The Arietis and Zeta-Perseids are two swarms that we expect to peak in early June. The Arietíd activity starts on May 22 and ends on July 2, while maximum očakávame 7.júna o 4.00 UT. Predpovedaný je maximálny počet odrazov za hodinu (ZHR) okolo 60. Najvhodnejšie časy pre spojenia v osiach SV – JZ: 5 – 7 UT, V – Z: 8 UT, SZ – JV: 9 – 12 UT, S – J: 3 – 6 a 10 – 13 UT.
Zeta Perseidy začínajú byť aktívne od 20.mája do 5.júla. Maximum očakávame 9.júna o 1.00 UT s maximálnym počtom odrazov za hodinu približne 40. The most suitable times for connections in the NE – SW axes: 6 – 8 UT, NW – SE: 11 – 13 UT, S – S: 4 – 7 and 12 – 14 UT. Both the Arietis and Zeta-Perseids maxima tend to merge into one, creating a strong response. There are also indications that the maxima of these swarms occur about a day after the time given here.
