Comet MAPS Hitting the Sun LIVE
Comet MAPS entered the solar corona and approached the sun, with its survival being an open question due to extreme conditions.
Watch on YouTube ↗Key takeaways
- 🎯Comets entering the solar corona face extreme conditions that make their survival highly uncertain, often leading to fragmentation or disintegration.00:50
- 💡Ultraviolet cameras are not ideal for observing comets, as they do not shine brightly in this spectrum, making them difficult to detect against the sun's glare.04:08
- 🚀Coronagraphs, designed to observe solar ejections like CMEs, can also detect comets passing close to the sun by blocking the sun's direct light.07:59
- ❓The visibility of a comet's interaction with the sun is limited by the capabilities of the observing instruments, particularly the preference for ultraviolet cameras which are less effective for cometary observation.30:08
- 📚Research the Kreutz family of comets to understand the most abundant source of comets in our solar system and their behavior.30:46
- 📈While some comets are abundant from sources like the Kreutz family, their passage near the sun is a high-risk event, with a statistically significant but not guaranteed chance of triggering solar events.30:46

The digest
This live commentary provides a detailed real-time observation of Comet MAPS as it enters and interacts with the Sun’s outer atmosphere, the solar corona. It captures the challenges of monitoring such an event, discusses the nature of comets approaching the Sun, and offers insights into the solar environment and space weather phenomena. The discussion also touches on related topics such as potential effects of comet-solar interactions, observational technology limitations, and space weather awareness.
Real-Time Tracking of Comet MAPS Entering the Solar Corona
The core event centers on Comet MAPS approaching and passing behind the Sun as viewed from Earth. Around [00:50], the comet is reported entering the solar corona, the Sun’s outer atmosphere consisting of highly ionized plasma. The observer uses the SOHO LASCO coronagraph imagery to monitor its progress, noting that the comet entered the LASCO C2 instrument's field of view at about 6:00 UTC ([07:52]) and is moving rapidly toward the Sun’s surface.
Zooming into observations, the comet is visually tracked as it crosses into the corona, and the observer explains the geographic relation from an Earth-based perspective ([02:36], [08:50]). The rapid transit means the comet will be past the corona in about an hour ([09:44]). Multiple satellite instruments, including STEREO and ultraviolet detectors, are employed to capture the event, but ultraviolet cameras reveal minimal brightness from the comet, complicating direct visual confirmation ([04:01]-[05:20]).
