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 we expect the maximum on June 7 at 4:00 UT. It is predicted maximum number of rebounds per hour (RHR) around 60. The most suitable times for connections in the NE - SW axes: 5 - 7 UT, E - W: 8 UT, NW - SE: 9 - 12 UT, S - S: 3 - 6 and 10 - 13 UT.
The Zeta Perseids begin to be active from May 20 to July 5. We expect a maximum on June 9 at 1.00 UT with a maximum number of reflections per hour of approximately 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.
