AAVSO ALERT NOTICE 137 (January 14,1991)
LAST LIST FOR MONITORING OF ROSAT TARGETS
Rho CasRho Cas (type semiregular) is a hypergiant star and one of the most luminous stars in our galaxy. Eruptions on these very rare, very massive stars produce huge mass ejections evidenced by dramatic spectral changes and optical dimming (an ejection in 2000 amounted to 10,000 Earths worth of material and caused a ~1.5-magnitude drop in visual brightness). |
Eta Carinae is one of the most interesting stars in the sky. According to predictions, 2003 could be a very exciting year for observing Eta Car. Below is a list of resources and information that can help you with your observations.

SUBJECTS:
1. 0505-68 YY DOR - POSSIBLE RECURRENT NOVA
2. 2247-14 IL AQR - EXOPLANET TRANSIT CAMPAIGN UNDERWAY
1. 0505-68 YY DOR - POSSIBLE RECURRENT NOVA
Event: Possible recurrent nova (currently classified in GCVS as NA, Nova 1937)
Discovered By: William Liller, Vina del Mar, Chile
Discovery Magnitude: 11.0 V
October 1, 2004: IL Aqr, known as GJ 876 in the exoplanet transit community, has two planets orbiting it. On October 21, 2004, the AAVSO will be conducting a ten-hour observing campaign to detect the largest of these planets, GJ 876b.
