rains. The clouds may be a real pain during the next few nights due to the Full Moon. Brightly lit clouds have a habit of driving the meteor detection software crazy.
