  1. Was just checking outside and with no moon it seemed quite dark for a suburban area. 

    Looked up light pollution maps and found this. I thought the timeline on the light pollution map was running backwards.

    This is quite a basic map, but seems to show a reduction in LP over the last 30 yrs. Although locally I have found skyglow worse than it was 20yrs ago, because of new buildings and houses near the town centre. Quite a few estates on the outskirts of town turn most of the streetlights off at 23.30.

  2. Two great captures Leo 

    On the cloudy nights I was using 10 sec exp. ISO 2000 f3.2 with Tamron 17-50 f2.8 

    On the clear night 15 sec exp. same ISO f stop.

    As you know If a really bright fireball comes through, you would only need about ISO 400....

    Should be some clear skies during in the next few days

     

     

  3. 17 hours ago, Leo S said:

    By the way, a bit late but there might still be more to come in the next hour or three for anyone who has clear sky:

    "The International Meteor Organization notes that on August 14 between 1 UT and 2:45 UT (August 13th, 9–10:45 p.m. Eastern Daylight Time) Earth will encounter a trail of dust (called a filament) released by the comet in 68 BCE that could briefly boost meteor counts."

    Ok , what is BCE ?  

    Also I was thinking tonight is forecast clear for the southeast. Would it be worth having a short session of meteor spotting? Or are the Persieds out of range now? I think after the peak that number of meteors is tiny. I suppose it's always worth a look for some sporadics.

    Edit

    I see now 68 BCE is quite a while ago, it's fascinating how they know the exact date of this, although in the larger picture that is not long. 

  4. This says Persied numbers have decreased over the last few decades.

    23.30  14-8- 23

    Went outside to check the sky, there were some gaps and I could see the summer triangle. Saw two Persieds within three minutes, but the cloud is back for tonight.

  5. While out trying to pickup the Aurora (no luck this time), I saw a bright meteor in the north above the plough. It was heading from North east to South west. From about 70 degrees fading out at around 30 degrees. It was white and fading to orange and left a brief trail. Time was 01.22 , I think it was a Persied. 

    The moon and Jupiter looked nice together , and the Pleiades nearby.
