Waxing Crescent · 20% Illuminated
Tuesday, April 21, 2026
Tonight's moon phase in Sofia is Waxing Crescent with 20% of the lunar disk illuminated. The Moon is currently described as "growing sliver." Moonrise is at 08:52 and moonset is at 01:35 local time. The next full moon is on Friday, May 1, 2026 (10 days away).

The current moon phase visible from Sofia is Waxing Crescent with 20% of the lunar surface illuminated by direct sunlight. A thin sliver of the Moon is now visible on the right side (in the Northern Hemisphere). The illuminated portion grows each night as the Moon moves further from the Sun in the sky.
From Sofia at latitude 42.7° and longitude 23.3°, the Moon rises at 08:52 and sets at 01:35 local time today. These times are specific to Sofia's geographic coordinates and will differ from other cities, even those in the same time zone. The Moon's position in the sky depends on the observer's exact location on Earth.
The lunar cycle from one new moon to the next takes approximately 29.53 days (a synodic month). During this period, the Moon progresses through eight named phases. The illumination percentage tells you how much of the Moon's visible face is currently lit by sunlight as seen from Sofia.
The Moon does not produce its own light. What we see as moonlight is sunlight reflected off the lunar surface. As the Moon orbits the Earth every 29.53 days, the angle between the Sun, Earth, and Moon changes continuously, altering how much of the illuminated half of the Moon is visible from our perspective on Earth.
The eight principal moon phases are:
The moon phase significantly affects both lunar photography and nighttime landscape photography in Sofia. Each phase offers different creative opportunities.
For detailed close-up photographs of the lunar surface, the best phases are the first quarter and last quarter. At these half-lit phases, sunlight strikes the Moon at an oblique angle, creating deep shadows along the terminator line (the boundary between the lit and dark halves). These shadows reveal craters, mountains, and valleys in sharp relief. A full moon, by contrast, is lit head-on and appears relatively flat with few visible surface features.
Recommended camera settings for lunar photography from Sofia:
For night sky and Milky Way photography near Sofia, the moon phase matters as much as light pollution. A bright moon washes out faint stars and the Milky Way core. Plan night sky sessions around the new moon when the sky is darkest. The five days centered on the new moon provide the best conditions for astrophotography.
Conversely, a bright moon (waxing gibbous to full) is excellent for illuminating foreground landscapes at night. The Moon acts as a natural fill light, allowing you to capture detailed foregrounds without light painting. Position the Moon behind you or to one side to light the landscape while keeping stars visible in the opposite direction.
Today's moonrise in Sofia occurs at 08:52 and moonset at 01:35. Unlike sunrise and sunset, which follow a predictable daily pattern that shifts by just one to two minutes per day, moonrise and moonset times shift by approximately 50 minutes later each day. This is because the Moon orbits the Earth in the same direction that the Earth rotates, so each day the Earth must rotate an extra 50 minutes for Sofia to "catch up" to where the Moon has moved.
This daily 50-minute shift means the Moon's visibility window changes dramatically over the course of a month. Around the full moon, the Moon rises near sunset and is visible all night. Around the new moon, the Moon rises and sets close to the Sun and is not visible. During the first quarter, the Moon is visible in the afternoon and evening. During the last quarter, it rises around midnight and is visible through the morning.
The exact moonrise and moonset times depend on Sofia's latitude (42.7°) and longitude (23.3°). Two cities in the same time zone but at different latitudes will see the Moon rise and set at different times. Cities closer to the poles experience greater variation in moonrise times throughout the month compared to equatorial locations.
On some days, the Moon may not rise or not set at all from Sofia's perspective. This happens when the daily 50-minute shift causes moonrise to skip past midnight into the next calendar day. When the table shows "--:--" for moonrise or moonset, it means that event does not occur on that calendar date.
Sofia experiences tidal patterns influenced by the Moon's gravitational pull. The Moon's gravity creates a tidal bulge on the side of the Earth facing the Moon and a second bulge on the opposite side. As the Earth rotates through these bulges, coastal areas experience two high tides and two low tides each day.
During full moons and new moons, the Sun and Moon align, combining their gravitational forces to produce higher-than-average "spring tides." During the first and last quarter phases, the Sun and Moon pull at right angles, partially canceling each other out and producing lower-than-average "neap tides." The current Waxing Crescent phase means Sofia is between spring and neap tide conditions.
