Noctilucent
Clouds
The northern season for NLCs began on May
26th. The first clouds were detected
inside the Arctic Circle by the NOAA 21
satellite. An instrument onboard NOAA 21 (OMPS LP) is
able to detect NLCs (also known as "polar
mesospheric clouds" or PMCs). For the rest
of the season, daily maps from NOAA 21
will be presented here:

Updated: Aug. 29, 2023
Each dot is a detected cloud. As the
season progresses, these dots will
multiply in number and shift in hue from
blue to red as the brightness of the
clouds intensifies.
What happened to NASA's AIM
spacecraft, which has been
monitoring NLCs since 2007? Earlier this
year, the spacecraft's battery failed.
As a result AIM is offline, perhaps
permanently. There may be some hope of a
recovery as AIM's orbit precesses into
full sunlight in 2024. Until then, we will
maintain AIM's iconic "daily daisy,"
frozen at Feb. 28, 2023, as a show of
thanks for years of service and hope for
future daisies:
