The main shower in April is the Lyrids, but as the table below shows there are other showers present as well.
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.
March is not blessed with a conspicuous meteor shower but there are plenty of minor showers overlapping.
||February ??-April ??
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.
February is not noted for its meteor showers, only a handful of minor showers and some daytime showers.
The radar reflections using Graves, gave a total count of 1140 meteors, with an average daily count of 41 and average hourly count of 2 (1.7), the max hourly count observed was 7 and max daily count 62. The contributions to activity from the Centaurids , Leonids and Capricornids are discernible on the charts below. March is another month of no notable shower, but lots of minor showers.
The main meteor activity this month around the 3rd/4th of January with the Quadrantids peaking in the early hours of the 4th Jan. Graves decided to go off line between 09:00 and 15:00 on the 3rd Jan. ( see red block on hourly plot).
The average hourly rate during the month was 2.2, with an average daily rate of 52.3. The variations during the month are due to the combinations of minor showers during the month, these are listed in table below.
I omitted the total count for 2017 in my new year post, this was 16,727with an average daily count of 46. It will be interesting to see what Andy’s magnetic collector picks up over the year.
New year celebrations caught by the all sky camera.
Below are the daily and hourly meteor counts for December, the peaks for the Geminids and Ursids are clearly shown. Unfortunately Graves went off line between 20:00 on 13/12/17 and 08:00 on 14/12/17. The increase in activity on 31st is beginning of Quadrantids, which will be peaking on the 3/4 Jan.
Here is a comparison with December 2016, Graves went off line last December for most of the 29th Dec.
This final plot shows the daily meteor activity throughout 2017, the major showers are marked, for more information on meteor showers go to http://meteorshowersonline.com/
Happy New Year
The beginning of the month saw some varying activity due to the Northern and southern Taurids. The Leonids around the 17/18 were preceded by higher activity on the 16th, also apparent on the comparison with 2016. Then a spike of activity on the 25th, several bright meteors were seen during the evening observing session, on the 25th, at the SPA meeting at Preston Montford in Shropshire .
I have included the meteor information to allow comparison with data. There were no indications of the fireballs reported earlier in the week along the south coast.
Next month sees the Geminids 13/14 Dec and the Ursids, 22 Dec, with the moon position and phase favourable to both, here’s hoping for clear skies.
Finally a screenshot showing the meteor detection on the zero frequency line having adjusted the offset on the funcube dongle.
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
A little after the event, but has taken time downloading / checking data after my eclipse chasing.
The daily rate shows a peak on the 12th August, however checking out the hourly rate shows the maximum hourly rate occurred on the 13th August at during 7 – 8 am with a max of 30 meteors. The maximum activity on each day was concentrated in the pre dawn hours.
I noticed the odd perseid in the USA but being a lot further south the radiant was a lot lower in the sky, quite close to horizon, which made life difficult when dark spots were usually surrounded by trees! With early starts each day it wasn’t feasible to wait into the early hours.
Below is data on rest of showers during August, September offers only minor showers.
