SpaceWeather.com have reported a strange pattern of summer NLC over the South Pole. See spaceweather.com/archive.php?view=1&day=01&month=03&year=2015 the overall frequency of NLC was very low and there was a dramatic dip compared to other years when the peak should have been.
This is very similar to my casual observations of the AIM south pole NLC images on SpaceWeather.com over the last few months. The number and extent of NLC seemed very low.
Unfortunatly you cannot use the archive facility on spaceweather.com to view the previous AIM South Pole NLC images - even though the date below the images is correct in the archived pages when you expand the image you will find it is 'todays' or the last image published.
You need to go to the AIM / LASP website at lasp.colorado.edu/aim/browse-images.php to see the daily summaries - not very impressive - mostly clustered close to the South Pole.
Hope we get better results this summer in the Northern Hemisphere though the Solar Activity seems to be decreasing which may have an impact.
