The Handbook of the British Astronomical Association gives the Cusp Angle (CA), the angle of the event around the Moon measured from the nearest cusp. If you’re going to try to spot the precise moment Uranus starts to reappear, you’ll need to know roughly where on the Moon’s limb to look, especially if observing at high powers. The Cusps on a crescent and gibbous Moon. Happily, by this time the Moon has climbed to a much more amenable altitude of 21° or so. Without the same degree of distracting glare as at the beginning of the occultation, it’ll be easier to see Uranus. Uranus is hidden behind the Moon until about 11.21pm and 11.27pm BST (22:21 and 22:27 UT), from London and Edinburgh, respectively, when it starts to reappear at the dark limb (eastern limb) of the Moon. Depending on the ‘seeing’ conditions at the time, a high-power telescopic view could be spectacular. It will be fascinating to observe as this happen and as the occultation begins Uranus won’t instantaneously disappear from view, taking a number of seconds to completely disappear behind the Moon. Uranus lies about 50’ east of the Moon as they rise, but the Moon quickly close the gap.

Hubble Space Telescope’s take on the planet Uranus. By this time, the celestial pair has risen to about 12° to 13° above the eastern horizon. Uranus disappears at the bright limb of 77-per cent-illuminated waxing gibbous Moon at about 10.27pm and 10.37pm BST (21:27 and 21:37 UT) from London and Edinburgh, respectively. On Wednesday evening, Uranus and the Moon rise across the UK at around 8.55pm BST. Amazingly, Uranus has been occulted by our satellite each month from somewhere on Earth since February and that amazing trend will continue for the rest of 2022, including another event, on 5 December, that’s visible across the UK This exciting event can be seen from parts of Africa, Asia and Europe, including the whole of the UK. On the night of Wednesday, 14 September there’s a pretty rare circumstance to observe as the planet Uranus is occulted by the Moon. From London, Uranus disappears at the bright lunar limb at about 10.27pm and reappears at 11.21pm BST at the Moon’s dark limb. It’s clear that the original author of the binary designed the payload with both some trivial counter-forensics and anti-EDR detection methodologies in mind.” concludes the report.Uranus is occulted by a waxing gibbous Moon on the evening of 14 September. Using a legitimate image to build a Golang binary with Certutil is not very common in our experience or typical and something we are tracking closely. “Overall, TTPs observed with GO#WEBBFUSCATOR during the entire attack chain are quite interesting. The C2 domains employed in this campaign have been registered in late May 2022, the researchers shared Indicators of Compromise (IoCs) along with MITRE ATT&CK techniques. We have observed similar behavior with DNS exfiltration tools such as DNSCAT2.” continues the report. “This technique works by sending an encrypted string appended to the DNS query set as a subdomain. Once executed, the malware makes unique DNS connections, experts determined that the binary was leveraging a DNS data exfiltration technique by sending unique DNS queries to a target C2 DNS server. The binary encoded strings using ROT25 and is compiled using the Go programming language and obfuscated using Gobfuscation. The binary employs multiple obfuscation techniques to avoid detection and make analysis hard. The Base64 encoded payload, once decrypted, is a Windows 64-bit executable (1.7MB) called “msdllupdate.exe.” At the time of publication, this particular file is undetected by all antivirus vendors according to VirusTotal” “The image contains malicious Base64 code disguised as an included certificate.
