Aug 6 Meteors
August 7, 2014
That’s more like it. With the software timing issue fixed (it was shutting down my system a good 2-3 hours prior to dawn), my nightly total jumped from ~20 to 45 meteors. The higher number really highlights how the last 2-3 hours of the night is best for meteor watching.
Two showers account for 24 of the 45 meteors. The Southern Delta Aquariids peaked a week ago but are still producing a good number of meteors. The Perseids are the main shower visible right now. They are building towards a peak on the night of August 12/13. According to visual reports submitted to the International Meteor Organization (IMO), the Perseids are already producing ZHR rates of ~20 per hour. [Note, that ZHRs are idealized rates for perfect observing circumstances. Most observers will see lower rates in the 5-10 per hour range.] On the night of the peak, ZHRs may reach ~60-150 per hour though a very bright near Full Moon will greatly decrease the rates actually seen.
