UPCOMING METEOR SHOWERS: MAY 2017
η - Aquariids is the most prominent shower in May; its predicted maximum for 2017 will fall on May 06, 02h UT. This shower, related to the rich stream associated with comet 1P/Halley (as the Orionids in October) , is characterized by a broad maximum, sometimes with a variable number of submaxima. IMO analyses based on data collected between 1984-2001 indicate that ZHRs are generally above 30 in the period May 3-10. The peak rates appear to be variable on a roughly 12-years timescale, due to influence of Jupiter. According to this model, the minimum rates should have been observed around 2014 - 2016, while the most recent highest rates should have happended around 2008-2009 (with ZHR up to 85 hr-1). In spite of that, ZHR values reached 65 hr-1 in 2011 and 70 hr-1 in 2013. But Given the normal return in 2014 and 2015, such a display seems unlikely to repeat this year: Model calculations indicate that ZHR could reach 50 hr-1 in 2017.
Please note that η - Aquariids radiant is above horizon (thus making the shower usable for MS) in Europe only (approximatively) in very late night and morning hours. While southern Europe stations will be able to "see" the radiant till early afternoon, in northern Europe skies the radiant culminates at reletively low elevation so an observer is able to see the radiant for much less time.
Some daytime showers (o - Cetids, peaking May 20th being the most significant ) will also be active this month; in addition to increasing Sporadic Meteors background, they will provide good conditions for MS DXing.
For Radio Observers, the (Theoretical) UT peaks for upcoming showers in May 2017 are as follows:
η - Aquariids
Active: April 19 - May 28
Maximum: May 06, 02h UT (λsol= 45.5 degs)
ZHR: HIGH (50 hr-1)
η - Lyrids
Active: May 03 - May 14
Maximum: May 09 (λsol= 48.0 degs)
ZHR: Low (3 hr-1)
ε - Arietids (Daytime shower)
Active: April 24 - May 27
Maximum: May 09, 09h UT (λsol= 48.7 degs)
Arietids (May) (Daytime shower)
Active: May 04 - June 06
Maximum: May 16, 10h UT (λsol= 55.5 degs)
o - Cetids (Daytime shower)
Active: May 05 - June 02
Maximum: May 20, 09h UT (λsol= 59.3 degs)
