Meteor Activity Outlook for August 1-7, 2020

During this period, the moon reaches its full phase on Monday August 3rd. At this time, the moon is located opposite the sun and remains above the horizon all night long. This weekend the nearly full moon will set an hour prior to dawn, allowing a short but dark glimpse of the early August activity. By Thursday, the short, dark portion of night will have shifted to the evening sky in the hour following dusk.

Meteor Activity Outlook for July 25-31, 2020

During this period, the moon reaches its first quarter phase on Monday July 27th. At this time, the moon is located 90 degrees east of the sun and sets near midnight. This weekend the more active morning sky will be totally free of interfering moonlight. As the week progresses though, only the few hours just prior to dawn will provide dark skies.

Meteor Activity Outlook for July 18-24, 2020

During this period, the moon reaches its new phase on Tuesday July 21st. At this time, the moon is located near the sun and is invisible at night. The moon will be located near the sun during this entire period; therefore, meteor observations can be held at any time of the night without lunar interference.

Meteor Activity Outlook for July 11-17, 2020

During this period, the moon reaches its last quarter phase on Monday July 13th. At this time, the moon is located 90 degrees west of the sun and rises near 0100 local daylight saving time (LDST). As the week progresses the waning crescent moon rises later in the morning with each passing night. This allows the window of dark skies to increase as the week progresses. The most active hours just prior to dawn will have slight interference from moonlight but one can overcome this simply facing in a direction where the moon is not visible within your field of view.

Viewing the Southern Delta Aquariids in 2020

One good thing about a Perseid maximum with lunar interference is that it guarantees that two weeks prior that the Southern delta Aquariids (SDA) will peak under good conditions. Such is the case in 2020 when the last quarter moon will diminish the Perseid peak. The SDA's will peak on July 29th with a waxing gibbous moon setting just as the SDA radiant culminates in the southern sky.

    During this period, the moon reaches its full phase on Sunday July 5th. At this time, the moon is located opposite the sun and remains above the horizon all night long. As the week progresses the waning gibbous moon rises later in the evening with each passing night. This allows for some early evening meteor observing under dark skies. Unfortunately, this is also the time of the lowest meteor activity of the night.

    During this period, the moon reaches its first quarter phase on Sunday June 28th. At this time, the moon is located 90 degrees east of the sun and sets near 01:00 local daylight saving time (LDST). As the week progresses the waxing gibbous moon remains longer in the morning sky with each passing night. This narrows the opportunity to view meteor activity under dark conditions from many hours early in the period to almost nil late in the period.

    During this period the moon reaches its last quarter phase on Saturday June 13th. At this time the moon will rise near 02:00 local daylight saving time (LDST) and will remain in the sky the remainder of the morning. This will compromise late morning viewing but successful meteor observations can still be attempted if one keeps the moon out of their field of view. As the week progresses the waning crescent moon will rise later each morning, becoming less of a problem with each passing night.

    During this period the moon's phase wanes from full to nearly half illuminated. As the week progresses the waning gibbous moon will rise later each night, providing a small window of dark skies between dusk and moonrise. Unfortunately, meteor activity during this time of night is low, but this is offset by the opportunity for younger observers to view the dark evening sky prior to bedtime.
