Eight Perseid session working GRAVES pre and post maxima has produced this result for me.

From the 2nd-3rd Aug until 12th-13th Aug, a steady increase in rates occured, (no surprise there!), with peak numbers around 03.00 to 04.00UT on the morning of the 13th after a sharp rise in counts from the 01.00-02.00UT numbers.

An initial "early Perseid" session I did on the 30-31st July seemed somewhat high in relation to some of the counts in early August. I then realised I'd managed to catch the tail of the max of the Southern Delta Aquarids, so totally failed to establish a baseline for the Perseids! Oops!!

Some of the more "interesting" pings around the max are also attached.

Regards, Les

I have results for all July and August to date.  I will look at your results and compare.  It does raise the point- what is the bet way to display hourly count rates?  Lines, bars (I favour), tables, colourgrammes (also useful to show diurnal changes and progression during month)  Also are your counts manual or automated in some way?

Are the blanks in your table where you were not monitoring or there was nothing to count?

Hi,

In response to Geminids questions, my counts are manual and blanks in the tables are simply where the setup was not switched on and monitoring.

I run my dongle into SDR# and have a screen grabber catch the screen every 45 seconds. I then manually look at each grab for a "ping" and then work out rates from this. A six hour "observing" session can therefore generate 480 grabs to individually view for meteors. Would be good to "automate" this to be able to run 24/7 but I'll admit that "speclab" and I do not see eye to eye.......... actually I think it hates me!!...... so I use the "low tech" approach listed. 

Regards, Les.
