November Meteors 2018.

Not much chance of visual meteor spotting over the month , but the radar setup based on the Graves 140.05 MHz signal continued to record data.

The maximum number of meteors detected over November was 2701. The average daily rate was 90 with a maximum of 135 on 20th of Nov.

The average hourly rate was 4 (3.8) with a maximum of 21 between 9am and 10am on the 20th.

The major shower in November is the Leonids, active between the 6 -30 with a peak on 17/18,  Also Taurids active between Oct 12 – Dec 2 with the Southern branch peaking on Nov 5 and the Northern Branch on the 12th.

There are also a number of other minor showers active over the month:

Andromedids  peaking on 27th

Theta Aurigids, 15th -21st peak 19th

Omicron Erianids  14th – 29th peak 22nd

Alpha Monocerotoids 13th Nov – 2nd Dec peak 21st

Chi Taurids peak Nov 2nd.

It is difficult to isolate any one shower in the data, but the hourly data shows a definite peak around the 20th, probably the sum of those showers active during that date.

The final chart shows a comparison of data from 2016 -2018, although levels vary , certainly the 2017 and 2018 data seem to mirror each other.

Next month sees the Geminid shower 6th – 19th peaking 13th /14th, with the moon set at around 22:00 there should be some good viewing around midnight. The Ursid shower peaks on the 22nd but a full moon will make observations difficult. Finally if Comet 46P/Wirtanen peaks as predicted it should be easily visible between the Pleiades and Aldebaran on 16th Dec.

October Meteors

The radar meteor detection based on the Graves frequency detected 2592 meteors during October.

The maximum daily count was 109 on the 14th Oct with an hourly maximum on the same day between 11;00 – 12:00.

This was probably due to the Delta Aurigids which have a peak activity on the 11th but this tends to spread over several days.

The average daily count was 84 and the average hourly count 4.

The Draconids peak on the 8/9 th October and a high level of activity was recorded in the late hours of the 8th , early horus of the 9th.  This meteor stream is linked with Comet 21/Giabcobini-Zimmer and it was thought its latest visitation would cause such an out burst, in fact it was due to an earlier trail of debris from the comet and could have been more spectacular.

The increase in activity can be seen on the data below , see the hourly chart for Oct 8-9.

The epsilon Geminids peaked on the 18th and the Orionids (linked with Halleys comet) peaked on the 22nd.

The hourly and daily plots are shown below as well as a comparison of the daily plots for 2016, 2017 and 2018.

Next month sees the Taurids around the 12th , Taurid fireballs have already been reported ( see and the Leonids  after midnight on the 17/18, the moon shouldn’t be much of a problem.

August Meteors

Although not visually very active (clouds again!!) the Perseids were very prominent in the  radar data. In my post mid august the data showed a maximum daily rate of 313 on the 13th with a maximum hourly rate of 28 between 2-3am on 12th, and as the hourly plot showed the main activity was between 2 – 8 am hence missed by lots of people even if clear, Ed and Dave at Solarfest went to bed too early!!

The meteor count total for the month was 2999, with an average daily count of 97 and average hourly rate of 4.

The hourly and daily plots are below and for comparison below these  the August  daily count for the last 3 years, interestingly the shower peaked on the 13th in 2018, 2017 but on 12th in 2016, this however is only the daily count and a different set of conditional actions for recording events is now in use.

The final chart is a reposting of the 2018 shower data.

Perseid Shower 2018

The Perseids have been and gone, maximum hourly count was 28 between 2-3 pm on the 12th and the max daily count was 313 on the 13th. The hourly plot between 10th and 16th shows the daily shower distribution quite clearly, maximum activity picking up for 2pm onwards on most days , hence not many being seen, also the majority of counts were of low duration, so most not very bright, there were some longer duration signals associated with fireballs but not many and certainly not bright enough to trigger the all sky camera which I had running when sky was clear.( which wasn’t very often)

The Perseids are coming!

