Bright #NoctilucentClouds extending up to at least 40 degrees above the horizon at around 03:10BST over Bishopbridge. #nlc #nlcnow @NLCalerts @chunder10 @cogie_s @simon_weather @sjb_astro @mars_stu @saloplarus @SnowbieWx @MetJam_ @LividLFC @196photo @LincsSkies @StormHour

Finally a Large Bright Beautiful display of #NLC #NoctilucentClouds #lichtendenachtwolken ..my first this season! Seen this morning , June 30th 2023 from #Heerhugowaard the Netherlands. @helgavanleur @BuienRadarNL @StormchaserNL @NLCalerts #NLCnow @mrmiddendorp @SonyNederland

Faint and subtle #NLC (noctilucent clouds) from #Rousay #Orkney last night (20230614 23:45UT) @nlcnet @NLCalerts @sjb_astro

Muie, Sutherland 14/15th June 00.30-01.00 faint Noctilucent clouds within the twilight arc Midges where fun 🙄 @NLCalerts @theauroraguy @James_Akrill @chunder10

Getting brighter at Muie Sutherland 😚 @chunder10 @NLCalerts

Finally this years first @NLCalerts I had to stay at home so I just took this out of my bedroom-window ;) #Denmark @NightLights_AM @astronomicca @dartanner @mikesaltsman194 @treetanner @AngelBrise1 @chunder10 @cogie_s

@NightOwl_247 @James_Akrill @Liam_Ball92 @cogie_s @sjb_astro @KerrieDoodles @andy_stones @MetJam_ @mars_stu @StormchaserUKEU 1) Earth’s rotation from west to east and 2) general evolution of most NLCs seem to be from east to west.

@James_Akrill @Liam_Ball92 @NLCalerts @cogie_s @sjb_astro @KerrieDoodles @andy_stones @MetJam_ @mars_stu @StormchaserUKEU Sorry, am new to this, why will it be a morning show if they are centred over Eastern Europe now? If the clouds are in the mesosphere will we able to see them in the UK when the sun is at -11° below the horizon tonight? Saw 1st NLC’s last August and can’t wait to see them again

#NoctilucentClouds on the IAP cams over on the continent. Worth a look when it gets dark if your lucky enough to have clear skies. Cloudy here in Lincs. 🤷‍♂️ @NLCalerts @cogie_s @sjb_astro @KerrieDoodles @Liam_Ball92 @andy_stones @MetJam_ @mars_stu @StormchaserUKEU #NLCnow

@NLCalerts Denmark, just now.

NLC in Latvia now

Good show of NLC in Latvia 👌👌

@phi48 Yes!

MAARSY radar readings showing signals of Polar Mesospheric Summer Echoes (PMSE), indicating 1) cold enough temperatures for NLCs & 2) presence of strong mesospheric electron density gradients. Although correlated in ways, PMSEs don’t necessarily mean NLCs though, but a good sign

@chunder10 Indeed 😁😁

@NLCalerts Aye...always gotta take them with a pinch of salt

@Rainmaker1973 @ilaks @NightLights_AM Why are you not releasing the DM screenshots forgiving the rights to, this would give more clarity to everyone and would exonerate you?

Correct me if I am wrong, but I tend to think this partial halo CME comes from an eruption in AR 13220, which is close to central meridian, that is, in the Earth strike zone. It may arrive on Feb 18 if it arrives.

THE SUN TODAY: 1) SSN down to 85. 2) X-ray background stable with a few low-level C flares. 3) A small region behind the NE limb. 4) Three new regions emerging in the east. 5) Five CMEs yesterday.

1-second exposure from last night. The aurora was BRIGHT!
