NLC News



Mr Jens Jacobsen is trying to get in contact with NLC observers based in Denmark, with the intention of establishing a coordinated observing network in that part of Europe. Any observer who would be interested in contributing to this project should contact Jens directly:

NLC reported From Southern Hemisphere

NLC was observed from Davis Station, Antarctica (68 35'S 77 58'E) on 1998, February 18-19. Photograph and report of this event can now be viewed. Thanks to John French of the Australian Antarctic Division: Atmospheric and Space Physics for forwarding details of this unusual sighting.

News from NLC CAN AM

Mark Zalcik has completed his 1997 NLC summary from the North USA/Canada network.

Concerned at the recent depletion of observational data received from Weather Stations and Flight Service Stations operating in Northern America and Canada, Mark Zalcik (NLC CAN AM's coordinator) has prepared a discussion paper on the issue.

Man-Made NLC's

1997 February 22-23

Bill Burton and Jon C. Stewart-Taylor (Virginia, USA), following a Hale-Bopp observing session on February 22-23, observed unusual clouds in the deep morning twilight. Later, investigations revealed that these resulted from a rocket launched that morning at 0500 EST from the NASA facility on Wallops Island.

New Book On NLC Observing

Published by the International Association of Geomagnetism & Aeronomy, this book is now the standard reference manual for observing NLC. The book contains an updated and revised NLC classification structure and has a comprehensive selection of outstanding photographic images.

Midcourse Space Experiment

Following a lengthy series of delays and cancellations, the Midcourse Space Experiment (MSX) satellite spacecraft was successfully launched on 24th April 1996. MSX has a wide-ranging programme of data collection, for both the military and civilian sectors, including an investigation of Earthlimb Backgrounds. Principle targets of this project will be observations of aurora, airglow, mesospheric and noctilucent clouds, joule heated atmospheres and stratospheric warmings. The experiments are due to be performed on a daily basis, depending on the geographic, geomagnetic and seasonal variations encountered throughout the mission. Sensors will also be able to respond quickly to transient phenomena such as intense aurora and geomagnetic storm conditions.
