History

Historical Context

The July 28 1999 partial lunar eclipse, with umbral magnitude 0.3966, was catalogued by NASA’s Goddard Space Flight Center, reflecting systematic eclipse tracking. Occurring within the 21st-century series of 228 lunar eclipses, such events have driven agencies to expand public programs and real-time atmospheric monitoring, a trend echoed in today’s Chabot Space & Science Center streams.
