Introduction AstroCloud(Cui et al. 2015) is a cyber-infrastructure for astronomy research initiated by Chinese Virtual Observatory (China-VO) under funding support from NDRC (Na- tional Development and Reform commission) and CAS (Chinese Academy of Sci- ences). Tasks such as proposal management, data archiving, data quality control, data releaseandopenaccess,Cloudbaseddataprocessingandanalyzing,areintegratedinto the physical distributed platform. It acts as a full lifecycle management system and gatewayforastronomical dataandtelescopes. 1 2 ChenzhouCuietal. 2. Newfeature Since its lunch on May 15, 2014, many new features and remarkable improvements have been made to the platform. The current system consists of five channels, i.e. Observation, Data,Tools,CloudandPublic. Figure1. ChannelsofAstroCloud Proposalsubmissionsub-system(Xiaoetal.2015)wasre-designedtoprovideflex- ible management features for telescope managers. Configuration parameters for back- endinstrument, proposal submission, peer-review, andobservation timeallocation can bechangedbytelescope managerseasily. Figure2. ProposalManagementSystem Data query and access sub-system (Fan et al. 2015)was improved for better per- formance and interoperability. Tens of datasets hosted at the platform can be queried and cross identified through a uniform interface. LAMOST DR1(Luo et al. 2015), UpdateoftheChina-VOAstroCloud 3 the largest astronomical spectrum dataset with 2.2M spectra was open to the public in March2015throughthesystem. Figure3. DataQueryandAccessSystem A new dashboard is designed to give a user fast access points of frequently used resources andservices, andsummaryinformation ofthesystemandtheuser. Acquisition,ReductionandAnalysisofMulti-wavelengthAstronomicalData(MADARA) is a Cloud Computing(Li et al. 2015) based teaching and research environment for astronomical lectures and graduate students. Common used software packages, for example IRAF, DS9, CASA, HEASOFT, SSW, IDL, Python, to process and analyze multi-wavelength observation data are pre-installed. A virtual machine instance with thesepackagescanbeinitiated andreadyforusinginonlyfewminutes. China-VO Paper Data Repository, provides long-term storage and open access serviceforuserâA˘Z´spaperdata,whichincludesbutnotlimitedtables,figures,pictures, movies,sourcecodes, models,softwarepackages mentionedinhisscientificpapers.

Video streams provide live images taken from video cam- eras at different observatories. Gallery is a collection of beautiful pictures taken by AstroCloud users.

Inthemorning ofSep. 12,asupernova candidate 4 ChenzhouCuietal. wasdiscovered bya10-year old pupil. Inspired bythe news, number ofthe registered users of AstroCloud platform raised violently to 105K by the end of September. Two supernovacandidates discovered bypublicusersinOctober2015havebeenconfirmed byprofessional observations. In additional to the above user facing channels, several crucial functions are pro- videdbythebackend platform. Twoexamplesaregivenhere.
