UPCOMING METEOR SHOWERS: JULY 2017

Shower activity in July is concentrated around the end of the month.
Most remarkable shower this month is Southern δ-Aquariids, peaking July 30. Maximum ZHR of this shower is around 25 hr-1 for about 2 days (λsol= 125 degs to 127 degs), while ZHR remains above 20 between λsol= 124 degs to 129 degs. Bright meteors can be found around the maximum, but before and after that, meteors are relatively faint. Two brief outbursts (both with ZHR=40 hr-1) were observed in 1977 and 2003.
For European observers, the Radiant of this shower is above horizon only in night/early morning hours.

Some minor showers are also active around the end of July: Piscis Austrinids can be used for MS predominantly from the Southern Emisphere, while α-Capricornids is characterized by bright meteors with low apparent velocity, that make this shower one of the most spectacular to observe visually. Last α-Capricornids enhancement took place in 1995 (ZHR=10 hr-1); please note that recent observing results suggest that the maximum may continue into July 31st.

There is a chance for meteor activity from Comet C/2015 D4 (Borisov). The orbit is good enough for calculating the timing, but not the activity level. If the miss-distance of the trail will be lower than about 0.0003 au, something may appear on July 29th, 00h10m UT from a radiant in Columba.

Take also advantage of very good Sporadic Meteors rates: Sporadics rates are now approaching annual maximum, which will take place in late summer.


For Radio Observers, the (Theoretical) UT peaks for upcoming showers in July 2017 are as follows:

Piscis Austrinids (Southern emisphere shower)
Active: July 15 - August 10
Maximum: July 28 (λsol= 125 degs)
ZHR: Low (5 hr-1)

Southern δ-Aquariids
Active: July 12 - August 23
Maximum: July 30 (λsol= 127 degs)
ZHR: Medium (25 hr-1)

α-Capricornids
Active: July 03 - August 15
Maximum: July 30 (λsol= 127 degs)
ZHR: Low (5 hr-1)
