Astrolium's Cosmic Weather module is a daily sky dashboard: the aspect that defines the day, the Moon's phase, an hour-by-hour timeline in your own time zone, and the days ahead as a row of cards. It is included on the Free plan; see pricing for the rest.
It sits next to three free tools on this site. The sky weather calculator lists upcoming aspects for any moment, the void-of-course tool gives the full year of void Moon windows, and planetary hours covers the Chaldean hour rulers. For a public look at today's positions without an account, open today's sky.
What Cosmic Weather shows
The module describes the sky, not a chart. No client is attached to it, and the AI prompts behind it say so outright: a global sky briefing, never a natal reading.
The hero: one aspect, one number
Most daily feeds lead with a sentence. Cosmic Weather leads with a fact you can check.
The hero names the aspect, for example Mars square Saturn, then prints the orb to a tenth of a degree and the phase. A side gauge repeats the orb in large type. Where the Moon leads the day instead, the gauge switches to illumination, so the number on the right always matches the headline on the left.
Below the headline sits a line of plain facts: the phase of the aspect, the orb, and the Moon's illumination percentage. A short interpretation title and summary appear above it when one exists for that aspect, and the Ask AI button in the corner hands the whole calculated record to the assistant.
The timeline, in your clock
The timeline is where a practitioner plans around the day. Every event carries a time in the zone of your practitioner location, and that zone is printed beside the heading.
It collects these events:
- the estimated exact moment of the defining aspect, when it falls on that day
- sign ingresses
- stations, retrograde or direct
- New, First Quarter, Full and Last Quarter Moons, with the sign
- the start of a void-of-course Moon, with the time it ends
- the end of the void, with the sign the Moon enters
Each row has a small dot in one colour for a timestamped event and another for an estimated one, plus a badge that spells the precision out. Open Calculation details and the row names its source and precision in one sentence. Open What this means for a longer interpretation where the catalogue has one.
We label the difference because it matters in consultation. A void-of-course window read from source data and an ingress projected from planetary speed should not look the same on screen, and here they do not.
Days ahead as weather
The period grid turns each day into a card. The icon follows the defining aspect: a sun for a trine or sextile, a cloud for a square or opposition, a part-cloud sun for a conjunction, a moon when no major aspect leads. Under it you get the orb or the illumination, the phase badge, and the headline.
On the Today tab the grid shows the next seven days under the timeline. The 7 days tab puts the grid first. Month shows the whole calendar month in compact cards and selects today by default. Custom opens two date fields and accepts any range up to 366 days; if some samples fail to load, the missing days are shown as unavailable rather than filled from a neighbour.
Selecting a card moves the hero and the timeline to that date, and the timeline heading changes to name it.
Share the day, or publish for an audience
Share now builds a short factual text for the selected day: the date, the defining aspect with orb and phase, the estimated exact time if there is one, the Moon's sign and illumination, and a sources line stating that projected times are labelled estimated. Where the browser supports it, the device share sheet opens. Otherwise the text is copied to the clipboard. A Set up button beside it goes straight to the Telegram integration in Settings.
Astrologers who run a channel can go further on the Adept plan. Create audience forecast opens an agent that reads the calculated events for the selected period and proposes post options: a series for the week, a post for a lunation or a station, a lunar calendar, or a split across the twelve signs read by rising sign or Sun sign. It writes nothing until you confirm the plan, and an event the calculation does not hold never reaches a post. Finished setups save as templates in Report Studio and can run every day, every Monday or on the first of each month at 09:00.
Two limits are stated in the product rather than discovered later. A single day cannot be split by sign, because over one day only the Moon changes and twelve texts would come out almost identical. And prose posts cover about 92 days at most.
Where to go next
For a chart-specific view of the same planets, the transits module sets them against a natal chart with activation windows. For timing work on this site without signing in, use the sky weather calculator, the void-of-course schedule and the planetary hours calculator. Plans and the Adept features are on the pricing page.