Monitoring of meteor activity using the reflection of the Graves radar signal with the fundongle pro+ shows a gradual increase in the daily count since start of month ( 78),  up to 109 for yesterday and the maximum hourly rate has now risen to 15, also noticeable is the higher frequency of longer duration events, that could indicate fireballs such as this trace below. The peak is due on the eve of 12/13 Aug but also possible to view on 11/12th , however forecast is not good for either night !! However with the increase in activity and higher incidence of long lasting trails it might be worth having a look on the eve 10/11th as at least it is supposed to be clear!

July Meteors.

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.” (

Moderate Activity:

Radiant Duration Maximum
Southern Delta Aquarids (SDA) July 14-August 18 July 28/29

Minor Activity

Radiant Duration Maximum
Alpha Lyrids July 9-20 Jul. 14/15
July Phoenicids (PHE) July 9-17 Jul. 14/15
Alpha Pisces Australids July 16-August 13 Jul. 30/31
Sigma Capricornids June 18-July 30 Jul. 10-20
Tau Capricornids June 2?-July 29 Jul. 12/13
Omicron Draconids July 6-28 Jul. 17/18

The total number of meteors detected in July (2018) was 1824, with a mean daily rate of 59 and mean hourly rate of 2.5.

The maximum daily rate was 87 on the 26th July and the maximum hourly rate was 11, between 3-4am on the 27th and 30th.

The daily and hourly rates are shown in the first two charts below

These maxima coincide with the SDA shower and the trends over the month reflect the observation quoted at the start of this post. The trend of increasing activity towards the end of the month is borne out in the last chart below which compares the data over the last three years, the suggested trend is more pronounced in the 2016 and 2017 data than this year .

The Perseids are already with us peaking on the night of the 12/13th August, and with a new / very young moon there should be good viewing conditions as long as the clouds stay away.

June Meteors

No major activity in June , the June Lyrids the most active around the 15th/16th of June, the peak is distinguishable on the daily count plot. The peak activity around the 10/11th, is probably the combination of the Theta Opiuchids and Saggitariids.  The rest of activity during the month a combination of the many minor showers present.

The dip in the daily rate on the 6th is due to Graves being off line between 01-05 hrs. The activity has dropped of to about 50 meteors / day towards end of month and has continued at this rate into July which is a relatively “quiet” month.

The plot is similar to the daily plot from 2017, although rates lower( this is probably dependent upon the density of the debris field the earth passes through )

I’ve listed the showers for June below as are the daily and hourly plots for June 2018 and the daily plot for June 2017.

Daylight Activity:

Radiant Duration Maximum
April Piscids April 8-29 Apr. 20/21

The total meteor activity detected for April was 1790.

The average daily rate was 60 and the average hourly rate 2.5

The max hrly rate was 11  during the hours of 9 & 11 on 30th April

The max dly rate was 93 on 23rd April with hourly counts of 10 during the hours of 4, 9 & 11.

Maximum activity for the Lyrids occurred during daylight as did a lot of this months activity.

The daily rate graph and hourly rate graph are listed below, the Lyrid max is marked on both, the daily rate for 2017 is also included for comparison, it would appear more meteors were detected this year. The month of May brings the Eta Aquarids over the weekend of the 5th/6th, which will be competing with a bright waning Gibbous moon.

The total meteor activity recorded for the month using the fundongle pro+ on the Graves frequency was 1116, there was a daily average of 36 with an hourly average of 1.5 The maximum daily count was 60 recorded on 19th March as was the max hourly count of 13.

This peak activity coincided with the peak activity of the Beta leonids, delta mensids and eta Virginids. Other minor peaks can be identified using table above.

A post on the UK Radio Meteor discussion group on the 19th flagged up a long duration event picked up by an observer at Emsworth in Hampshire., I didn’t find any visual reports of this daytime event.

Checking my logs this event had also been recorded at Barton, although spread across two screens.

The event was also recorded in Lincoln ( note the vertical, rather than horizontal waterfall screen)

Also recorded in Loughboro’

April is now with us and as well as several minor showers there is the Lyrid shower to look forward to over the 21/22 of the month , peak 11:00 – 22:00 BST on 22nd April. Moon in its first quarter should not cause any problems and for Lunar observers the Lunar X and V are at peak visibility around 21:40 BST on sun22 April.


clear skies
