Hi all,

I just bought a SkyAlert Weather Monitor.  Have not been
down to the site to install it yet but I see at least one of you
has this device and are displaying its results out on the internet.

QUESTION:  in the following SkyAlert image, how do you tell if it
is likely to be cloudy?  Are you looking for the "Sky Temp" to
rise to someplace within the grayed areas?  How are the Gray
areas determined?

I had cloud conditions all calibrated on my Foster Weather Monitor but its communication
chip was damaged by a nearby lightning strike several months ago.  I replaced its comm chip
but was unsuccessful at restoring it to working order.  The device no longer seems to be
available from Foster...  Thus my purchase of the SkyAlert system...

Thanks!

Howard

Arp 38 (NGC 6412, UGC 10897 and others) is a nice spiral located approximately 74 million light-years away in Draco. In the ‘Spiral galaxies – companions on arms – low surface brightness companions’ class, it looks like Arp might have made a mistake. There doesn’t appear to be any companions. I have a feeling some of the knots in NGC 6412 were thought to be galaxies.

The galaxy and surrounding field is heavily obscured by IFN dust. The thickest clouds are cataloged in the Planck Galactic Cold Clump (PGCC) catalog - https://www.aanda.org/articles/aa/pdf/2016/10/aa25819-15.pdf.

Hi all

vdB 104 is a reflection nebula surrounding the 2.9 magnitude star sigma Scorpii. Sh2-9 is an emission nebula near the same star, so this is a combination of reflection/emission nebulosity:
