Dear All, Please remember that if anyone is out and about at the appropriate times and does NOT see NLC it is just as important to post the null observations. OR make sure you send them to Tom for inclusion on the observation page. This is to ensure that the seasonal results are not statistically skewed by only positive results. Also it shows the geographical spread of displays as NLC are not uniformly distributed entities. cheers, Bill.
My plan for the season is whenever it's clear and I have my camera I'm going to take shots of the evening sky (and where possible the morning sky too :S ). Trouble is it's actually seemingly never clear!
Whether I get any NLCs in shot is another matter, but either way it will get either a positive or a negative sighting
On the same night a person from N. Ireland reported a massive NLC display at 02.00 UT. They must have been mistaken?
Observer seen the NLC display east of Belfast, N. Ireland.
On May 31-32 I observed through to 02:30 UT from near Dalry, Ayrshire, Scotland. Any NLC visible in N. Ireland would have been seen from here too. I didn't see anything. Highlight of the night was an ISS pass! Will post my full list of May negative reports later.
Thanks very much Tom for the confirmation. I have been in contact with the person and despite telling him that no NLCs where seen by at least five different persons, he still believes what he saw. He must have made a mistake. There was certainly nothing from my location all night either.
With regards null observations would it be helpful if I also include a photo of it?
I wouldn't have thought this necessary, unless there's something unusual or you were uncertain about anything. The important details to include are location, date, time (preferably in UT) and description of sky conditions.
Negative observation from N. Ireland June 1/2nd. Period of obsv, 00.40 - 02.00 UT. No NLC seen. Clear sky however dark band of cloud covered northern horizon to a height varying between 5 and 7 degrees.
