below are the daily and hourly rates for meteors this month, average daily count of 48 and av hourly count of 2. No major showers,
Next month the Orionids peaking on 21st, the activity is already at 80+ counts with the Sextantids (daylight shower) and the Eta Cetids and October Cetids all active at the start of October.
September Meteors: Minor Activity
Here is the July meteor data based upon radar backscatter from Graves. As commented by http://meteorshowersonline.com/july_radiants.html
“Although the July radiants do not individually produce strong rates, activity from the Aquarius and Capricornus regions in July and early August, as well as minor activity from other radiants, cause hourly rates to basically rise between the middle and end of July for observers in both the Northern and Southern Hemispheres. Therefore, clear, moonless nights can be quite enjoyable for anyone observing during late July. “
there is a definite increase in activity towards end of month, where we are also entering the Perseid stream ( July 23 – Aug 22nd) and there has been a noticeable increase in fireballs picked up by NASA all sky monitors ( see Spaceweather.com)
I have also combined last years daily counts with this years for comparison:
although the count rates vary, there is some mirroring of variation early in the month, but there appears to be an increase rather than decrease in activity during the latter stages of the month. Notice also the diurnal nature of activity, particularly during the second half of the month, where activity is very high during the early hours of the day ( see Hourly meteor rate) .This is a good pointer to observing the Perseids later this month, with peak activity from midnight , through the early hours of the 12-13 Aug, a waning Gibbous moon will be rising around midnight which might interfere with viewing, but it stays relatively low in the sky as the Perseid radiant climbs higher. The shower is active from July 23 till Aug 22nd with best views during the nights of the 11, 12 and 13 Aug. Definitely worth getting those all sky cameras we have made up and running to record shower activity.
below is the daily and hourly rates of meteor detection using Graves radar signal, no major showers this month, month started with continued high count from end of May, then varied with combination over various showers overlapping during month, possible Graves “down time ” early in the month, from morning of 2ndJune to morning 3rd June.
Below are the daily and hourly counts of meteors detected from radar echo’s during March, no major showers but several minor showers during the month which overlap and increase count. See http://meteorshowersonline.com/march_radiants.html.
||February ??-April ??
February is traditionally a quiet month for meteors, with no major showers, as listed below courtesy of http://meteorshowersonline.com/

The peaks of these minor showers can be picked out over the month, average daikly count was 13.5 , with a maximum of 20.
Hi, here are the radar meteor observations for January.
The main activity was the Quadrantids on Jan3/4, there were several other peaks of activity caused by the combination of other minor showers during the month, particularly:
Jan 5th-9th , Gamma Velids and Rho Geminids
Jan 16th – 18th Jan Bootids, Eta Craterids, Jan Draconids.
Jan 20th -31st Canids, Eta Carinids, Alpha Hydrids, Alpa leonids,
The coming months of February and march have no major showers, just a snall number of minor showers. The next main shower will be in April the Lyrids peaking on April 22nd.
below are plots of Geminid activity as picked up by reflected radar from Graves.
First Plot shows Daily activity from 1st Dec to 15th Dec, Geminids peaking over the 13th / 14th. The fall off of activity is also a lot greater than the build up.
Looking in detail at the hourly count over the period of the 12th -15th Dec, the peak activity occurred during the period from 12:00 on the 13th to approx. 12:00 on the 14th.
Next up are the Ursids, peaking Dec 22/23 with radiant in Ursa Minor, this comet shower is associated with comet 8P/Tuttle, the moon won’t be a problem, so lets hope for clear skies.
