UPCOMING METEOR SHOWERS: JUNE 2017
June is known for the return of three remarkable daytime showers. Major showers Arietids and ζ-Perseids, peaking respectively on June 7th and June 9th in 2017, are both characterized by a broad maximum (with possible submaxima) and high ZHR value, thus making first half of June one of the best periods of the year for MS-Dxing. Note also that there are some indications these two June shower maxima now each occur up to a day later that indicated above.
For both showers, radiant rises above horizon in very late night and culminates in late morning in european skies; in Central Europe (and lower latitudes) the radiant elevation is even too high around midday, thus lowering radio efficiency. For both showers, radiant sets in late afternoon. For central Europe observers, best geometric efficiency can be found in early morning (favoring N-NE and S-SW directions) and early afternoon (favoring N-NW and S-SE directions).
Even daytime β-Taurids, peaking June 28th, is characterized by fairly good ZHR.
May be worth checking also June Bootids (peaking June 27), since two unexpected returns took place (1998, ZHR= 50-100 hr-1 for more than half a day; 2004, ZHR=20-50 hr-1 with similar length), due to material shed by its parent comet (7P / Pons-Winnecke) in the past and now lying in slightly different orbits than the parent comet itself. On the other hand, some other predicted returns (as in 2010) resulted in very poor rates, so the dynamics of the stream is not fully understood. Anyway, since parent comet's perihelion passage was in early 2015, it's better to check meteor rates around predicted maximum day, although no rate enhancements are predicted for 2017.
For Radio Observers, the (Theoretical) UT peaks for upcoming showers in June 2017 are as follows:
Arietids (daytime shower)
Active: May 14 - June 24
Maximum: June 07, 10h UT (λsol=76.6 degs)
ZHR: HIGH (60 hr-1)
ζ-Perseids (daytime shower)
Active: May 20 - July 05
Maximum: June 09, 12h UT (λsol=78.6 degs)
ZHR: HIGH (40 hr-1)
Active: June 22 - July 02
Maximum: June 27, 09h UT (λsol=95.7 degs)
ZHR: Variable but typically low
β-Taurids (daytime shower)
Active: June 05 - July 17
Maximum: June 28, 11h UT (λsol=96.7 degs)
ZHR: Medium (20 hr-1)
