A friend shared with me the following horary. He was traveling from Hong Kong to NYC for a 10-day vacation. Before boarding the plane in Hong Kong on Thursday 24 March 2016 , he decided to ask a horary question at 7:46 AM about how the trip would go. Here is the chart with Regiomontanus houses.
In this chart, the last degree of Aries rises (a late Ascendant). Mars, which rules the querent, lies in the 8th house conjunct its cusp. In traditional horary the 6th, 8th and 12th houses are considered unfortunate. In this chart there is a predominance of planets in houses 6, 8 and 12 — a caution that there may be problems with the trip, perhaps due to ill health.
Future trends are shown by applying aspects. Mars (the querent) applies to square Neptune. Squares generally indicate difficulties. Neptune here occupies his 11th house of hopes and wishes, suggesting that there may be difficulties achieving his hope for a good trip.
The trip itself is shown by the 9th house of long-distance travel. Jupiter rules the 9th and conjoins the 6th house cusp of illness. Jupiter is retrograde and lies in Gemini, the sign of its detriment, so Jupiter is not in good condition in this chart. Furthermore, Jupiter is barely separating from an exact square to Saturn in the unfortunate 8th from the cusp of the 6th of illness. Jupiter apples to square Venus and to oppose Neptune, both of which lie in his 11th of hopes and wishes. Jupiter also separates from a trine to Pluto which conjoins the MC, making Pluto (complications) an important factor in this chart.
Also noteworthy in this chart is that the Moon’s nodes highlight the axis of the 6th and 12th houses, again emphasizing illness and confinement.
The outcome: When he left Hong Kong, he was feeling run-down with some upper respiratory symptoms. Sunday night he woke with intense nausea and vomiting. On Monday he needed to go to a medical clinic because he felt so ill. On Tuesday the nausea had subsided but he woke with abdominal pain and returned to see the doctor. Instead of sightseeing, he spent a lot of time in bed in his hotel room. Because of his ongoing GI symptoms, he shortened his vacation and decided to return to Hong Kong three days earlier than he originally planned.
