Well first the one I missed! At 0320 this morning I awoke to a crystal clear sky though the dawn was becoming apparent, so I decided to get up for a while and get the camera out. While I was photographing Venus and Mars (see other thread) a mag -2 Perseid streaked away from the Double Cluster area in the direction of Ursa Major.

I then took some widefields based around Pegasus as this seemed to be the right sort of distance from the radiant and was in the direction of the darkest sky.

One of my frames had not one but two Perseids in it, both traceable back to the radiant.

The bright star below left of centre is Hamal.



Looking forward to a great display!

Ha, I was still observing at 0320 BST! And the sky was definitely deteriorating with increasing high & mid level cloud as well as dawn twilight setting in.

Quite a few meteors last night, none spectacularly bright, some appeared to be Capricornids as well as a fair proportion of early Perseids - the Perseids certainly seem to be active this year!

Still very well done to get two in the same frame.

Great shot Paul!  It's always good when it's Perseid time again.  I saw 3 over about an hour or so last friday night when I was camping in the crystal clear, light pollution free skies of the Brecon Beacons.  I'm off in a week on my light pollution free holiday to wales specifically to observe the Perseids.  Now, all I need is some clear skies, hmmm....

Well caught paul - and hopefully a good omen for this year's peak - though of course the Moon could have been better placed!

Nice capture Paul!  Smiley

I observed meteors on July 28/29, 22:05-00:15 UT. ZNELM=5.8 (almost great sky conditions)
Activity was quite good  Smiley - total 26 meteors, though only 3 of them were Perseids

  • I was much surprised with activity of α-Cygnids (maximum on 15.07, ?)... Shocked
  • Perseids are currently faint, slow and not any intensive.
  • 01:11:25 - unusually long (>95°) and long duration (5.0...6.0s) meteor with faint trail. +4m (!). (PAU)
  • 02:00:46 - very beautiful one - very bright (-3m), whitish-blue, with two consequtive flares. Length ~40°, duration 1,4...1,5s. (SDA)
  • Does anybody knows something about β-Cassiopeids and γ-Draconids? I know almost nothing about their activity, but my software tells they're active (maximum on 29.07 and 27.07 respectively). Those 2 meteors might be sporadics if these showers aren't active.  Huh

P.S. I also look forward with A BIG HOPE to the maximum of Perseids this year. Roll Eyes

Great shot Paul! Hopefully we'll have some clear skies here in the States also.

That's a great catch Paul, very rare to get two Perseids in such close proximity in the one exposure..brilliant.  Smiley

There has been so much meteor activity lately, every time I look up I'm seeing Perseids and Capricornids, and with sucn strong activity at this stage it could only mean we are in for a good show during the peak. Looking forward to it!
