UPCOMING METEOR SHOWERS: JUNE 2021
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 2021, 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 daylight MS-Dxing. Note that the two maxima tend to blend into one another, and 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, which produced unexpected activity in 1998 (ZHR up to 100 hr-1 for more than half a day) and 2004 (ZHR up to 50 hr-1 with similar length).
The last perihelion passage of parent comet (7P/Pons-Winnecke) was in 2015; no peculiar activity is predicted for 2021 return.
For Radio Observers, the (theoretical) UT peaks for upcoming showers in June 2021 are as follows:
Arietids (daytime shower)
Active: May 14 - June 24
Maximum: June 07, 10h UT (λsol=76.6 degs)
ZHR: High (30 hr-1)
ζ-Perseids (daytime shower)
Active: May 20 - July 05
Maximum: June 09, 12h UT (λsol=78.6 degs)
ZHR: High (30 hr-1)
Active: June 22 - July 02
Maximum: June 27 (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)
