July 21/22 Meteors

Bob notes the following about this year’s Southern Delta Aquariids: “The lack of Delta Aquarids so far this year seem to validate the new activity period proposed for this shower (July 21 through Aug 30). Rates from this shower should now increase substantially, reaching maximum activity on Thursday July 30.”

Last night looked promising in Tucson with no thunderstorm activity and little in the way of clouds. I was disappointed that only 7 meteors were picked up. Though there were no T-storms in the Tucson area, a large complex of storms to the northwest pushed a gust front through the area last night. The high winds caused a dust storm that covered the Tucson area and made it difficult to observe much of anything last night.

July 11/12/13 Meteors

Well this is a little more like it. Last night’s rates were still rather low but the night before produced 15 meteors. Clouds have been less of an issue lately as the monsoon enters one of its down periods. That should end in a few days though.

The last 2 nights have also seen some consistent activity from 2 of July’s better showers, the Alpha Capricornids and the Southern Delta Aquariids. Both showers will gradually ramp up in activity until the time of their peaks on July 27/28/29.

From Bob’s notes: “With the moon becoming less of a problem, meteor rates finally kicked into high gear. Now I just need some better weather as clouds interfered with observations on the 11th and 14th.”
