July 26/27/28 Meteors – Peak of the SDA, CAP and PAU showers

The monsoon finally took a break here in southern Arizona. For the first time in over a month, the night sky has been clear of all clouds and haze. The timing couldn’t have been better since this week marks the peak activity of a number of minor showers. The Alpha Capricornids and Piscids Australids are both capable of producing 1-5 meteors per hour from a dark site. The Southern Delta Aquariids are even better at 10-20 meteors per hours from a dark site.

The best meteor of the past 2 nights was this early evening Alpha Capricornid. The video below is playing at ~1/2 speed. Still this was a rather slow meteor which is common for Alpha Caps.

CAP

The high number of detected meteors confirms that activity was up. Even with lots of active showers, about half f the activity was from Sporadic meteors that are not members of any known shower. Of the active showers, the Southern Delta Aquariids lead the pack, as expected. The Alpha Capricornids come in a close second with the Perseids (still weeks from their peak) producing a healthy number as well.

    10.50pm 28th July, Night Sky over Ireland spotted a beautiful meteor that was very bright and after 12seconds or so flickered out. Amazing!
